摘    要:本文运用逐步回归分析方法,筛选出土壤肥力评判因子。引用Fuzzy集合理论进行综合评判。通过建立隶属函数,根据最大隶属原则,确定部分立地类型土壤肥力等级。为造林选地,森林经营设计提供科学依据。

关 键 词:土壤肥力  综合评判  逐步回归  Fuzzy集合  隶属函数

Abstract:By means of stepwise regression analysis, the judgment factors on soil fertility were deter mined and these factors judged on forest soil fertility the with theory of fuzzy sets. Based on the principle of maximum subordination, where a subordination function was established, the classes of soil fertility of major site types were differentiated and provided a basis of selecting lands for plantation and arranging forest working groups.
Keywords:Soil fertility  Comprehensive judgment  Stepwise regression  Fuzzy sets  Subordination function
