Multiple Criteria Location Allocation of Green Spaces by using Land-use Suitability Analysis Method (Case Study: Arak)

Urban land use and its location has always been of interesting topics to scholars of the city and urban planning. So that the scholars always have tried to pay attention to base and surroundings proximity, compatibility and incompatibilities, utility and other factors, in location allocation of urban land uses. With the arrival of the computer age and development of geographic information systems, the possibility of attention to these factors and their effectiveness in the process of planning, is more than before. In this regard and in order to realization of consideration to these factors in planning, this study is trying to answer the following question, Among the areas with development potential in area, which one is more suitable for use in order to green land use? In this article which is applied in terms of purpose and is descriptive analytical in terms, of method, land-use suitability analysis, linear combination and Delphi methods, have been used. The finding of this article that obtained from overlaying analytical compatibility maps, the value of land, land ownership, functional radius, proximity to roads, passive defense, and crisis management and natural and geographical factors of Arak, indicate that, which one of the lands with development potential in Arak, is more suitable for use in order to green land uses. Also the results of this article showed that, the combination of multi criteria location allocation based on geographic information system and Delphi jury method, can be used as decision support system of location allocation of green land use and provide acceptable results.
