摘要: <正>本文介绍国内外关于多元分析方法(包括多元回归,判别分析,聚类分析,因子分析和典范变量分析等)在森林土壤学中应用的事例。 在我国,多元分析在土壤学上的应用始于七十年代后期。一开始就有一些定量和数值化研究工作是与森林土壤及其水分状况分类、森林土壤生产力评价和森林土壤障碍性因子诊断等课题有关。例如,对东北地区灰化土与暗棕壤的判别,用模糊聚类法进行华北褐色森林土的数值分类,用系统聚类法将南京附近杉林下黄棕壤的湿度状况进行归类,对江西省杉林下土壤障碍性条件的判别分析,以及用多元回归对南方杉木林或其他树林下土壤生产力的评价,等等。

Abstract: An account on the application of multivariate analyses to forest soils, including multiple regression, discriminant analysis, cluster analysis, factor analysis and canonical analysis thar have been used by domestic and foreign researchers, is made here.In China, the use of multivariate analyses to soills began in the late seventies. From the very start, research efforts on quantitative and numerical matters have been made in combination with the classification of forest soils and their moisture systems, the evaluation of the productivity of forest soils, and the diagnosis of forest lands with inhibiting soil factors. Major investigations made so far include: the discrimination between podzolic soil and dark brown forest soil in Northeast China, the numerical classification of drab forest soil in North China by fuzzy cluster method, the grouping of moisture regimes in yellow brown soils under Chinese fir plantations near Nanjing by hierarchical clustering, the discriminant analysis of the inhibiting soil conditions of Chinese fir stands in Jiangxi Province, the evaluation of productivity of the soil under Chinese fir and other tree species in southern China by multiple regression and other methods.
