Locate parks and urban green space use Geographic Information System Method AHP multi-criteria evaluation (Case Study Area of Tehran)

Urban green spaces as an integral and essential component in the metabolism of the body of cites one of them is capable of Major Role. The lack of them can cause serious damage to urban life. The results show that urban green spaces have social and ecological efficiency.

Then, for each of the factors affecting the location of parks, green space, information layers in GIS environment was prepared and for each of the layers was conducted weighted. Then, to modeling, to each layer of information based on their importance locate parks and green space has been reclaimed using appropriate weight AHP model According to the map of places that are rated higher, such as wasteland and open spaces close to the cultural and educational centers have higher priority.
