| Abstract： Taking satellite remote sensing data obtained in three different periods, i.e., MSS(1975), TM(2000) and SPOT-5
(2007) , as the main data, and using the technology of remote sensing image processing and information extraction, the
authors extracted the soil erosion information of Zhangjiajie City in three different periods and analyzed characteristics
and regularity of the dynamic changes from 1975 to 2007. In addition, some suggestions concerning the measures for
harnessing soil erosion are put forward in this paper. |
