Extended AbstractNumerous meetings of international and regional levels in the environment at the global level as well as the World Cup's concerns in this regard reveal. The overall objective research Identifying indicators of environmental conditions in the areas of Tehran will be. The method, manner Analytical Descriptive Is. With the participation of experts indices of me without scoring and with Analytical Hierarchy Process And Software Export Choice Will be weighted and then using statistical methods to calculate, and then software Arc Gis Will be drawn. The method of collecting data through inquiries from relevant agencies and has been interviewed. According to studies conducted in 22 districts of Tehran rating obtained by evaluating environmental performance index between 49.2 to 72 is obtained and thus 11 of Tehran province in appropriate zones, and 11 are appropriate area in the zone. Introduction Assessment Stability Life Environmental The situation Available, To the subject The most important Tool At Process Development planning Stable Able Plan And Check Is. This Assessment, An evaluation Habitat Cognitive Is That At Levels Different To Successively carried out and To Follow Presentation Framework Is That In its impact assessment of programs, strategies and policies on the environment comprehensively assessed, measured and analyzed. Finally, strategies for reducing pressure on the environment. Prepare the environment Appropriate Direction Assessment And Measurement Stability environmental At Process Planning And Development To Special Urban development Necessary And necessary Is . Assessment Amount Stability Reflect and increasingly as the most important measure Tool Direction Change Conditions At To Development Is stable. At country We process Development Hastily And No planning And Remarks Bio Environmental Urban centers, especially Tehran With Vector shares From References, Destruction Marginal lands, gardens, Forests, create Incompatible land uses And At Finally, pollution Water, Air and soil In Level Widespread On Face Spaces City Can be seen That Cause Eat the balance Natural ecosystems By Is. Growth Irregular Tehran At Decades Recently, Disorders Structure Important At Perspective natural And City To Follow Have Is. Materials and Methods The research method, Adherence From nature Question, Way Analytical Descriptive That by using statistical and mathematical data will be analyzed. Data and information required by official statistics agencies and subsidiaries of Tehran Municipality is collected. Scoring each indicator on the environment and affecting performance scores range from 1 to 9 that what is done and the experts preference among the indicators of the interviews and sat on the index of scores, and the total have expressed by applying coefficients of each of the four sectors indices are obtained. In order to incorporate the information model that used in the original model based on the weight of the model (AHP) is. Index through Expert choice software for a couple of levels compared to the relative weight of each round and at the end all criteria specified in the environment, and the model Arc GIS software, base of needed the analysis will be presented. Results and findings Zone 4 has a disadvantage in terms of waste management indicators so that this area has received the highest rating (1.6) and in the regions 9, 21 and 22 with a score of 5.2 has been more favorable terms than other areas because this area very high and consequently the population over the region compared to other regions is 4. The minimum and maximum scores of plants and biodiversity in urban areas fluctuated between 1.3 to 8.5 and in these connection areas 8, 10, 11 and 17 had the least amount of vegetation and biological Tnva and the only district 22 with a score of 8.5 with the most vegetation and biodiversity is appropriate. In connection with the construction and use of the fifth with a score of 1.1 is not appropriate circumstances, i.e. the amount of construction in this area is high and the User's had only a small according to these indicators region with a score of 3.5 in 8 is suitable. Climate change and energy index from 13.1 to 22.8 has been the 10, 13, 15 and 20 with a score of 13.1 in uncomfortable positions and Region 2 with a score of 22.8 was the only region that has achieved the highest rating. One of the most important indicators in assessing the environmental performance index of soil and water resources is the index value mentioned in the case study ranged from 17.3 to 41.9 and the region 20 has the worst the regions 1 and favorable conditions twenty-two are. In connection with the air quality index in the index of 31 to 42.4 is the worst air quality in areas 3, 7, 10, 18 and the best quality in zones 2, 5, 8, 13, 14, 15, 21 and 22 are confined to the relatively better performance areas that have been studied on the fringes of the city center have been established. The sound quality index of 2.2 to 8.2 were 6, 9, 10, 11, 12, 13, 15, 16, 18 and 19 of the worst performing regions 7, 8, 20 and 21 have outperformed other areas Tehran are generally urban areas in terms of sound quality indicators and standards do not have the right conditions. Conclusion It can be environmental issues in Tehran to radically divided into several categories in the First Division with the problems we face as a result of the geographical location of Tehran and the position of the weaknesses of the situation specific Geomorphic, and the difference high altitude between North, south and reducing the air flow direction and lack of capacity in its geographical location it has been exacerbated by the effects of weakness. The second class of environmental problems and urbanization process accelerated in Tehran and physical changes of the body. The third category of Tehran to the role of socio-economic issues that are concentrated in the city and at the end of the fourth Category From problems And Difficulties Environment City life Tehran Related To Structure Organizational And organizational Unsuitable for Management Metropolitan Tehran Is. Key words: Tehran, environmental performance indicators, sustainable development, environment. |
