摘要：Physica appearance of earth surface countinusely changes due to human activities as well as natural phenomena and consequences appear in both local and global scales. The issue is so important that trend of changes in area of rangelands has been considered as an high value index in the evaluation of rangeland sustainability. Sufficient knowledge on the subject, is necessary for implementation of a perfect management on land as a major source in agriculture sector. Current research carried out to investigate the trend of changes in land use. To study the land use in 1996, were used the map provided based on lands at satellite TM 1996 by Forest, range and watershed organization of IRAN. To provide land use map for the year 2011,image from satellite IRS (LISS-III sensor) were used. In this area, land use categories were separated as rangelands with different percentage of coverage, appearance of stone masses, orchards, cropped lands and residential areas. Result showed that most area is related to rangelands marked as R3 (with coverage of 5-25%). Residential areas, despite of minimum area under usage, had the maximum of increasing changes (around triple). Trends of changes in land use categories in 15-year period was determined in significance and non-significance trial using spss.16 software. Such results showed that among the factors investigated, increasing changes in residential areas is significant (p0.01).
