Study on Soil Anti-erodibility of Plant Community of Secondary Succession in Jinyunshan Mountain
The typical and representative plant communities of different stages of succession were chosen in Jinyunshan mountain of Chongqing for vegetation investigation and soil anti-erodibility analysis. Three kinds of co-factors were suggested, which could reflect most information (89.2% ) of characteristic root, and then with the corresponding variance contribution rates of the 3 kinds of co-factors as weight numbers, the integrated scores of 10 plant populations in soil anti-erodibility were calculated out. Among them the soil anti-erodibility of initial community was best, that of top-grade community and anaphase plant community of intermediate form was secondary and that of pioneer forest was worst.
