Abstract

In the present age green space is considered as one of the indicators of sustainable development due to its importance and its role in the life and development of cities. The physical and natural effects of these spaces in the urban system and its various ecological, social, and economic returns are
indisputable in the structure of societies. As far as the use of green space in cities and its per capita is considered as the main issues in urban planning and management. The purpose of this research is to evaluate the environmental quality in Tehran 10th District based on available green space and provide appropriate recommendations for improving the quality of the environment to the standard level. To reach this goal, green areas were extracted using Landsat-8 satellite image and NDVI (Normalized Indicator Index). The areas of green space extracted with air quality indexes and population density and using the indexing index method at each block level were quantitatively analyzed to determine the relationship between these factors. To identify areas with high sensitivity, the map of the state of the environmental crisis was created based on population density and available green space. The results indicate that 3.25% of the total area is covered by green space, as well as 122 blocks out of 125 without the minimum per capita green space for healthy living. In order to raise the quality of environmental indicators to international standards, recommendations for areas where green space should be created are presented. This research is important for future development projects, urban planning in order to maintain environmental quality at an acceptable level.
