Zoning the possibility of developing natural recreational areas in Kohmareh-Sorkhi, Shiraz City using Analysis Hierarchical processes and Weighted Liner Composition
Today, ecotourism has a special situation in the world. As most countries have included it in their economic, social and cultural planning, and because of its many benefits, each country has launched extensive publicity to introduce its attractions. In this study, in order to allocate lands for ecotourism development, a multi-criteria evaluation method based on the process of hierarchical analysis and weighted linear composition in Kohmareh Sorkhi region of Shiraz city was used. Ecological criteria including land use, soil depth, and distance from the village, height, direction of slope, slope, distance from river, and distance from road were used. Then, according to previous research in this field, priority was given to prioritizing important variables in terms of the importance of zoning for tourism development, and each layer was weighted using hierarchical analysis. In the next step, constraint layers such as (slope, distance from the road, village and river) were constructed using Boolean logic. Then the desired layers in Idrisi software were identified by linear weighting method and using hierarchical analysis weights and constraint layers, suitable areas for ecotourism. Slope criterion with a weight of 0.32 had the highest weight and was the first priority in the ecotourism. Also, land use with a weight of 0.22 was in the second priority and distance from the village with a weight of 0.15 was in the third priority. The final Zoning map of tourism potential areas by linear weight combination method showed that it is very suitable with an area of 2336 hectares, 4% of the area, suitable with an area of 11527 hectares, 19% of the area, somewhat suitable with an area of 32745 hectares, 54% of the area and unsuitable with an area of 14320 hectares, including 24 percent.
