摘    要:通过对榆林风沙草滩区的主要物种进行考察,根据植被、立地条件及土壤水分等因素,选取5个典型样地,应用物种丰富度指数(R1)、Shannon--Weiner多样性指数(H)、Simpson多样性指数(D)和Pielou均匀度指数(E,)综合分析了主要物种的丰富度、多样性和均匀度,并对其重要值和土壤水分与物种多样性的关系进行了研究。结果表明,榆林风沙草滩区主要物种的多样性排列顺序为:紫穗槐群落〉柠条群落〉踏郎群落〉沙柳群落〉沙蒿群落;均匀度排列顺序为:沙柳群落〉紫穗槐群落〉柠条群落〉踏郎群落〉沙蒿群落;土壤含水量排列顺序为:紫穗槐群落〉沙蒿群落〉沙柳群落〉柠条群落〉踏郎群落。

关 键 词:榆林风沙草滩区  物种多样性  多样性指数  土壤含水量

Abstract:T hrough investigating the main species of different communities in the wind-sandy grass shoal area of Yulin Region, 5 representative areas were selected according to vegetation, site factor, and soil water content.Species richness, species diversity, and the evenness of community were comprehensively calculated by using richness index ( R1) , Shannon - Weiner index ( H ) , Simpson index ( D) , and evenness index ( E 1) .Meanwhile, the relations of the important value of the main species and soil water content to species diversity were studied.The communities in the wind -sandy grass shoal area of Yulin Region, in terms of the species diversity, rank in the descendent order of Amorphaf raticosa community, Caragana intermedia community, H edysarum scop arium community, Salix cheilop hila community, and A rtemisia arenaria community.However, they, in terms of the evenness of community, rank in the descendent order of Salix cheilophila community, A morp ha f raticosa community, Caraganaintermedia community, Hedysarum scop arium community, and A rtemisia arenaria community.They, in terms of soil water content, rank in the descendent order of A morp ha f raticosa community, Artemisia arenaria community, Caragana intermedia community, and H edysarum scoparium community.
Keywords:Yulin wind-sand grass shoal area  species diversity  species diversity index  soil water content
