Comprehensive Discussion on Low-function Ecological Forest Reconstruction Technology of Cunninghamia lanceolata and Pinus massoniana in Anhui Northern Subtropics Region

The causes for lower ecological benefit of pure coniferous forests were analyzed from many aspects such as biodiversity,soil conservation,net primary productivity,and so on.And,these Cunninghamia lanceolata and Pinus massoniana pure forests could be reconstructed into conifer-broadleaf mixed forests which have higher ecological benefit,if we take follow measures: intermediate cutting,closing mountain,replanting broadleaf trees,and so on.
