Measuring the quality of the urban living environment is the first step in managing it. The purpose of this research is to evaluate the quality of the urban environment in four neighborhoods of District 17 of Tehran Municipality as examples of inefficient fabrics in the south of Tehran. 55 indexes are used. The data of 29 indexes were obtained from statistical documents and sources, and the rest were obtained through surveys. According to Cochran's model, a sample of 378 household heads out of f 28235 households heads who are residing in the studied neighborhoods were selected randomly to answer the questions of the questionnaire. The documentary data, are adapted to the survey data in the range from 1 to 5 considering the Iranian standard ranges. The state of the quality of environment for each index is stated as a percentage of favorable conditions. Findings indicate the unfavorable state of the quality of the environment in the studied area. 11 environmental indicators show a relatively better state so they have almost 50% of favorable conditions. The physical structure in all the studied neighborhoods is lacking in terms of allocating land to public and service uses. Moghadam neighborhood shows the lowest and Boloorsazi neighborhood shows the highest environmental quality in all the dimensions. To improve the quality of the environment, it is recommended to accelerate the renovation of the urban fabric by faciliating the regulations and using the space that will be obtained from undermining the railway that passes across the neighborhoods.

Site analysis in the architectural design process involves obtaining numerous factors. Obtaining these factors requires a comprehensive assessment system and an accurate understanding of it. In this study, environmental impact assessment (EIA) is applied for a parametric assessment and simulation of vision in the site plan analysis process of the Shams-e-Tabrizi complex in Khoy city. This quantitative research was conducted based on modeling and simulating techniques. Valid architectural application software such as Rhino and Grasshopper were used to assess the impacts of parameters accurately. For the vision analysis and assessment, factors such as site context, neighboring buildings, green areas inside and outside of the site, outlying buildings and landscapes, topography, and landmark buildings. The results indicated that topography and neighboring buildings had the highest impact on the calculations of desirable vision in this site among the studied factors. Besides, inside-out and outside-in vision were analyzed and assessed separately and point-to-point through coding in the application. The calculations of the EIA algorithm revealed that the cells that received a score of five and higher were great and optimal ranges for design and construction. Analytical components of the site, such as vision, could be used directly and effectively in the design process parametrically and through algorithm building. Unlike the traditional methods, this method leads to incorporating the analysis stage into the design. The modeling proposed in this study has two advantages. First, it allows evaluating the existing designs and preparing a generator for new designs. In addition, it provides a component of generating site analysis for the final design and a tool for measuring final designs (whether implemented or not).

the purpose of this study is investigating the environmental impacts of coastal sustainable tourism in Anzali port city. Nowadays, tourism activity is one of the major sources of income for Bandar Anzali population, which certainly will continue to grow in the future decades. In this research, according to the subject and its theoretical issues, the survey method, used which is one of the most important quasi-empirical methods and has a great application in social and human research, and then statistical tools and techniques applied for classifying, Sampling, coding and analyzing and finally Delphi model was used for providing effective strategy and proper planning. because this research assessed and recognize development of tourism in Bandar Anzali, and provided effective strategies for improving it, based on its specific goals, is functional, and the rate of tourism growth damages to the anzali environment, has been high at 37.3%. Finally, measuring changes of city from tourists perspective who traveled to this city for several times showed that 44.4% of tourists believed that changes in the city are better than before. In terms of tourism facilities, in this city's regions, 54.4 percent of the experts believes that this city facilities is in average level.

The human relationship with the earth, over time, is always changing. This, in turn, has had a decisive impact on the use of urban lands. Therefore, in order to control urban growth, it is very important that, by identifying the ecological potential of the environment, the process of future development of the city be directed and managed in order to minimize the negative environmental impacts of natural resources of the city. With this view, after the implementation of the evaluation indicators through the system model, it has been tried to provide appropriate solutions for predicting future development of the city with an emphasis on environmental aspects. Therefore, while assessing the ecological capability of urban development in Sari using a system model, the zones in the form of very suitable and relatively suitable land parcels of urban development along with inappropriate land were identified. A very suitable class for urban development system model covered an area of about 433.143 square kilometers, equivalent to 11.22 percent, and a relatively suitable land had a surface of 126.29 square kilometers, equivalent to 34.3 percent of the city of Sari. Finally, it was concluded that 3,103 km2, which is 84.84% of the total 3662.151 sq. km of the area of Sari, cannot be developed for the creation of urban elements and other uses due to the indicators defined in the systemic model (Makhdoom). Undoubtedly, in order to preserve the ecosystems and environment, following this task seems necessary for the authorities to develop urban areas in future.

Compost is one of the urban waste management strategies that aim to reduce the volume and weight of materials to be repelled, reduce the spread of flue and fat, recycle resources, and reduce the cost of disposal. In order to comply with environmental laws and regulations in the framework of adaptation of an environmental development plan, an Environment Impact Assessment (EIA) plan for compost plants required. Accordingly, Leopold‘s checklist and modified matrix methods have been used in the environmental assessment of the Zahedan composting plant. according to the information obtained, it was determined that the area is not inhabited and in other respects, due to the researches and land use maps, no specific ecological and socioeconomic complications are identified within 10 km of the plan, and the land of the plot is mostly muddy and rough. The only factor that can specifically increase the radius of the effect of the plan is the direction and amount of 120-day winds of the province, which is usually from Zabol to Zahedan, which, due to the appropriate distance to the site, does not affect the city‘s residents. In total, the option of doing a design with +0.94 versus non-performing option with -3.7 has a full advantage and the plan is strongly recommended for improvement plans and corrective actions. Based on the review of the long-term effects of the project in the exploitation phase on leachate and its leakage, the health hazards of the factory for the employees and the external environment (mainly from insidious insects and animals), smell pollution and contamination of the product.

The purpose of this study is to investigate the status of landfill in the city of Cain and facilitate management operations to improve or change the location of these areas in the city of Cain ... In this study, we tried to investigate the existing conditions in the waste management of the city of Cain. Suitable and effective in the development of waste recycling and energy recovery industries. For this purpose, after carrying out library studies and collecting required maps, surveys and compilation of the characteristics of each landfill were carried out and field assessment was carried out and then the location of the areas was determined by GPS, and finally, the environmental limits Ambient landfills of the city of Qa'en with the system. GIS and the best place to bury materials. Achieving appropriate solutions to reduce waste production and any changes in its components requires recognizing the current state of the city, the function and dominant role of the city, the economic conditions and the social and cultural status of the citizens. Familiarity with culture, customs, livelihood, nutritional habits and literacy rate, and many other factors in this field is important and can be explored. The most important and first priority in the waste management hierarchy is the avoidance of production. Despite the availability of suitable standards and per capita ecosystems, the city of Cain did not have a suitable place to collect and dispose of and recover waste; according to the research of this research, the best location for waste disposal outside the city and the boundary between Khein and Khezri village It turned out
