Abstract
Based on the statistical data and three TM images in 1990, 2000 and 2008, and using the technology of GIS and RS, the land use change and its driving forces in Kashi in the past 20 years were analyzed. The results showed that:in the past 20 years, the single landscape types changed obviously. Along with the farmland and residential land increasing, the grassland and unused land decreased. The fragmentation and separation varied, owing to the natural and human disturbing. The artificial landscape tended to be stable and complicated, however the structure of natural landscape was simple and fragile. The dynamic degree of land use underwent an "obvious change-slow change" trend. The whole landscape fragmentation increased, and the shape became more complicated and irregular, and heterogeneity and relevancy are enhanced. During the study period, the land use degree was still very low, but increased sustainably. The informing entropy underwent a process of "order-disorder-order" change. The driving forces denote: the landscape types that can bring high revenue are disturbed more easily by human beings, while the natural landscapes are disturbed more by natural condition.关键词
