Abstract

Industry growth and population increase in cities has led to utilitarian construction. In such constructions, the hygienic issues and supplying minimum air and light in dense urban areas have not been considered. Also the necessity of creating new urban usages for meeting the increasing trend of urban requirements and people housing has gradually reduced the green spaces and urban gardens, which has led to environmental pollution. Therefore this study was made to evaluate and optimal allocation of urban green space in order to achieve urban sustainable pattern in district No.11 of Tehran municipality. The research method in this study is a combination of descriptive – analytical method  and type of study is applied one .
Hence to calculate of per capita green space in the area, firstly by  using normal differential vegetation index (NDVI) related to the  data of ASTER sensor, the green space per capita was calculated 2.57 square meters, which is very low in comparing with the  minimum per capitas. Therefore AHP model was used to allocate green space. The results show that from 1205 hectare of ​​this area, about 195 hectares of land area equal to 16 percent of the total area of ​​the district were  fully compatible and consistent for expansion of green space . Therefore, the results of this study  can  help to urban planners to understand and prioritize urban issues and find solutions to solve these problems.
