基于遥感的鄂尔多斯农牧交错区生态环境变化研究

Research on Change of Environment in Ordos by Remote Sensing

鄂尔多斯地区是农牧交错带中段的典型地段,生态环境十分脆弱,土地沙化问题严重.对鄂尔多斯市生态环境近遥感监测的结果表明,1990～2003年的十三年间鄂尔多斯市8.60%的环境地物发生了变化,主要表现为土地沙化过程和草地退化过程.

Ordos is the typical region of the ecotone between agriculture and animal husbandry in the North of China. The environment here is terribly vulnerable, and is faced with the severe process of degradation. After monitoring to the environment of the city of Ordos by remote sensing, the main results are as follows： 8. 6 percent of environmental features had been changed form 1990 to 2003. The changes mainly represented the desertification and pasture degradation.
