摘要
以遥感信息判读为主要依据，拟定了土地沙漠化动态分类系统，在遥感影像上进行面积量算，获得了定边县从１９８０年到１９９３年土地沙漠化动态变化状况，说明定边县沙漠化程度得到了一定控制，对土地沙漠化的治理取得了明显效果。
Dynamics of soil desertification in Dingbian from 1980 to 1993 was revealed through analysis on remote sensing data in this area. The results showed that the soil desertification had been controlled to certain extent and the control effect was obvious.
