- Abstract:
-
Because of serious soil erosion, the ecosystem in the loess plateau is in an extreme degradation condition. There are important theoretical values and practical meanings to disscus the change of plant diversity during natural recovery process of vegetation succession. The natural recovery and distribution pattern were investigated in Caijiachuan closed watershed in the loess plateau of western Shanxi using line transect method and sampling plot method. Based on hierarchical cluster analysis and succession analysis, the present paper deals with community types and community vegetation succession. The results show that vegetation cover degree of watershed and species diversity increased greatly along the succession process. The major plant association is one whose dominant species is Pinus fabulaeformis, as climax biotic community of this area.
