| 摘 要： | 从土壤的理化因子出发，利用综合评价的方法，建立土壤肥力综合指标模型，对四川盆地西缘山地土壤的肥力状况进行了研究。结果表明，该区域内影响土壤肥力的主导因子为土壤有机质的含量、全氮重、全碳重及代换性H^ 含量。在同一种土壤类型中，随着植物群落的演替土壤肥力逐渐增加，但这不适合于不同土壤类型之间。这是由于不同的土壤类型所对应的气候条件不同所致。

| Abstract: | Based on the physical and chemical properties,a comprehensive evaluation index system was developed.With this system,the integrated fertility of mountain soil in the west of Sichuan basin was studied,Which suggested that the dominant factors effected IFI were soil organic matter,total C,total N and replaced H~+. In same type of soil,with the succcession of plant communities IFI increased.But this was not the case in different types of soil,for the different types of soil mean the difference of climate conditions. |
