摘要: 选择疏勒河流域为研究区域,利用1990年TM、2000年ETM和2005年TM影像为信息源,应用地理信息系统和遥感技术,提取三期疏勒河流域土地利用信息,并对土地利用动态进行了分析。结果表明,近15 a来,疏勒河流域土地利用变化缓慢,土地利用格局没有发生显著变化;不同土地利用类型中,耕地面积和建设用地增加较多;林地、草地面积减少;水域在1990—2000年间减少,2000—2005年间增加;未利用地在1990—2000年之间增加,2000—2005年之间减少。

Abstract: Shule River Basin, a typical inland river basin in arid region of northwest China, was selected as the study area in this paper. Based on visual interpretation of TM images in 1990, ETM+ images in 2000 and TM images in 2005, the land use/cover databases at three times were established, and then Land Use/Cover Change (LUCC) was analyzed based on the geographical information system. The results showed that the land use/cover change in Shule River Basin wasn't significant, and the basic pattern of land use/cover in Shule River Basin didn't change. In details, the cultivated land and construction land enlarged obviously from 1990 to 2000, while the forest and the grassland decreased during this period. The water area decreased in 1990—2000 and increased in 1990—2000, while the area of unused land increased in 1990—2000 and decreased in 1990—2000.

Key words: Land use change, Shule River Basin, Remote Sensing
