| 摘 要： | 2002年,应用RS、GIS高新技术遥感手段和美国大型图像处理软件ERDAS,对全盟生态环境现状进行1996年、2000年、2002年度定量动态对比监测;应用arc/info v8.0建立生态环境现状本底数据库.定量动态对比监测GIS数据结果显示:阿拉善盟沙尘源区域荒漠化问题继续存在,沙漠、戈壁面积在继续增加,草地覆盖度下降,导致地表裸露程度增强,沙尘源物资增多,草场生产力不足;梭梭林面积减少,乔木林演变为灌木林;腾格里沙漠和乌兰布和沙漠扩大速度较快;动态分析表明沙漠治理速度尚赶不上沙漠扩大速度,全盟"握手"沙年度间呈较快扩大趋势.

| Abstract: | In 2002, the status quo of ecological environment of Alshan League was studied with RS and GIS high and new technological sense - remoting tool and large type image treatment software ERDAS of USA, based on the quantitative and dynamic comparison of monitoring data in 1996, 2000 and 2000. The background database of ecological environment status quo was established with arc/info v8.0. The dynamic analysis showed that the speed of desert treatment could not catch up with the speed of desert expansion, the hands - shaking sands of whole League took quick expanding tendency. |
