Presenting an Optimal Green Space Model Regarding Sustainable Urban Development Indices

The concept of sustainable development is based on generating a balance in environment and in terms of spatial , the cities are the most important intersection of human and environment. Therefore, attention to the urban lifestyles and planning, in order to establish ecological balance in cities is essential for sustainable urban development. Among the 10 districts of Tabriz metropolitan, zone 8, due to historical, cultural, heritage and tourism is one of the most strategic and important areas. The district's location as the central tissue of Tabriz, has doubled the importance of expansion of green spaces and urban parks. Present study is an Analytical-descriptive research, which has been provided by the functional nature. This study has attempted to present an appropriate pattern of spatial arrangement of urban green spaces in the study area with respect to parameters of sustainable urban development using a combination of capabilities of GIS and TOPSIS model. In this research, after selecting the effective criteria and weighting them, by combining these criteria using TOPSIS model which is compensatory model in multi-criteria decision systems, the optimal places for the use of green spaces in district 8 of Tabriz Municipality was selected. According to TOPSIS model’s output map and comparing it with land-use map of the study area, it was found that the suitable land for creating green spaces are in large proportion of land use. In the following ,according to the high air and noise pollution in the study area due to its central location in the city, proper native species has been introduced to prevent air and noise pollution. The use of native plant species and proper planning of urban green space will cause the diversity, beauty and improve the ecological environment and ultimately will also bring the environmental sustainability of cities. Therefore planning to create a sustainable green space in this area to achieve a sustainable urban environment is essential and this planning must be led toward the direction which followed Stability and costs reduction.
