| 摘 要： | 准确把握土地沙漠化动态对沙漠化治理具有重大现实意义。本文介绍了地理信息系统（GIS）在沙漠化化动态监测中的应用和遥感图像计算机监督数字化分类的理论和方法，对遥感图像计算机监督分类的精度做了检验。对调查区土地沙漠化动态进行了分析。结果表示，从1991年到1997年间该区土地沙漠化趋势有所减弱，综合治理取得了一定效益。

| Abstract: | This article introduced the theory and methods of satellite image automatic supervisng digital classification by computer and the application of remote sensing and GIS in the dynamic monitoring of desertification.The dynamic of desertification of research area was anglyzed.The result showed that from 1991 to 1997,the area of desert decreased 3 938 hm2,the tendency of soil desertification of this area had weakened.Comprehensive administer has been gained.Some good results have been achieved after integrated management. |
