Prioritization of urban green land suitability in the process of switching places with MCDM techniques

Urban green space is one of the most important urban land use which are known as citie's breathing's lungs. Since the main objects of urban planning are health, comfort and beauty; from citizens point of view locating the green spaces as one of the most important elements of urban environments, have great impact on desirability and amenities of space. Therefore special attention to spatial organizing of this landuse, is an important step in ensuring the welfare of citizens. Due to the multiplicity of standards in locating the urban green space, in the present study by selecting zone one of Tabriz city as a case study, the feasibility of TOPSIS model as one of the multi-criteria analysis technique (MCDM) has been tested in land suitability analysis in the site selection of urban green space process. In this study, after identifying the effective factors in location green space, the criterion maps generated and then have been standardized and weighted. In the final map, area's land has been classified for selecting the suitable site for green space. Results of applying the model in study area show that the model is outputted pixels from the model, have the optimal conditions in terms of the defined criteria. Thus use of practical techniques such as TOPSIS model and capabilities of GIS can help civil affairs authorities in allocating lands for the required land use in general and green space in particular.
