| 摘 要： | 在重庆缙云山选择典型、有代表性的不同演替阶段的植物群落,进行植被调查和土壤抗蚀性分析。通过因子分析,提出了可反映特征根大部分信息（89.2%）的3类公因子,并以3类公因子对应的方差贡献率为权数计算出10个植物群落土壤抗蚀性的综合得分。其中先锋群落的土壤抗蚀性最好,顶级群落和过渡类型后期植物群落的土壤抗蚀性次之,先锋森林的土壤抗蚀性最差。

| Abstract: | 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... |
