本文选取与桉树生态、生物学特性和生长规律有关的10个气象因子,对福建省64个县(市)的数据作R型主成分分析,结果前6个主成分的累积贡献率高达90.9％;用这6个主成分作模糊聚类分析,分出三类;用这三类的均值与固定样本比较,作模糊相似优先比判别,可将福建省引种的尾叶桉、巨桉两种桉树栽培区划分为最适宜产区、适宜产区和一般产区。
In this paper, 10 meteorological factors related to the ecological, biological characteristics and growth of eucalyptus were selected to make R-type principal component analysis on the data of 64 counties in Fujian Province. The cumulative contribution rate of the first 6 principal components was as high as 90.9% ; Using the six principal components for fuzzy clustering analysis, divided into three categories; with the average of these three categories and fixed samples for fuzzy similar priority discrimination, the introduction of Fujian Province Eucalyptus urophylla, Eucalyptus two Eucalyptus cultivation area is divided into the most suitable producing areas, suitable for producing areas and general producing areas.
