| Abstract: | Based on TM imagine and field investigation ,this paper analyzed the current distributed area (accounts to 70 693 hm~2、34. 1% of the total area of Dejiang county) and patterns of rocky desertification ,divided developing degrees of rocky desertification (the area of middle degree rocky desertification is more than 16% of the total area of Dejiang county) ,and studied its influencing effects on regional social and economic development such as cultivated area trends to decrease and contradiction between man and environment is sharp, surf ace potable water for man and domestic animals tends to reduce, and the drought and flood become more and more frequent, etc.., and detail explored the causes of rocky desertification of Dejiang county in Wu-Jiang basin. Finally corresponding proposals to harness rocky desertification were suggested. |
