Abstract: Using the cluster analysis method and studying 16 sampling plots of shrub grassland where Bothriochloa ischaemum is the dominant species,and the plots’ grass frequency,grass coverage,density,height,and biomass,we graded the plots into five grazing stages;light,proper,moderate,serious,and extreme.Bothriochloa ischaemum is the dominant species in all the plots,while the other species flourish or decline successionally at different grazing stages.

Key words: Grassland science, Bothriochloa ischaemum, Shrub grassland, Grazing

摘要： 在对放牧利用下的白羊草灌丛草地频度、盖度、密度、高度、生物量等数量特征调查基础上,运用系统聚类分析方法,可划分为轻牧、适牧、中牧、重牧和极牧五个阶段。在不同的利用阶段,白羊草种群都是优势种,而其他植物种则呈现不同的趋势。
