urban land use allocation modeling based on Land suitability analysis

Urban land use and its location has always been an interesting topic for urban planners. As experts have tried to focus on the context and surroundings proximity, neighborhood, compatibility and incompatibilities, utility and other factors. By the expansion of geographical information systems, it is possible to focus on these factors and their impact on the planning process for land use allocation. At the same time, many scientific efforts have been made to integrate these systems and multi-criteria decision-making methods in order to enhance their ability to support decision making. Methods used in this field have also been widely used in various studies; one of the most important applications of these methods in urban planning is to determine the suitability of each parcel for allocating urban land uses. In this article which is applied in terms of purpose and is descriptive analytical in terms of method, the land-use suitability analysis as a scientific technique along with linear combination, and Delphi methods, have been used. Findings, which have been obtained from overlaying analytical maps (land prices, access to communication axes, number of blocks of land and air pollution's maps), indicate that what type of land use is more suitable for each parcel. The results of this paper are presented in the form of land use allocation scenarios. Comparison of the results of modeling with current situation shows that out of 2,166 parcels in the study area, 521 have no suitable uses and need change.
