| 摘 要： | 以云南通海杞麓湖流域森林土壤为研究对象,分析了自然状态下森林土壤养分各指标含量与肥力之间的关系.结果表明:该流域土壤有机质含量基本上处于偏低、缺乏状态;全N含量比较高,速效P属于极缺乏水平.土壤肥力的主成分分析结果表明:该流域森林土壤的有机质、速效N、速效P、pH值基本上代表了土壤自然肥力的水平,对土壤肥力有正向负荷;速效K、C/N影响土壤肥力水平,对土壤肥力为逆向负荷. |

| Abstract: | The relationship between the fertility of forest soil in the Qilu Lake watershed in Tonghai County,Yunnan Province and the nutrient indices of the forest soil under natural status was analyzed.The following conclusions were drawn: The organic matter content in the soil of the valley was commonly low or very low.The total N content of the soil was comparatively high,while the available P content was quite low.The principal component analysis of the soil fertility showed that the contents of organic matter,the available N,available P and the pH value of the soil could basically represent the natural fertility of the soil,showing the positive load to the soil fertility.Whereas the available K and C/N ratio would also affect the soil fertility,showing the reverse load to the soil fertility. |
| Keywords: | lake on the plateau area Qilu lake watershed forest soil nutrient |
