Spatial-local Suitability of Urban Green Space in Regional Scale in the Birjand City Regional Parks

Due to new urban development, there is no balance of green space and open space between urban networks and natural patterns and urban networks are dominating ecological networks. Therefore, cities are in need of urban revival. Because the presence of nature in cities is a necessity for sustainable development. Hence, optimal allocation of land to urban green space usage is one of the main responsibilities of urban and regional planners. The first step is land suitability analysis (i.e. identifying the suitability of a piece of land for a special and defined usage), because an appropriate site selection is the result of a correct suitability analysis. In fact, the purpose of the present study is to provide a method for spatial-local analysis of urban green space (in regional scale) with emphasis on combination of qualitative and quantitative factors (social factors (population) and physical (local and situational), on the basis of ecological principles and using multi-criteria evaluation in GIS to select appropriate sites for creating green space. Finally, this method is used for suitability analysis and site selection of regional parks in Birjand City. Based on, in general, state of regional parks suitability is acceptable. However, there is a significant gap between the current level and ideal level.
