摘　　要：利用样地比较的方法 ,从物种多样性、地上现存生物量、主要饲用植物生物量、群落光合生产结构、优势种、群落密度、生境等多个角度 ,研究在皇甫川流域三种不同生态环境类型下的草地群落的特征 .结果表明 :原生环境区的群落结构优于生态恢复治理区和水土流失区 ,各方面的指标大都好于后两者 ,水土流失区群落状况较差 ,生态恢复治理区的群落状况居中 .The paper studies the characters of grassland community in three sites with different ecology environmental types in Huang Fuchuan Watershed, including species diversity, above ground standing biomass, chief forage plant biomass, structure of community photosynthetic productivity, dominant species, community density, habitat. The results were as follows: The community structure of Primary environmental region was superior to that of Ecology restoration region and Soil and water loss region, all indexes were almost better than that of other regions .The community structure of Soil and water loss region was the worst in three regions.
