Abstract:: There is a large proportion of low-quality and benefit forest in Project of Natural Forest Resource Projection in Guizhou province, the improved effect of low-quality and benefit forest directly affects the quality of Project of Natural Forest Resource Projection. The growth of three working-groups of closed tackling and reconstruct, closed tackling and thinning, closed tackling and forestation low-quality and benefit forest were investigated and the diversity index was analyzed. The result showed: the number of species and individual were increased, the trend of forest structure is more equality, dominant species are Cunninghmia lancelata, Sassafras tsumu, but large numbers of target species had grown into the layer of arbor. The species and number of shrub reduced, dominance descended, and miscellaneous shrub lessened, target species increased, the whole forest structure are changing to mixed forests.
