巢湖泥沙淤积对环境影响的遥感调查与监测

Remote Sensing Investigation and Monitoring of the Impact of Chaohu Lake Siltation on the Environment

利用1955～1998年获取的航空照片和1973～2001年获取的MSS、TM、ETM多时相卫星遥感资料，调查分析巢湖泥沙淤积情况及其对环境的影响。应用不同时期遥感图像的解译结果，阐述了巢湖淤积现状、泥沙淤积来源及巢湖泥沙淤积厚度分区。利用不同时期成像的遥感资料对比，分析巢湖演变趋势并提出巢湖恢复治理建议。

In this paper,the sedimentation in the Chaohu Lake and its impact on the environment were investigated and analyzed by using the multi -temporal airborne remote sensing data acquired from 1955 to 1998 and satellite remote sensing data（MSS,TM and ETM） acquired from 1973 to 2001. The present situation of the sedimentation in the Chaohu Lake, the source of the sedimentation and the thickness partitioning of Chaohu sedimentation were analyzed by using the interpretation results of remote sensing images acquired in different periods. On such a basis, the evolution trend of the Chaohu Lake is analyzed, and some suggestions concerning the restoration and harnessing of the Chaohu Lake are put forward on the basis of a comparison of remote sensing data acquired in different periods.
