Abstract :

Spatial planning is the distribution and organization of activities in the area. In origin the space program, planning the physical structure and activity planning level. the first step in macro-level planning process to determine areas is planned as homogeneous units. the aim of this study was to determine homogeneous areas planned in Tehran with an emphasis on urban and rural planning system is in this metropolitan area. type of study is applied and the method is descriptive - analytical. in this paper to determine thehomogeneity regions of the 3 basic criteria: the built environment, socio-economic environment and the natural environment with the total of 22 indices (items) are used. planning for the homogeneous regions of k-mean clustering method is used. Clustering techniques include the use of multivariate data among groups or clusters of that, of course, on the basis of homogeneity among the objects are the same as those in the group are very similar. to perform clustering, layers (index) after processing, switching and computing environments Arc Gis software and Matlab, for 4 base area and homogeneous planning in the form of maps showing the boundaries of each of the zones identified and strategies were presented to each .
