Abstract :

Physical development of Kamyaran city and how to deal with various natural and geomorphic units, including hills, rivers, old alluviums and fault lines have brought important issues and challenges. This study seeks to identify factors influencing the location and development of Kamyaran and regarding these factors provide an appropriate model for the future development of this city. This study is applied and descriptive-analytical research in term of objective and method, respectively. In this study field observation, aerial photos, satellite imagery (Landsat) and DEM 27 meters were used to extract much of the information and maps in the GIS software. Data sets were examined and analyzed in Analytical Hierarchy Model. According to the results, almost 33% of the Kamyaran current limits were built in areas with optimal fit. Lands with the proportion of medium and low fitness are in next priority, correspondingly. Constructed parts of the city on the foothills Pir Mohammad and its surrounding areas, around Kamyaran river and Hassil Qader creek, as well as Gla Charmo and the hills in eastern part of the Kamyaran River, where phase 3 of Be'sat county and some parts of phase 1 has been constructed, all together show the ignorance of natural factors. The reason for this situation further is due to the willing of land owners and the interests of early migrants to settle on the roadside to their migration origin. Finally, it should be noted that based on the analysis of hierarchical model, within 34 square kilometers which was considered around the city, nearly 29 percent of its area, has high and very high proportion for development, which are located in the Northeast, Northwest, West and Southwest of the current position of Kamyaran city.
