摘要
以两个时期遥感信息解译为主要依据，拟定了土地沙漠化动态分类系统．采用面积连续清查方法，在两期遥感图像上进行成数抽样，获得了盐池县从１９７６年到１９９１年土地沙漠化动态变化状况，说明盐池属于正在发展的沙漠化地区，沙漠化程度进一步加剧，对土地沙漠化的治理与破坏同时并存。
On the basis of two periods remote sensing information explain,drawed up the developments classification system of desertize of soil. Use the method of successive check area,on two periods remote sensing phototakesample. To gain the condition of desertize of soil from 1976- 1991 of Yanchi county. It shows Yanchi county is developing desertize area,desertize level intensifier than before. Adminster and destroy at the same time exist to desertize of soil.
