摘要
系统聚类分析法已被广泛地应用于植物群落分类、演替阶段划分等研究中。本文采用六种聚类分析法将松嫩平原南部羊草草地划分为轻牧、适牧、重牧、过牧和极牧五个放牧演替阶段,其结果与野外实际调查基本一致。
Six cluster analysis methods have been used to divide the successional series of grazing Aneurolepidium chinense grassland in the south of Song-Nen plain. Based on the results of cluster analysis, the grazing successional series is divided into five stages, namely lightly grazing, properly grazing,heavily grazing, over grazing and extremely grazing. The results is consistent with those investigated in the field.
