摘要
地表植被的覆盖状况与水土流失强度等级之间有十分密切的相关关系，本文通过深入分析卫星数据的植被指数特性和规律，提出了根据植被指数确定水土流失的强度等级和分布范围的有效方法，通过在浙江新昌回山地区的试验，取得了很好的效果．
There are very close relationship between soil erosion intensity and ground vegetation cover density.According to the n-space spectral indices feature in remotely sensed data,the method to fast detect soil erosion intensity information based on only remotely sensed data was proposed.There shows a very good effect after using in the study area in XingCang County,Zhejiang Province.
