| 摘 要： | 采用样带法研究了玛曲高寒湿地的植物群落特征及生物多样性，结果表明，出现在样地内的主要植物有24种，隶属于14科22属，优势种为高山嵩草（Kobresia pygmaea），次优势种为珠牙蓼（Polygonum viviparnm）、鹅绒委陵菜（Potentilla anserina）、矮藨草（Scirpus triquete）等。群落生活型组成中地面芽植物占优势，占总数的83%；群落垂直结构明显，大体分3层；通过对4条样带上生物多样性指数进行单因素方差分析，其中丰富度指数（R1、R2）、多样性指数（Simpson多样性指数D、Shannon Wiener多样性指数H）、均匀度指数(E1、E2)分别为17.75、1.50、1.34、0.39、0.23和0.09。

| Abstract: | The sample belts were used to survey the plant communities and their diversity of Maqu Alpine Wetland.This study showed that 24 plant species belonging to 22 genera of 14 families were identified in this field survey,in which the Kobresia pygmaea was dominant,and the Polygonum viviparnm,Potentilla anserine,and Scirpus triquete were subdominant.In the life form components,the hemicryptophyte was dominant and accounted for 83% of the total.The vertical structure of plant communities were divided into three layers.The richness index(R1,R2),diversity index(Simpson diversity index D,Shannon-Wiener diversity index H) and evenness index(E1,E2) was 17.75,1.50,1.34,0.39,0.23,and 0.09,respectively. |
