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、恢复土壤资源及营林有实际指导意义。

Abstract

Ten environment indicators are selected as key factors influencing forest soil fertility characteristics in closure area by using the method o f main composi tion analysis. Forest soil fertility is divided into four types in closure area by the way of clustering analysis

and the classi fication result is checked up. On the basis of integ rate evaluation on four types of soil fertility

the measures of vegetation restoration and its management utilization direction are given as the different fertilty type. There are actual produce mea ning so fresearch result to reasonable utilization

soil resource restoratio n and forest construction.
