ENVIRONMENTAL IMPACT ASSESSMENT OF URBAN DEVELOPMENT PATTERN ON MARGINAL AREAS (CASE STUDY: ZABOL CITY)
Abstract. Environmental assessment of urban development on marginal areas in Iran as an inevitable approach to assessing the degree of compatibility of this policy with sustainable urban development components seems to be necessary due to its wide impact on the ecology of cities in Iran. In this framework, the main objective of this article was to assess the environmental impacts of urban development on marginal areas in Zabol city. The research method in this research in terms
of research goal, is Applied, and in terms of the research framework, it is analytical and descriptive. SPSS and Expert Choice software were used to analyze the data. The results of single-sample T-test of the environmental indicators in the marginal areas of Zabol city, as well as the environmental impact on the marginal areas, showed that in all indicators, the average obtained is above the average of 3. In fact, the results show the environmental impact of the urban development pattern in the marginal areas of Zabol city is high. In the following, Spearman correlation test has been used to determine
the relationship between these two variables (Environmental impacts of developmental pattern and marginal areas). The results showed that there is a significant relationship between the environmental impacts of urban development and marginal areas, with a significant level of 0/00. Finally Expert Choice software is used to evaluate and rank the most important environmental impacts of urban development pattern on marginal areas from experts' point of view. The results showed, among the desired indicators, air pollution with a weight of 0.374, soil pollution with a weight of 0.220, water
pollution with a weight of 0.177, vegetation changes with a weight of 0.125 and noise pollution with a weight of 0.105 ,respectively, have the highest and lowest weights.
