摘 要：
采用ＰＣＡ多元分析方法，以植物种在草地群落中的数量特征为参量，对放牧干扰梯度上的依赖植物集团（ｇｕｉｌｄ）进行了初步划分。研究的草地群落有羊草（Ｌｅｙｍｕｓｃｈｉｎｅｎｓｉｓ）—杂类草群落、羊草群落、贝加尔针茅（Ｓｔｉｐａｂａｉｃａｌｅｎｓｉｓ）—羊草群落、贝加尔针茅群落和贝加尔针茅—线叶菊（Ｆｉｌｉｆｏｌｉｕｍｓｉｂｉｒｉｃｕｍ）群落等５个类型。结果表明，植物种在放牧干扰梯度上可划分为三大类群，即：优势种—喜牧种植物集团、杂类草植物集团和耐牧适牧种植物集团。少数种类表现不明显呈离散关系态。

摘 要：
The guilds of grassland communities were preliminarily studied along the gradient of the grazing disturbance, using the PCA polythetic analysis method through the characteristic parameters of the communities. The grassland communities studied were Leymus chinensis herbage community, L. chinensis community, Stipa baicalensis L.chinensiis community, S. baicalensis L;chinensis community, S. baicalensis -Filifolium sibiricum community. The results showed that the plant species along the grazing gradient were divided into three groups, closing the dominant and like grazing species guild, dicotyledon herbage guild and endurable grazing species guild, while a minority of species should the situation separated from one another.
