The problems and challenges of the transportation business include environmental pollution, reduced amount and increased cost of energy resources, material and moral harms of increased accidents, surveillance, and management of suburban transportation, increased wasted time, and the quick expansion of transportation needs, particularly during rush hour in the metropolises worldwide today. Progress in public knowledge, better living standards, the increased value of time, and the introduction of novel sciences and technologies regarding this business have led to higher expectations. This phenomenon has become a serious threat from one point of view and a chance for profitable investment from the outlook of marketers and experts. In this respect, the ITS (intelligent transportation system) has been employed to tackle these problems. Hence, this study addressed reducing gasoline consumption using the ITS on Iran's Karaj-Chalous axis. The statistical population of the research includes vehicles moving during the eight busy days of September 2017 from 1 am to 24 pm on the Karaj-Chalous axis. Selective sampling was not performed. The results proved that the ITS decreased the travel time on the Karaj-Chalous axis and, therefore, the gasoline usage.

This study aimed to estimate the environmental effects of reducing CO2 emissions by using ITS in Iran (Case study of Karaj-Chalous axis). The present research is applied in terms of purpose-based classification. The idea of applied research is to develop applied knowledge in a particular field. Furthermore, this research is descriptive-correlational in terms of method and nature. The statistical population of this study is the vehicles traveling during the eight busy days of September from 1 am to 00:00 in the Karaj-Chalous axis in 1398 during the study time. No other specific sampling was performed. All calculations and analyzes were performed using Excel and 10Eviews software. The results revealed that the application of the intelligent transportation system had decreased travel time on the Karaj-Chalous axis and, therefore, reduced the carbon dioxide (CO2) emissions. The outcomes indicated that the use of the intelligent transportation system (ITS) during the eight days of the research had decreased 10129069 kg of carbon dioxide emissions in the Karaj-Chalous axis.

In recent years, reducing energy consumption and greenhouse gas emissions in the building sector has attracted a lot of attention. As in other parts of the world, the construction sector in Iran also has a large share of energy consumption. As a result, low consumption and even zero energy buildings, as an alternative solution in solving this problem, have attracted the attention of scientists, researchers and policy makers. One of the main challenges in designing a zero energy building is to find the best combination of passive solutions to reduce consumption and optimize energy performance in the building in such a way that the energy performance of the building and the thermal comfort of the residents are not negatively affected. This article presents a method for multi-objective and multi-variable optimization based on building simulation, which is carried out in three main stages: building energy consumption simulation, two-objective optimization process and multi-criteria decision making for zero energy building design using renewable energy sources. Reproducible. The studied design parameters are: direction of the building, angle and depth and length of the protrusion of the shades, insulation thickness of external walls, temperature adjustment points for cooling and heating, ratio of window to wall area, heat transfer coefficient of windows and thickness of roof insulation. In addition, the considered renewable energy sources are: photovoltaic panels and wind turbines. In order to achieve a net zero energy building, considering maintaining the thermal comfort of the residents, a multi-objective genetic algorithm with non-dominated sorting has been used. Finally, in order to determine the most optimal answer in the Pareto diagram, the elimination and selection method compatible with reality has been used. The results show that climatic conditions and the appropriate selection of architectural parameters are very important and vital in reducing building energy consumption. Based on the results, the use of energy optimization solutions in Tehran leads to a 25.3% reduction in energy consumption. In addition, there is a significant potential for the use of photovoltaic systems in Tehran to provide energy for homes.

In recent years, the phenomenon of dust has become one of the most important environmental challenges around the world, which is one of its negative effects on the agricultural sector. Dust on agriculture can affect the growth and performance of plants by affecting the photosynthesis process and also by increasing the leaf temperature, and by providing favorable conditions for the occurrence of diseases and disrupting the population balance of pests against beneficial and predatory insects and Also, the effect of reducing the efficiency of spraying plants against pests and diseases creates the grounds for causing damage and reducing production in various agricultural and horticultural products. The purpose of this research is to estimate the willingness to pay to reduce the effects of dust on the agricultural sector of the centers of dust production and its surrounding areas in Alborz province.

In order to achieve the goal of this research, first, according to the map of dust centers prepared in Alborz province, the affected villages were determined. Ahmedabad areas are affected by dust. Then, using the Contingent valuation method (CVM), the willingness of people to pay to prevent and reduce the negative effects of the dust phenomenon on the agricultural sector was calculated using 400 questionnaires. It should be noted that the number of questionnaires was determined by using the Cochrane relationship and the population of the villages affected by dust.

According to the results of this research, the correct percentage of the estimated willingness of farmers to pay in order to reduce dust damage is 73% in the derived model. Also, the amount of expected value (WTP) was calculated equal to 165423 rials (approximately equal to 5.5 dollars). According to the population of the affected area, the total value of preserving agricultural products against the phenomenon of dust is equal to 2743375032 rials ($9144.58) per year. The results showed that the variables of age, number of working people, education, income and environmental awareness index have a positive and significant effect on the willingness of farmers to pay to preserve agricultural products against dust. In other words, the increase in age, the number of working people in the family, the increase in the level of education, the increase in income and the increase in awareness of farmers increase their willingness to pay.

The evaluation of the willingness to pay of farmers in Alborz province in order to reduce the dust damage on the agricultural sector showed that increasing awareness, education and experience (age) increases the willingness of farmers to pay dust control costs. Therefore, it can be said that in order to control and stabilize the sources of dust production in Alborz province, the knowledge and awareness of farmers regarding the negative effects of dust on the agricultural sector should be increased by using advertising training classes and so on. As a result, the willingness to pay farmers will increase. Then, in the form of non-governmental organizations or cooperative projects with the government, he designed and implemented programs to control and stabilize dust production sources with the participation of farmers.

Sperm cryopreservation has become an indispensable tool in reproductive biology. However, maintaining fertility in frozen sperm is very important. The aim of this study is to investigate the effects of selenium nano-particles on the storage of dog semen at 4 ˚C during a period of 48 hours. In this study, 20 ejaculates were collected from 4 mix dogs and diluted in a Tris-based diluent. Then, they were divided into 4 parts in control and treated with 0.5, 1 and 1.5 µg selenium nano-particles groups. Sperm parameters including evaluation of total and progressive motility sperm, motility characteristics and viability of sperm were evaluated for 48 hours. The obtained results showed that in concentrations of 1 µg [progressive sperm (27.03±1.48), total motility (49.48±1.27) and viability (41.40±1.03)] and 0.5 µg [progressive sperm (30.76±1.67), total motility (53.18±1.54) and viability (43.15±1.58)] of selenium nanoparticles compared to the control group, but in the concentration of 1.5 µg was lower than the control group (p< 0.05). As a result, the present study showed that adding selenium nanoparticles in concentrations of 0.1 and 0.5 µg to dog semen can improve the parameters of dog semen after liquid storage, but in concentrations of 1.5 µg it causes toxic effects and overall agitation. And it reduces sperm viability.

Today, human society has faced various environmental crises, such that environmental challenges such as air, water, and soil pollution have put people's health at risk, and as a result, dealing with environmental crimes has become increasingly important because it harms social security.
The basic question of the article is that the criminal policies in Iran's legal system have the necessary efficiency to protect and protect the environment, especially in order to prevent encroachment and occupation of protected areas? This article deals with this issue with descriptive-analytical method and library sources, and the findings show that criminal protection in its current form has not been able to provide the goals of the legislator properly and appropriately. In this article, with the aim of explaining the criminal tools in order to protect the right to a healthy environment, while addressing the guarantee of criminal executions and the existing challenges, new approaches are made in this field.

Severe land use change in recent decades has affected the ability of ecosystems to provide services, so it is necessary to be aware of the trend of these changes and their impact on ecosystem services for sustainable land management. The aim of this study is to evaluate the impact of land use change on biodiversity services in the Shafarood watershed in Gilan province.

The present study consists of three steps: 1) Extraction of past and present land use maps using Landsat satellite images using ENVI 5.3 and ArcGIS 10.3 software 2) Prediction and extraction of future land use maps using Scenario Generator tool of InVEST software and finally 3) Quantitative evaluation and modeling and mapping of ecosystem services related to biodiversity using the Habitat Quality model of InVEST software.

The results showed that habitat quality has decreased sharply over time under the influence of land use changes, and habitat degradation has increased sharply so that the average habitat quality for the entire study area for 2000, 2020, and 2040 are equal to 0.88, 0.64, and 0.41respectively. Also, the average habitat destruction for the whole Shafarood watershed in 2000 is equal to 0.0021, in 2020 equal to 0.0042, and for 2040 equal to 0.0061.

According to the obtained results, it can be argued that the increase of human development activities with the aim of acquiring and exploiting natural lands has caused irreparable damage to the structure of natural lands and plant and animal habitats and the continuation of such a process will lead to the risk of complete destruction of these unique resources.

The governments of developing countries noticed that environmental taxes, in addition to helping to achieve environmental goals, also make it possible to achieve other economic and social goals such as reducing the unemployment rate. In the past, policies aimed at minimizing the unemployment rate have a negative impact on other policy goals because they reduce private incomes, especially for people on government benefits. Therefore, it is politically difficult to implement environmental policies. However, for green tax reforms to be socially acceptable, complementary policies such as public spending cuts should be minimized to reduce the burden of green taxes on the private sector.

Green taxes lead to a decrease in social welfare and have a greater impact on endogenous public expenditures. Therefore, minimizing public expenditures as a complementary policy to promote the labor market effects of green tax reforms in developing countries will fail. Was.

As a result, policymakers in these countries should look for other ways to help them reduce the green tax burden on business, which in turn will enable them to implement environmental tax reforms.

In the present study, Spss26 software is used to describe the statistical population and research data, Excel software is used for the Dimtel technique and fuzzy Delphi analysis and fuzzy ANP software. In the second level, the fuzzy Delphi method is used using Excel. In the third level, Fuzzy Network Analysis Process (FANP) was used based on the constituent questions and variables. At the last level, Dimetal technique was used to check the relationships.

The current research is an applied research in terms of classification based on the purpose. The purpose of applied research is to develop applied knowledge in a specific field.

Also, the current research is a descriptive-correlation research in terms of method and nature. The statistical population of this research is the cars that traveled during eight busy days of September, from 1 am to 24 pm, in Karaj Chalus axis in 2018 during the study period, and no other specific sampling was done. All calculations and analyzes were done using Excel and 10Eviews software.

The results showed that the use of the intelligent transportation system leads to a reduction in travel time on the Karaj-Chalos corridor and consequently reduced gas emissions. carbon dioxide (CO2).

The findings showed that the use of the Intelligent Transportation System (ITS) in the 8 days of the study has led to a reduction of 2521 tons of carbon dioxide emissions in the Karaj-Chalos axis.

One of the challenges faced by governments in the last century is environmental crises such as temperature increase, climate changes, environmental pollution, loss of plant and animal species, etc. European and North American or Japanese governments often use green finance laws and instruments to advance their environmental protection policies.

 In this research, in the first step, the researcher will identify the effective criteria and models on the green tax by using the expert analysis approach using the fuzzy Delphi method, and after screening, he will introduce the implementation models. In the second step, by using the causal theory of the Dimtel method in the fuzzy evaluation environment (due to the high precision of the fuzzy method approach, this approach has been used in the analysis), the tolerance evaluation of the executive models will be carried out. Finally, the correlation executive model will be presented. The fuzzy network analysis model, which is a comprehensive approach to the green tax open environment problem, will classify and grade the identified patterns.

Using analytical and library methods, this study shows that tax, as one of the financial policy tools, plays an important role in sustainable growth and development and ensuring social justice. The main goal of this research is to investigate the classification process of green tax in environmental instruments, in order to achieve sustainable development.

Iran can increase the share of its tax revenues and leave a positive impact on the quality of the environment by designing and implementing green tax (environmental taxes) as one of the common tax bases in the countries of the region.

Green taxes are one of the old economic tools in environmental protection that have been used for many years in different countries. The use of this tool is very necessary in the cases suggested by environmental economics and prevents the release of excessively optimal social pollutants. The use of green taxation as a favorable mechanism to help curb climate change and promote environmentally sustainable occupational practices was supported.

The study of green tax design is the main subject of this research. Research and study of the practical application of green tax It is necessary to learn the background information about it. Definition and classification of green tax is the existential reason behind green tax. Statistically, it was determined using Cochran's test and by designing a questionnaire and checking their validity and reliability (in the case of the reliability of the questionnaire, the compatibility coefficient of the comparisons was 0.0196, which is less than 0.1, so the comparisons can be made. () In order to evaluate the results with the help of Excel and SPSS software, green tax variables were classified. Green was identified and after screening the executive patterns were introduced. In the next step, with the help of Demetel method in the fuzzy evaluation environment, the executive patterns were evaluated in relation to each other. Classified Took.

The various dimensions studied in this study are the core efficiency, the dimension of maintaining and improving the quality of the environment, the dimension of applicability in various fields, the dimension of increasing income and effective in the economy, and the dimension of sustainable development, respectively. Among the dimensions, it could be used with a weight of 0.97, with the highest weight. In the second place, the axial efficiency weighs 0.1873. The average dimension is equal to 0.1659.

Basically, this tax is used to reduce the negative impact on the environment caused by business activities. Given the importance of green taxes, it is suggested that green taxes should be included in the government's environmental policy portfolio. Environmental taxes require companies to offset their pollution costs with environmental activities or pay higher taxes.

The sludge produced in the oil refinery is very harmful due to the significant volume and complexity of the compounds, and its reasonable disposal is very important for environmental protection and sustainable development. During the effluent treatment process in the oil refinery, contaminated industrial sludge containing toxic substances is produced, which contains poly-aromatic hydrocarbon compounds and is classified in the group of hazardous wastes.

In this study, the life cycle evaluation of disposal methods in two scenarios of landfill and incineration on industrial sludge of oil refinery in Iran has been investigated. Regarding, using life cycle assessment software, openLCA with CML-Baseline Impact Assessment Model, different environmental impact categories are examined and using weighting and dimensionless method of each effect class in the two defined scenarios, the best scenario has been identified in terms of the environment.

The results from 11 categories including acidification, climate change, reduction of Abiotic, in two parts of fossil fuels and factors affecting final reserves, toxicity in three parts (drinking water, seawater, and soil toxicity), Eutrophication, Human toxicity, ozone Layer depletion, and photochemical oxidation have been evaluated. The results show that the least environmental effects on human health indicators and plant species are related to the landfill scenario. The sludge incineration scenario, which is sent directly to the incinerator, has been selected as a worse scenario with the highest emissions of carbon dioxide, methane and nitrogen oxides into the environment.

The results of dimensionlessness in the two studied scenarios showed that Scenario 1 (Landfill) with a value of 2.94 × 10 -6 and Scenario 2 (waste incineration) with a number of 5.42 × 10 -6 the least destructive effect on the environment, respectively.

Iran is ranked as the ninth largest greenhouse gas producer in the world, with an annual emission of nearly 180 million tons of CO2 by thermal power plants.. The purpose of this research is to simulate and optimize the optimal economic and environmental load dispatch and a portfolio of efficiency improvement strategies on both supply and demand sides in MT1, MT2, and EEP scenarios in using the Long-range Energy Alternative Planning (LEAP) modeler and its OSeMOSYS optimizer system. We do this using the time series data from 2008 to 2018 of the country's energy balance. Our modelling allowed us to estimate the current situation and forecast of supply and demand of thermal electricity, types of costs, and the amount of greenhouse gas emissions  for the whole country over a 20-year period (2011-2030). We identified the most efficient policy for improving the environmental economic efficiency of the thermal power sector in line with the Paris Agreement in the form of the best scenario through cost-benefit analysis by determining the optimal dispatching of thermal power plants. The results showed that all alternative scenarios with a reduction of more than 15% emissions and environmental economic benefits of more than $ 8 billion compared to the BAU scenario would achieve Iran's INDC goals and meet our commitments under either a conditional or an unconditional agreement.

This paper aimed to create a composite index for environmental quality. Since the results of empirical studies on economic - environmental variables nexus, considering different environmental indicators, are not consistent with each other; it seems necessary to use a comprehensive index that includes all dimensions of environmental pollution.

Using 6 environmental indicators related to two groups of selected OPEC and OECD countries for the period 2010 to 2019 and using three methods including principal component analysis, kernel-based principal component analysis, fuzzy robust principal component analysis, the creation of a composite environmental quality index is examined.

The results showed that FRPCA method has more efficiency and ability in weighting environmental indicators than other methods due to having the lowest error criteria. Therefore, using this method, the composite index was calculated. Moreover, the results showed that along with the upward trend of economic growth, the quality of the environment follows a downward trend in OPEC countries and an upward trend in OECD countries.

 Based on the results, policy recommendations as well as new perspectives and suggestions for future studies are presented.

Reviewing the Function of many environmental conservation organizations over the past decades, including in Iran, shows that the focus of environmental orientations and policies, due to the lack of accurate and reliable information, is more dependent on the application of instructions and guidance methods, and less Quantitative management approaches are used. Therefore, this study is aimed at modeling the process of land use changes in the last thirty years (1987-2018) and predicting the future status in case of continuation of the current trend and using improper management patterns. For this purpose, the InVEST software is used to analyze the present situation and to draw future conditions. The results in map form provide a good opportunity for managers and decision-makers to infer trends in future changes and modify management patterns to improve conditions. 

In this study, satellite images of Landsat 5, 7 and 8 According to years 1987, 2000 and 2018, were used for land use mapping in Jajrood protected area through extraction in ENVI 5.3 remote sensing software and ArcGIS 10.3 software. The accuracy of the classifications has been evaluated. According to the purpose of the study the area of study is divided into 10 user units. These units include poor rangelands, rich rangelands, planted forests, agricultural lands, barren lands, dam, residential areas, rivers, dirt and paved roads and the status and area of each user unit was determined.Finally, the scenario generator model of the InVEST software version 3.6.0., which uses a completely new approach to quantify and map, was applied in mapping the status of the future.  

According to the results of the past 30 years, the extent of residential areas, roads and planted forests has increased, and the extent of river distribution has decreased, as a result poor rangelands increased and rich rangelands decreased as well as changes in barren lands was clearly visible. So that, the extent of the barren lands has declined by the year 2000 due to the conversion  to man-made use  (near residential areas) and poor rangelands (due to favorable weather conditions, including suitable rainfall). The situation in the Barren areas during the period ending in 2018 has increased due to the bad weather (drought) and the irregular grazing of livestock and the conversion of poor rangelands into the Barren areas. The agricultural lands have increased over a period of time due to its proximity to residential areas and then a downward trend has taken place due to increasing land value. In recent years, the Mamlou Dam has also been constructed and operated in the area. In fact, because of Jajrood's proximity to large city of Tehran and the increasing population, the need for ecosystem services in the area has increased, and man-made uses being replaced natural land uses.Future forecasts showed that the extent of planted forests, barren and residential areas would increase; rangelands and agricultural lands would decrease. During the study period, rich rangelands marked as the most reduced area and residential areas marked as the most increased area.

The Jajrood Protected Area has undergone significant land use changes over the past 30 years due to human intervention. These changes have been caused by economic and social changes. It has been accompanied by management challenges in adherence to safeguards and efforts to achieve the defined goals for such areas. The changes of natural land use and the replacement of man-made use in the face of unnecessary development have undermined the natural landscape of the Jajrood Protected Area. This study showed that changes in multiple ecosystem services will act as major drivers of human change through changes in land cover / land use.In addition to identifying land use change, identifying suitable areas for natural capital conservation, man-made use development and sustainable land use, spatial development planning can be carried out in a way that reduces future uncertainties. It will result in making informed decisions and foster synergies in both environmental and development sectors.

Extensive changes in land use over the past few decades have posed a major challenge to the ability of ecosystems to provide services. Therefore, a better understanding of the impact of these changes on the ecosystem services is essential. For this purpose, in the present study, while extracting the land use map for the past and present, the land use map for the future was predicted and extracted using the Scenario Generator tool of InVEST software. Then, the effects of land use change on ecosystem services related to habitat quality in Normab Dam Basin of Golestan province were evaluated using the Habitat Quality tool of InVEST software. The results showed that due to severe changes in land use and conversion of natural lands, especially forest lands into agricultural and residential lands, the quality of habitats has decreased from 2000 to 2018 and land degradation has increased by the same amount. The forecast for 2036 also confirmed that if the current trend continues, the decline in habitat quality will be more severe and land degradation will increase. Based on the results, the average habitat quality for the years 2000, 2018, and 2036 is 0.8, 0.71, and 0.59, respectively, which indicates a sharp decline in habitat quality. Also, the average land degradation for the years 2000, 2018, and 2036 is 0.016, 0.020, and 0.025, respectively, which indicates an increase in degradation over time.

Groundwater resources are the most important source of fresh water in the world. In Iran which is located in the arid and semi-arid region, mismatch of consumption needs with rainfall time along with climate change has increased the demand for groundwater. Excessive extraction of groundwater in the Alashtar Watershed reduced the water level in the aquifer of the plain and water resources of this area have faced a negative balance. Due to the inherent limitations of the country's water resources and increasing the split between supply and demand, the use of economic instruments and the establishment of the water market for optimal allocation of groundwater is a necessity. Accordingly, this study in order to determine the market price of groundwater with the aim of accurately identifying the local markets for groundwater and also measure the views of local water market operators about some of the strategies for advance the water market designed and implemented. The statistical population in this research was all rural exploiters are the main reservoirs of groundwater in the basin who contribute to the buy and sale of these resources. Regarding market prices in the study area, the average price of groundwater was 1,749 Rials per cubic meter, and the total value of groundwater was estimated as 555,307.5 Milion Rials. The results showed that in 103 villages there is a market for the buy and sale of groundwater. Those villages that have a local groundwater market, 76% of the villages have been established by creating popular organizations and the water regulatory council and 43% of the villages by create a bulletin board agreed to facilitate the buy and sale of groundwater resources.

This study aims to identify the importance of biodiversity in the development of ecotourism in Khar Turan National Park or Touran Wildlife Refuge in Iran.

This is an analytical survey. First, the map of the most vital habitats in the study area was prepared through locating the land points in GPS using GIS, The study used Landsat 7 (ETM+) data (updated in 2010). For this purpose, Arc GIS software, Version9.2 was used. A modified questionnaire was used to record users’ opinions and the importance of natural attractions in terms of biodiversity. The sampling method is a cluster random technique with 764 samples. Exploratory factor analysis is used to analyze the data.

The southern and eastern parts of the study area are desert (with 57%). Rangelands and plains, mainly in middle parts, cover 40% of the region. Moreover, there are 3 mountains (3%) in the northern part. There are 16 protected species in the list of biodiversity of this region. From the touristschr('39') point of view, the most important attractions related to wildlife are hunting, sport, recreation, education, and research and economic benefits, respectively, gun hunting has the biggest weight (with 0.75) followed by equestrian-related attractions (with 0.63), and animal-watching attractions (with 0.59), while economic benefits and drawing attractions carried very little weight, with 0.14 and 0.18, respectively

The study area has great potential for ecotourism. However, due to the high tendency of tourists to commit environmental violations and the low awareness of them and the local community about the consequences of environmental crimes, it is needed to apply management principles including education, planning, and making environmental laws.

Groundwater resources management is one of the most important issues of natural resources management. Lack of proper management of these resources has caused serious problems such as land subsidence, aquifer salinity and the annihilation of wetlands. With population growth, has increased demand groundwater and led to water scarcity in many parts of the world including Iran. Estimating the economic value of groundwater is a fundamental step in water resources management strategies. The present study was conducted using interviews and questionnaires to estimate the average willingness to pay the population of the villagers living in Alashtar Plain. In this regard, some of the most important socio-economic variables of the studied population and their role in optimizing the management of groundwater resources have been studied. The statistical society in this research includes the population of villagers residing in the Alashtar Plain as the beneficiaries of groundwater resources in the area with a sample size of 490 was calculated by the Cochran formula. However, the average willingness to pay to protect groundwater resources for each household of the Alashtar Plain was estimated as 1,758,920 Rials per year. Results showed that the total value of groundwater protection in the Alashtar Plain is 8,913 Milion Rials per year. The protective value of one cubic meter of groundwater for the population that has stated their willingness to pay is based on a contingent valuation method of 208.647 Rials. It was also observed that the offered price variables, annual household income and level of education significantly affect willingness to pay for the respondents. Given the fact that there is no market for groundwater non-use value, the findings of this paper can be a powerful tool for decision making and water resources management for water sector managers.

Today, ecotourism is referred to as a tool that seeks to realize the pleasures and benefits of tourism, but strives not to diminish the natural and ecological value of the area. The purpose of this study is to determine the effective criteria for ecotourism site evaluation and ecological board capacity to plan for ecotourism in Shahrood protected areas.

In the first step, site evaluation criteria were compiled and rated by experts. Fitting was done by LISREL software. The data layers were then weighted and overlapped by pairwise comparison. Subsequently, zoning was carried out to determine the area and capacity of the physical real and effective range for ecotourism.

The final model of ecotourism evaluation consists of 8 dimensions and 20 criteria. The model fit was good and acceptable (GFI 0.942). It is also suitable for ecotourism at 66474 hectares. The study area consists of 3 areas of mountain forest, mountain and plain and desert. The effective range for the mountainous forest area is 1743 and for the mountainous and plain area is 1765 and for the desert zone is 3123.

In Shahrood city protected areas, environmental board capacity is not observed and is more than threshold tolerance. As a result, ecotourism needs to be at the forefront of tourism planning in the area of ​​conservation principles.

Due to problems of Urmia Lake, currently, several strategies have been proposed to restore it by the professionals. But it should be noted that the implementation of each plans and project within the watersheds requires the participation of stakeholders and farmers in the watersheds. Due to the lack of attention to stakeholders, many natural resources management and development projects has been failed. Therefore public acceptance and participation of stakeholders in some of the approaches taken to restore Urmia Lake are investigated in the present study. The used tool was the questionnaire in the present study filled by field survey to the study area and interview with stakeholders and the obtained results were analyzed. The results showed that the irrigation system change from traditional to pressure irrigation system with 91.45% approval rating, if implemented, can be considered as the most successful strategy among the investigated strategies. The payment of compensation to farmers for non-utilization of owned farming lands had the appropriate acceptance with 53.55%. Also the 50.25% of stakeholders will be readymade for the use of species with low water demands instead of the use of species with high water demands if the government support. The increase of stakeholder's water charge cant be a great success to reduce cultivation and thus reduce agricultural water use. Finally, so through these plans, irrigation system change plan be in the executive priority, and the next priority the payment of compensation to farmers and farming pattern change are implemented.

Wetland is a main natural ecosystem that has been exposed to a high amount of destruction over time. One of the reasons for the destruction of these resources is inefficient economic systems for proper valuation that has resulted in reinforcing the idea that these services are free of charge and also indiscriminate use of these resources and lead to irreparable damages. Accordingly, probably the first step in protection of these resources is offering reliable estimates of their real value to improve beneficiaries’ and stakeholders’ knowledge. This study attempted to determine willingness to pay of citizens in Ardebil province to protect the Shorabil lake using contingent valuation method (CVM) based on designing and filling the required questionnaires. In this regard, 218 questionnaires were filled in the summer of 2016 in Ardabil province and then were analyzed. The results showed that 53.21% of the respondents would pay an average 32,135 IRR per family member per year to protect the Shorabil lake. According to the results, the total protection value of Ardebil’s Shorabil Lake was estimated as 21.398 milliard IRR per year and its protection value per hectare was estimated as 125.872 million IRR per year. To achieve integrated view of the effective management for authorities, it is recommended that other aspects of Shorabil lake values including recreational, cultural etc. would be considered in similar research.

Planning to increase production and tends to increase the efficiency of human resources in productive organizations without estimating the economic costs imposed on the organization, cause the actual value of safety is ignored in workplaces. Among the financial cost of the productive organizations, the subject of safety promotion through decreasing the probable hazards will cause to impose the amount of extra costs to employers that are often faced them with the reluctance and therefore they will try to decrease these mentioned costs. The object of this study is to determine the numerical value of safety from the perspective of the refinery staff through computing the amount of money which the staff tend to receive to tolerate unsafe conditions in the workplace. This amount will be equivalent to the importance of preventing accidents and promoting the safety condition in the workplace from the perspective of the labor force.
In this study, by applying Contingent Valuation Method (CVM) and determining the amount of willingness to accept (WTA) of employees in exchange for the waiver of improving safety in the workplace, the economic value of safety in Esfahan Oil Refining Company was estimated from the employee's perspective.
For this purpose, a questionnaire was provided and by creating a hypothetical market scenario for safety as a non-traded goods, data relating to the safety value were asked from the number of 140 operational employees and analyzed by applying 2-steps questionnaire including the pre-test and final test during 2014.
Based on the results of this study, the mean of willingness to accept (WTA) a month for each employee at the refinery was estimated at 2 million and five hundred thousand rials. The total economic value estimated for the safety of the refinery personnel for 1,300 people employed in operational units, estimated 39 billion rails.
Considering the total annual cost of refinery safety that is 6,700,000,000 rials, it was clear from the employee's perspective, the economic value of safety is 5.8 times greater than the cost of refinery existing safety programs conditions in the workplace.
According to this point of view, the need to review the annual budget required to implement safety measures described and from an economic point focusing on the search for optimal conditions for market efficiency and cost effectiveness of the safety measures is important.

Using convenient interpolation method can result to generate more precise and more accurate maps. The aim of this study is to determine the most appropriate interpolation method from a variety of Kiriging, invers distance weighting and variety of Co-Kiriging to zoning and drawing hydro-statics curves of Razjerd complex. For this purpose, the pressure of 60 different points of Razjerd complex was examined. The performance of inverse distance weighting (IDW) in pressure zoning was weaker than the Kiriging; and by increasing the power of reverse method, amount of R2 was decreased and the amount of RMSE was increased. The gained maps of simple Kiriging method had shown a perfect match with statistics obtained from installed logger barometers in complex. Generally, because of the grate accuracy, less computing and less requirement to data, the simple Kiriging method recommended to zoning pressure.
