Protecting wetlands and the life in them requires recognizing the biodiversity of these ecosystems. Waterfowl and shorebirds that are ecologically dependent on wetlands are used as environmental indicators. This research was conducted in the winter of 2021 in order to investigate the species diversity of wetland birds in Poldakhter city. Half-winter census data for a period of 13 years (2009-2020) was received from the General Environment Department of Lorestan province. Simpson's photo index and Simpson's dominance were used to investigate the species diversity of Poldakhter wetland birds. During the statistical period under review In Poldokhtar wetlands, 10 orders out of 19 orders, 16 families out of 84 is and 60 species out of 545 species identified in Iran were counted and recorded, which were 52.6 percent of the order, 19.04 percent of the family and about 11 percent, respectively. Iranian bird species have lived in Poldokhtar wetlands. 68.3 percent of Poldokhtar wetland bird species are in the category of unprotected and normal species, 26.67 Percent in the category of protected and protected species and 5 Percent that include species. Vanlellus gregarious, the world's highest conservation species (CR), and Aythya ferina, a vulnerable species (VU), Phoenicopterus minor, and Phoenicopterus minor Oak duck (Aythya nyroca) live in correct the endangered species (NT) category. In Poldokhtar wetlands, 53.3percent of birds were wintering birds, 30 percent were migratory birds, 8.3 percent were summering and hatching birds, 6.7 percent were normal (four seasons) and only 1.7 percent were summering birds without hatching. The results of the investigation of species diversity indicators of Poldakhter wetland birds showed that the year 2013 had the lowest species uniformity and the year 2018 had the highest amount of species diversity. Therefore, Poldakhtar wetlands are one of the important wetland habitats in the region and play an important role in the migration of waterfowl and wintering waterfowl.

Tanodar wetland with an area of 1000 hectares is one of the largest wetlands in Lorestan province, which is located 10 km northwest of Dorud city. In this study to investigate the biodiversity of wintering birds in Tanodar wetland in 2017-2020 from species diversity indices (Shannon-Wiener and Simpson photo), species uniformity ( Smith-Wilson and Simpson dominance indices were used. During the study period 41 species of birds were recorded in Tanodar wetland, which belong to 10 orders, 13 families of birds in Iran. The results of biodiversity indices of birds in Tanodar wetland showed that in 2020 the highest species diversity, and 2017 had the highest uniformity of bird species. The trend of biodiversity indicators in Tanodar wetland is sinusoidal. The species of social gypsy rooster (Vanellus gregarius), which is in the highest conservation category (CR), was observed and recorded in this wetland in 2019 with 400 individuals as winter crossing migrants. In terms of bird survival in Tanodar wetland, 53.65 Percent were wintering birds, 29.26 Percent were migratory birds, and 17.09 Percent were normal (four seasons).

Protecting wetlands and the life in them requires recognizing the biodiversity of these ecosystems. waterfowl and shorebirds that are ecologically dependent on wetlands are used as environmental in dicators. Bishe Dalan wetland with an area of ​​913.5 hectares is one of the largest wetlands in Lorestan province, which is located in the south of Boroujerd city and on the edge of Silakhor plain. In this study, species diversity indices (Shannon-Wiener and Simpson photos), species uniformity (Smith-Wilson indices and Simpson dominance) were used to study the species diversity of Bisheh Dalan (2017-2020). In Bisheh Dalan wetland, 9 Orders out of 22 Orders, 13 Families out of 78 Families and 48 Species out of 545 Species Identified in Iran, Census and registration, which are 40.09 percent of the order, 16.66 percent of the family and about 8 percent of Iranian bird species have lived in Bishe Dalan wetland. the results of bird species diversity study in Bishe Dalan wetland showed that 67.90 percent of the bird abundance of three species of green duck (Anas platyrhynchos), Common fox (Fulica atra) and Gypsy rooster (Vanellus vanellus) and about 41.66 percent of birds in the situation is protected and endangered. In terms of species diversity and species uniformity, 2019 had the highest rate of indicators. in general, the trend of heterogeneity and uniformity indices in the forest wetland is a sinusoidal corridor.

Determining the trophy status is one of the assessment and analysis methods of the ecological balance of wetland ecosystems, because the sustainability and continuity of productivity based on these unique ecosystems requires proper monitoring management and control their environmental conditions because increasing nutrients affect all levels of aquatic ecosystems, including changes in species abundance, migration, reduction of biodiversity, and changes in the structure and composition of communities. Therefore, a suitable method should be used to determine the trophy status, or in other words, the production capacity of an ecosystem. Conventional methods for determining the amount of trophy are based on three physical, chemical and biological parameters. Lorestan province due to its unique construction has unique wetlands, including 11 Poldokhtar wetlands with an area of 142.7 hectares, Bishe Dalan wetland with 913.5 hectares and Tanodar wetland with an area of 1000 hectares. In this study, to evaluate the trophy status, sampling of phosphorus (TP), total nitrogen (TN) concentration or Carlson trophy index (TSI) was used in Poldokhtar, Bishe Dalan and Tanodar for summer and winter of 2019. Based on the annual average of Carlson index, Poldakhtar and Bishe Delan wetlands are in mild mesotrophic trophy conditions and Tanodar wetland is in the eutrophic category. In the wetlands of Lorestan province, the sediment load of suspended solids and water turbidity have been exceeded these wetlands limits and has had destructive effects on the unstable wetlands` body due to the annual entry of large amounts of sediment from the catchment, development of gardens, various recreational withdrawals in Boroujerd and Doroud, increasing the level of river water pollution caused by municipal and industrial wastewater, also, wastes from city and rural recreation centers and wastes from point sources of pollution such as warm water fish breeding ponds.

New methods of risk assessment can significantly reduce the severity of risks and consequently the environmental damage and move towards sustainable development. In this study, using the DPSIR model, the threats and environmental values ​​of Poldokhtar wetlands in the ecological, hydrological and social areas were evaluated and based on the threat score, values ​​and relationship between threats and values, the assessment of wetlands vulnerability and strategies Management was provided in response to the driving forces, pressures, situation and effects of risks. The results showed that ecologically, hydrologically and socially, droughts, fires, and wetland drainage resulted in reduced biodiversity, increased water turbidity and reduced water retention and functional reduction of hunting and hunting area of ​​Poldokhtar wetlands. Effortless. The highest impact of ecological threats on wetland birds was 16.1 on average and the least impact on threats on arid plants with average 2 Environmental risks with a mean score of 10.3 would have an impact on water retention during the period of wetland dehydration, and a functional reduction of 8.6 percent wetland hunting and fishing area was the most important social risk impact.

Determination of trophic status is one of the methods for assessing ecological balance of wetland ecosystems, because sustainability and productivity based on these unique ecosystems require proper monitoring and control of their environmental conditions. Therefore, biological and ecological studies are necessary before any activity is established. Tanudar Wetland with an area of 1000 hectares is one of the largest wetlands of Lorestan Province, 10 km northwest of Dorood. In this study, physical and chemical characteristics of Tondar wetland sampling were used to evaluate the nutritional status of Carlson (TSI) based on total phosphate (TP), total nitrogen (TN) and phosphorus to nitrogen (PN) Sampling of Tanudar wetland was used in summer of 2019. The results showed that based on the Carlson Trophic Index (TSI), trophic wetland Tanudar level is in eutrophic conditions. wetland Tanudar to its location, natural conditions and hydrological conditions, the is mainly drained from the highlands of Silakhor plain and tira River Dorood, Therefore, any upstream loading such as orchard development, diversified recreational harvests in the river, increased levels of dark river water pollution caused by municipal, industrial wastewater, and point source pollution sources such as warm-water fish ponds have crossed the Tanudar wetland. And it wound deeper on the current unstable body. Therefore, in the current conditions, the quantitative and qualitative provision of the wetland ecological right of the wetland is one of the most obvious requirements and management issues of the wetland.

Today, Conservation of natural resources regardless of the role of indigenous communities for modern protection and sustainable productivity, itchr('39')s not possible; because the participation of local people in the conservation of the natural capital an effective and big step is to Protect them. Gorem Belmak Wetland is the largest wetland in Pol-e Dokhtar township with an area of 562 hectares in 1996 by the primary beneficiaries, with the construction of a drainage ditch, seven-kilometer-long canals were drained into the Kashkan River. The present study, which was conducted in the fall of 2019, in terms of practical purpose and is a descriptive-correlational research that the data collection technique is a questionnaire before training and after training. The population Statistics examined in this study 37 students mixed the first class of high school is Shahid Momeni. Students trained in 7 days, which included 5 training sessions that combined a combination of questions and answers, group discussion, lecture, and data analysis, used the Chi-square test. The results of evaluating the wetland attitude of the agents of "public knowledge of the wetland" and "participatory management of wetland restoration" of students before teaching indicate the score of 12.08 with a standard deviation of 1.81 and after teaching with an increase of 4.58 the average score to 16.66 with a standard deviation of 1.57. Among the 5 variables of these two factors, the variable of participation in environmental culture of wetlands with 4.96 had the highest increase in scores after training. Comparing the average score of students chr('39')attitudes based on the Chi-square test shows a significant difference with a 99 percent probability of confidence between studentschr('39') attitudes before and after education.

Environmental Impact Assessment is an important management tool that identifies natural and anthropogenic environmental hazards and their wide-ranging impacts and determines appropriate control calculations. Correct and accurate knowledge one of the threatening factors of wetlands Based on their importance and impact can provide the basis for preventing and counteracting these factors more precisely, as well as preparing and implementing wetland conservation and environmental management plans. The vulnerability assessment method of Poldokhtar wetlands in this study is based on EFMEA failure states analysis method. for this purpose, first identify the most important environmental risks and threats in the hunting and hunting area of Poldokhtar wetlands in three categories of ecological, hydrological and social threats to 17 threats, then based on three variables: "probability, severity and extent of impact" Numerical values of each threat were determined and ranked according to the range of changes in five categories. The results showed that ecologically: wildfires and drainage in Gori Balmak and Piqué wetlands, hydrologically threatening to increase suspended sediment load, periodic droughts, and drilling deep and semi-deep wells in wetlands and social aquifers: low levels Environmental attitudes and knowledge of wetlands by the local community, lack of expert and wetland environments in the Department of Environment of the city and province are the most important threats in the 11 wetlands ecosystem of Poldokhtar. Overall, 88.2 percent of the risks were classified as risk-free, low- and medium-risk, and only 18.8 percent were high and infinite, requiring immediate action by wetland conservation and mitigation authorities.

Water floods and floods in residential areas have always been one of the most common natural disasters in Iran after the earthquake that endanger human life. Between 2000 and 2008, approximately 99 million people are affected by floods worldwide each year. Kashkan River Basin with 8 sub-basins with an area of 9275.66 square kilometers, constitutes 22.4 percent of total Karkheh basin, with 290km length and 26 percent slope of the steepest and most flooded Karkheh basin. The results of statistical analysis on the instantaneous discharge data of Kashkan basin showed that from 1963 to 2019, 58 floods with average discharge moment of 1062.78 cubic meters occurred. In terms of time distribution, 65 percent of the floods in March, April and May and in terms of discharge rate 36 percent of the floods are more than 1000 cubic meters. The highest frequency of floods was observed in 1990-90 with 19 percent of floods and 14 percent of floods were severe, 22 percent moderate and 64 percent small flood. According to the Gamble distribution, a 200-year flood with a probability of 0.995 percent flood occurring at an instantaneous discharge of 4489.77 cubic meters with a tolerance of 535.06 cubic meters in the Kashkan Basin. As a result of the floods on 1 April, 14 people were killed and the damage was estimated to be 103.014 billion USD. The main causes of floods with an instantaneous discharge of 6,000 cubic meters per second in the Kashkan Basin can be attributed to precipitation with an average rainfall of 112.3 mm on 1 April and 321.5 mm for 9 days from 24 Mars to 1 April, respectively. Kashkan Basin, The occurrence of a flood with an instantaneous discharge of 3350 cubic meters on 5 March 2019, the absence of a significant reservoir dam for flood control, Impact of Babazid Bridge as a dam and runoff behind the bridge up to a radius of 5 kilometers and reaching the bridge ramp to the breaking point, thereby increasing the amount and velocity of the flood discharge to Poldokhtar, Decrease in river bed between 1 and 13 m in coastal wall reconstruction after flood on 4 February 2005 as a result of reduced capacity of Kashkan River in Poldokhtar during floods.

Determining the conditions for water quality and the status of the trophy is one of the methods for assessing and assessing the ecological balance of wetland ecosystems, because the sustainability and continuity of productivity based on these unique ecosystems requires proper management of the monitoring and control of their environmental conditions. Therefore, conducting biological and ecological studies is necessary before any deployment of activity. Dolan Bayshah wetland is one of the largest wetlands of Lorestan province with a total area of 913.5 square meters and is located south of Boroujerd city and on the margin of Silakhor plain. In this study, the water quality index (WQI) was calculated based on 5 parameters: nitrite (NO2), nitrate (NO3), turbidity (TURB), dissolved oxygen (DO), acidity (PH) and Characteristics of Carlsson Trophy Status (TSI) based on total phosphorus (TP), total nitrogen (TN) and phosphorus to nitrogen (PN) ratio were used to analyze the physical and chemical characteristics of four sampling stations of Dalian bischled water in the summer of 2017 The results of this study showed that according to the Water Quality Index (WQI), this wetland for aquatic animals at poor quality sampling stations cement channel in the lower part of the village of Kaper Jodaki and Drainage area  ganjine is in good condition at station Perpendicular cement channel village of Kaper Jodaki and is located in the very poorly in Water Quality Station Bayshah Dolan wetland river  gle rod. Based on the Carlsson Trophy Index (TSI), the tropic level of the sandy lagoon is characterized by a slight mesotrophic trophic condition and the entry of mesotrophic conditions.

Considering the Situation and Conditions of Wetland Ecosystems in the World, Many Different Species of Birds are Ecologically Dependent on the Lagoons and Through Various Compromises these Unique Ecosystems are used as a Suitable and Important Habitat To Make. Therefore, The Study of the Variation and Fluctuations in the Population of Aquatic Birds During Different Years can be a Biological Indicator of the health Status or the Presence of Threats in Wetland Ecosystems. In this Study, to Study the Biodiversity of Birds  Waterfowl and Waders the Wintering of Poldokhtar Wetlands in 2009-2015, from Species diversity Indices (Shannon-Wiener and Simpson's Image), Species Richness (Margaluf index), Species Uniformity ( Smith-Wilson and Simpson Dominance Indexes) and for the Similarity of the Species of Birds in Different Years, the Morrista index was studied using Ecological Methodology, Species Diversity and Richness total of 16986 bird species from 6 orders, 14 dwarfs and 43 species have lived in the wetland wetlands. The density of birds at the surface of the wetlands is 52.9 and 58 Percent of the Habitats have Waders habitats and 42 Percent have Waterfowl Habitats. The Results of Survey of Biodiversity Index of Birds in Poldokhtar wetlands Showed that the Highest Variety, According to the Biodiversity Index of 2009, the lowest and the highest in 2012, the Highest Species Diversity, 2013 and 2009, the Lowest Level of Species Uniformity in the Year 2013 and the Lowest in the year 2009 Have Been the Least Species Richness of Birds. Based on the Morrista Similarity Index, the Most Similar species of the birds community in Poldokhtar wetlands related to 2012 with 2014 is the Similarity of 1 and the Least Similar Species in 2015 with 2011 with Similarity of 0.79.

Wetlands are some of the most beautiful landscapes that can be creator or stimulus of a development process for sustainable development in local communities and ecosystems if they are properly planned and managed for tourism development. Geo-tourism or geological tourism has been used as the equivalent for environmental tourism in recent years. Environmental tourism is a natural resource-based tourism market. Considering the fact that the hunting and fishing area of 11 Poldokhtar wetlands has a high potential in the field of tourism, creating the necessary infrastructure and introducing it as a geo-tourism attraction pole in the province with regard to the high power of these wetlands, Tourism and help to grow and expand the economy, increase income and raise the level of employment in the region is necessary. In order to determine the Geo-tourism sites, it is necessary to identify and evaluate susceptible sites. Therefore, in this research, two Rhineard qualitative models and Pereira quantitative model were used to evaluate the tourist potential of Poldokhtar wetlands. Based on the results of the Pereira model, the geomorphologic characteristics of the wetlands (4.49), visibility (2.65), protection value (2.15) and applied value (4.05) were about 86.6, 58.8, 71.6, and 57.8 Percent of the standard pattern surface. Based on the Rhineard quality model, under the indicators of scientific value, the level of sustainability with the score of 506 and the long-standing geography with 1 point, with a good and excellent quality level and below the value added indicators, are below the ecological index (good), Cultural (good), beauty (good) and economical (weak). The results of this study indicate that the hunting and fishing area of Poldokhtar wetlands requires strengthening the conservation status, changing the attitude of the current islands management and turning to the management of the ecosystem, creating infrastructure for tourism facilities.

Among the aquatic ecosystems, wetlands are ecologically and environmental important because they are as: the place of accumulation and acceptance of nutrients and non-Nutrients, the protection of biodiversity of animals and plants, natural purification of water quality, the Effects of Micro-Climi in the region, play an effective role. So, evaluation the quality chemical, physical and water is essential for quality control, pollution control and biodiversity conservation. qualitative in dicators and hydrological bulletin are the methods that can be used as a strong management tool for decision making on qualitative and quantitative water resources management. Poldokhtar County has 11 wetlands with 8 permanent and 3 seasonal wetlands, known as the wetland city of iran. in this research, which was held in the summer of 2017, water qualitative water quality index (WQI) was used to determine the quality of drinking water and aquatic ecosystems based on the calculation of nine physical and chemical parameters of water including Nitrite(NO2), Nitrate(NO3), Alkalinity, Hardness(Mgca), Turbidity(TURB), Electrical Conductivity(EC), Dissolved Oxygen(DO), Acidity(PH) and biological oxygen demand(BO), The Statistics of Physical and Chemical Characteristics of Water in Wetlands in Summer of 2017 In order to estimate annual water volume in wetlands, rainfall data, surface runoffs and groundwater nutrition as inputs of water and only water outlet of evaporation wetland, 2005 as normal precipitation, 1993 and 2008, were very severe droughts, and physiographic characteristics of the catchment area and Water balance equation were used. the results of this study based on the WQI index and the hydrological bulletin showed that their water quality of drinking water is in the good and poor classes, and in terms of ecologically clean water, the changes volume and area of the annual water area of the wetlands in the year extreme drought and fatigue, 1747545 cubic meter, 29.89 Hectares is showing.

Before each use of a Resource, it cable source of knowledge and ability necessary to be a source of policy and planning to besestionable. The comfort of knowing byvkly meaty in different geographical areas. Can be a vary important role in land development and ultimo aptly to help deprived areas. their analysis Using climatic data of daily mean air temperature, drying temperature, average wind speed in meters per second dominant and air temperature Puldokhtar synoptic stations centigrade during the period 1390 - 1377 and then Environmental climate in three models Evanz, Baker and Trmvhygrmtryk index is used to the situation of human comfort is achieved Environmental indicators Climate results indicate comfort conditions in the Persian month October months, April, November and March are And thermal comfort in summer conditions is not, And comfort during cold conditions and cool temperatures are mild. Analytical Methods In this research,

One of the strategies that has been introduced to strengthen deprived areas is expanding tourism in areas having necessary potentials to develop tourism. Climbing as one of the natural ecotourism branches is manifested in a spatial model of tourism in nature that has been neglected in different ecotourism sources. Oshtorankuh is one of the unique attractions of the country in west. In this study using latitude and empirical formulas, the angle of altitude, the hour angle, azimuth sun at different times of season's days were calculated and then slop morphological factors, slope (the amount of radiation received in different seasons), and altitude were combined to consider the feasibility of ecotourism activity of climbing in the region by logic and social overlapping functions in order to determine suitable climbing zones in different seasons. The results indicated that without considering the direction of radiation with appropriate zone for this activity in different seasons of the year based on sunlight suitable climbing zone showed minimum (23.02) and maximum (80.88) differences Based on daily changes, the suitable tourism zones had the highest and lowest daily fluctuations in midwinter (10.31) and midsummer (5.64). Therefore the best time for climbing in this region was in midsummer.

Surface runoff form rainfall to that part is called the gradient along the surface of the earth now and into the flow of surface or subsurface of the basin is out. Hydrological models that can be structural according to operating features of the basin affect the desired interaction phenomenon and it's with a reasonable approximation to show. River Basin of Kashkan under basin Karkheh basin is important. For modeling "Rainfall, runoff," statistical data from 14 storms during the period 1389-1360, the following is a watershed moment Poldukhtar that the water has been used. Then, based on five characteristics as the independent variable and seven Haytvgraph 14 storm hydrograph characteristics as dependent variables, a multivariate regression to assess Account different models for Rainfall runoff modeling has been. And the results showed that among a variety of methods, a multivariate regression, linear methods, explained, and power have the most decisive for modeling Rainfall - runoff are. Then, based on multiple regression to provide a regression model Rainfall - runoff discussed.. the multivariate regression modeling has been at tempted models for evaluating models Rainfall - Runoff using A number of criteria and indicators in clouding, correlation coefficient, standard error, the relative error of estimation and verification, the mean absolute percentage error, Relative mean squared, error squares Square of the mean square error, the average absolute error is used. R^2 Obtained show that 0.796 percent of maximum intensity of storm runoff in the basin Kashkan related to three factors (MIS), the amount of excess Rainfall (ASP) and duration of excess Rainfall (DSP) is.

The city as the focus of human activity has no choice but to accept the structure and affected functions of natural systems in order to ensure its sustainability. Green space used as a necessary and unavoidable part of cities plays an important role and its deficiency can greatly harm the life in cities. In the present study, the distribution and analysis of locating the intra-city parks of Pol-e-Dokhtar through the neighboring functions in GIS environment investigated. As far as spatial distribution is concerned, only 9.32 percent of the total area of the city is used as parks. The results of analysis of lands used as parks shows that approximately 67 percent of the subareas of parks are indicated as ‘totally appropriate’ and ‘appropriate’ and nearly 33 percent are considered as “completely inappropriate” and “inappropriate”. Considering the complete compatibility, the best locating relates to Fadak Park, while the worst one is related to Azadegan Park. From among the three scales of the parks in the city, the radius performance of the parks has been appropriate in local scale. The park capita in Pol-e-Dokhtar is presently 2.66 square meters. Regarding the 8 square meters for each person, the city is faced with a shortage park area of 156458 square meters.

With all the importance of water in the economy Iran is، every year floods volumes high of waters and Prolific soils of the country and access out to the desert، lakes and seas Delivers. the hydrological model can be structured according to the basin and operating characteristics affecting desired interaction phenomena and its behavior show with reasonable approximation.
