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15a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。
In order to select the Shulehe River Basin as the research area and use the 1990 TM, the 2000 ETM and the 2005 TM images as the information source, the Geographical Information System and the remote sensing technology were used to extract the land use information of the Shule River Basin in the third period. The land use dynamics Analyzed. The results showed that in the recent 15 years, the land use change in Shulehe River Basin was slow and the land use pattern did not change significantly. Among the different types of land use, the cultivated land area and construction land area increased more; the area of forest land and grassland area decreased; Decrease in the years, increased between 2000 and 2005; unutilized land increased between 1990 and 2000 and decreased between 2000 and 2005.
