| Abstract: | In order to provide scientifical basis for water and soil conservation in the Three Gorges Reservoir Area,based on the natural,social and ecological condition in The Three Gorges Reservoir Area.The comprehensive evaluating index system for it was built.The index weight was determined by AHP.The model was evaluated and grade 48 kinds of tree species.According to the method of optimum cut,3 grades were classified.It showed that 17 kinds of tree species such as Pinus massoniana Lamb.,Cyclobalanopsis glauca,Cunninghamia lanceolata（Lamb.）Hooketc.were the first grade,21 kinds of tree species including some arbor tree species and some non-timber tree species were the second grade,10 kinds of tree species including some non-timber tree species and all shrub trees were the third grade for water and soil conservation.The optional trees for each belt of protection forest system in The Three Gorges Reservoir Area were also proposed by authors. |
