After preparing sub-basin boundary, the process of digital and aerial images was conducted by Microstation, Erdas, ArcGIS and Autocad. Then, area alteration of arable lands, residential places and roads were compared during the four periods. The results have shown that the most area alterations raised in the first period from 1966 to 1994 as conversion of ranges and forests to arable lands.
