Abstract:
Because disturbances from the Wenchuan earthquake to the regional environment are very huge and continuous,disaster controlling and recovery of ecological environment in disaster areas is an important task of rehabitation.By means of expert scoring method,the evaluation index system of vegetation restoration was set up in the Wenchuan earthquake zone.And studies were made of recovery characteristics of community,biomass and soil from typical damage forest of representative 9 counties in Wenchuan earthquake areas through the way of sample plot.On this basis,the disaster types and the degree of forest land damaging caused by the earthquake were evaluated,and some vegetation restoration models were screened out in view of different disaster types and at different degree of forest land damaging.
