摘　　要：在野外调查的基础上,根据TWINSPAN分类结果,采用物种丰富度(R)、Simpson多样性指数(D)、Shannon-Weaver指数(H’)、均匀度指数(E1)等对山西省36个自然保护区湿地的植物物种多样性进行了分析,结果表明:18个群丛的R平均值为1-4.119、H′平均值为0-1.165,二者曲线走势相一致;草本植物群落的H′较小,表明山西省自然保护区湿地植物群落多样性水平偏低;E1平均值为0.17-0.957,其中较大及较小的两个极端均为水生植物群落,而其余湿生及湿中生群丛较居中。在36个自然保护区中,涑水河源头自然保护区R最高,平均值为6;而绵山自然保护区的R最低,平均值为1.5;H′平均值为0.335-1.617。整体而言,山西省南部的自然保护区湿地物种多样性指数普遍高于中、北部地区;E1平均值为0.501-0.984;物种丰富度和均匀度指数与多样性指数呈正相关。The species diversity of wetland plants communities from 36 natural reserves of Shanxi was stud- ied by the diversity indices including species richness index（R）, Simpson index （D）, Shannon-Weaver diversity（H＇） and evenness index（E1） on the basis of field investigation. The results indicated that the 315 samples were divided into 18 associations by TWINSPAN. The average R was between 1--4. 119,the aver- age H＇ was between 0--1. 165 ,the trends of both two indices were similarity. The average H＇ of the herbaceous plant community was small,and this suggested that the diversity level of wetland plant communities in the natural reserves of Shanxi was lower. The average E~ was between 0. 17--0. 957. The two extreme values,the largest and smallest,were both from aquatic plant community,while the average E~ of the other community of hygrophytes and hygro-mesophytes was in the middle. Among the 36 natural reserves, the average R of Sushui River Source Nature Reserve was the highest,while in that of Mian Mountain Nature Reserve was the lowest（R=1. 5）. The average H＇ was between 0. 335--1. 617. In general,the diversity index of the wetland plant communities of the natural reserves in south Shanxi was higher than that in the central and north Shanxi. E1 was between 0. 501--0. 984. There was a positive correlation between the species richness index,evenness index and diversity index.
