Abstract :

Land use planning is a science that specified the optimized use of land based on Ecological and socioeconomic characteristics it. In many parts of the Iran, the selection and management of land use is done regardless of land capability that it causes disinvestment and reducing the environmental capacity. This study are investigated ecological capability evaluation for development use by GIS in Jahrom township of Fars province. There are different methods to weighting of various parameters. For this purpose in this research, a quantitative method is proposed to weigh criteria and their evaluation that compared with the current method of multi-criteria evaluation (MCE). In relation to common method of multi-criteria evaluation, it was used weighting approach based on improved Analytic Hierarchy Process (M-AHP). The next step was to evaluate the performance of each of the mentioned models throughout error matrix. Results showed that the proposed method of Regional Weighting (RW) in MCE models has higher capability than MCE (M-AHP) to estimate the ecological potential of study area. Overall, Results showed that the proposed method of Regional Weighting (RW) can be replaced to common methods of Weighting due to Simplicity, No need to questionnaire, save time and cost.
