Locate and Prioritize potential sites to physical development using hierarchical approach (TOPSIS) and Geographical Information System (GIS) (Case Study: Daryon City)
Abstract:   (23505 Views)

The world in which we live is constantly changing. Factors affecting transformation and changing of phenomena and terrain can be divided into two categories: natural and human. Natural and human phenomena have important role in the location and physical development of cities. Considering that in the past, urban locations were limited to human and social studies, it is necessary in addition to these studies we pay special attention to geomorphological research and physical environment of cities. Since the geomorphic and topographic features of a geographical place are not only responsible for dispersion or aggregation of human activities, but also are considered one of the factors influencing the shape and spatial structure, neglecting these factors cause to incur huge losses to cities, and the development of cities and settlements will be made in such a way that natural and ecological constraints prevent the continuation of activities and in practice, many of investments will be wasted. In other words, if a land is used according to its capabilities, then suitable urban development will be assured. Accordingly, identifying potentials of a territory before establishment on it and loading land uses and urban activities is very important. Thus, since maintaining a balanced and harmonious physical combination of city requires proper planning and management, these reasons led us to conduct the research to find suitable potential areas for future development of Daryon City using TOPSIS model and affecting factors such as landuse, distance from main roads, distance from the river, distance from the city, distance from the village, geology, soil, elevation, slope and protected areas and after appropriate weighting to criteria, it was determined the importance and place of each criterion. Finally, after overlapping the layers, it was obtained 5 regions among which about 62 percent equivalent to 93542.5 km are in classes with high and very high proportion. Therefore, it was found that except an area less than one third of the region, other areas in this city are not faced with major ecological limits.
