| Abstract: | After Wenchuan earthquake, the disasters such as vegetation destruction, soil erosion, the secondary geo-hazards and so on has great impacted on ecological environment in the disaster area. Taking Wenchuan County as a typical region, this paper applies the 3S technology to quant/tatively evaluate the ecological environment before and after earthquake and its change. The influence of the earthquake on ecological environment of Longmen Mountain was analyzed to provide reference for post-disaster reconstruction. |
