| 摘 要： | 通过对青海湖北岸山地干草原群落特征及物种多样性的分析,结果表明:可将青海湖北岸芨芨草Achnatherum splendens草地、弃耕地、山坡草地和零星分布芨芨草的草地划分为4种群落类型:芨芨草+早熟禾Poasp.群落、早熟禾+垂穗披碱草Elymusnutans群落、艹洽草Koeleria cristatum+西北针茅Stipakrylovii群落和西北针茅+垂穗披碱草群落。植物多样性指数变化为:Shannon-Weiner指数和Simpson指数变化的大小顺序是滩地山坡草地弃耕地芨芨草草地,Pielou均匀度指数变化的大小顺序为山坡草地弃耕地滩地芨芨草草地,丰富度指数大小顺序为滩地弃耕地山坡草地芨芨草草地。生境条件的差异导致了物种多样性的形成。

| Abstract: | Through the analysis of community characteristic and species diversity of mountainous steppe in Qinghai Lake,this paper concluded that Achnatherum splendens grassland,abandoned land,mountain slope grassland and scattered A .splendens grassland were divided into four community types such as A. splendens+Poa sp.,Poa sp.+Elymus nutans,Koeleria cristatum+Stipa krylovii and S.krylovii+E.nutans,respectively. The change orders of plant diversity indices such as Shannon-Weiner index and Simpson index were bottomlan... |
