摘要
本文运用组平均法、主成份分折法和主坐标分析法对宁波北仑山区２８个样地进行了分类，三种分类结果得到较好的统一，初步划分出７个群系与１０个群丛，建立了该地区森林植被的分类系统。
The numerical methods of group average, principal components analysis and principal axes analysis are used in this paper for classifying the 28 plots of Beilun Mountains, Ningbo. The results from these three methods are similar to each oter. The forest types are tentatively divided into seven formations and ten associations, so that a classification system for the forest vegetation of this area is established.
