摘要
通过主成分分析选出 10个环境指标作为影响封育区森林土壤肥力的关键因子 ,采用聚类分析法将封育区土壤肥力划分为 4个类型 ,并对分类结果进行了检验。在对 4个土壤肥力类型综合评价的基础上 ,提出了不同肥力类型的植被恢复措施及其经营利用方向。其分析结果对合理利用。
Ten environment indicators are selected as key factors influencing forest soil fertility characteristics in closure area by using the method of main composition analysis. Forest soil fertility is divided into four types in closure area by the way of clustering analysis, and the classification result is checked up. On the basis of integrate evaluation on four types of soil fertility, the measures of vegetation restoration and its management utilization direction are given as the different fertility type. There are actual produce meanings of research result to reasonable utilization, soil resource restoration and forest construction.
