The ecologic and geologic environment is very frail and the rocky desertification is very obvious（the desertification area is 28 320 km2）in East Yunnan. The continuous development of local economy is affected seriously. We use three grade standard to classify the rocky desertification. The landscape difference is obvious, enough to take control measures correspondingly. The rocky desertification region is gathered by several small desertification regions from the north to the south and the desertification degree in south is higher. The genesis of rocky desertification is that there is rocky desertification potential with geomorphic evolutional precess, that karst mountains are material base of rocky desertification and that the local natural geographic environment is the fundamental condition. The main factor of rocky desertification is fast population growth, unreasonable exploiting of land and industrial pollution. In some places, the natural factor is the main factor, but in other places, the artificial factor is the main factor.
