南方速生丰产林基地划分的探讨

Division of Fast-growing and High-yielding Forest Bases in the South of China

本文采用了主成分分析、聚类分析等方法,在南方12省、区内划分了18个速生丰产林基地,用判别分析建立了各基地的判别函数式,回判准确率在99％以上。本文还就各基地的水热状况提出了可能生产力。

On the basis of principal component analysis and cluster analysis, 190 counties in the south of China have merged into eighteen fast-growing and high-yielding forest bases. The method of discriminant analysis was used for giving discriminant functions to bases and had 99% accuracy. Primary productivity was calculated from temprature and precipitation of 18 bases.
