Investigations on the forest communities were done in the Baiguo
primeval forest, Hongchiba afforestated forest and Wenfeng
artificial restorated forest in Wuxi County. The results were as
follows: 1) The rare and endangered plants were pretected well and
became the dominant populations in the primeval forest of Baiguo;
2)In Hongchiba, the Pinus
aemandii forests were afforested by flying sowing. But because
of the great vitality of the native trees, the mixed forests were
formed by the native trees and Pinus aemandii; 3) The forests in Wenfeng town were planted
artificially, and had the single tree , simple structure and week
resistance to disturbtance. The corresponding strategies were put
forwards according to different communities, which would be the
scientific basis for the practice of water-soil conservation and
ecological restoration in Wuxi county. Key words:
ecological restoration; water-soil conservation; Wuxi County/Chongqing
