Abstract :

Introduction and purpose: Land resources preservation is necessary to decrease environmental impact by human activities. There are various kinds of decision making methods to organize land resources preservation plans. In this study Fuzzy Simple Additive Weighting (FSAW) was applied for zoning parts of the study area which need to be preserved against any kind of land use. Materials and methods: At first, data collection was conducted and the effective criteria to decide preservation plans were defined and weighted based on verbal variables and triangular fuzzy number system. Finally, maps overlaid based on FSAW method for study area evaluation.  Results: final classification of the study area showed that land classes for high, medium and low degree of priorities to apply preservation measures occupied 35, 58 and 8 percent of the study area, respectively. Discussion and conclusion: The results approved that suitability of a land is classifiable for various types of land uses using FSAW. Also according to the results; central and southern parts of the study area were in most need for preservation measures since intensive uses of land were mostly concentrated in those parts
