摘要:
 以渭河中段河漫滩草本植物群落为研究对象，采用群落生态学的调查方法，探讨多样性变化格局，为渭河景观恢复重建和生物多样性保护提供科学依据。结果表明：1）研究区共有草本植物168种，隶属于119属43科，优势科有菊科（Compositae）、禾本科（Gramineae）、莎草科（Cyperaceae）、蓼科（Polygonaceae）。2）各样地优势种和伴生种有差异，多为禾本科和菊科植物。3）Shannon-Wiener多样性指数（H）在1.62～2.32之间，Simpson多样性指数（DS）在0.85～0.96之间。Pielou均匀度指数（JP）在0.61～0.85之间。α多样性变化格局与丰富度指数变化格局比较一致。4）相异性系数和Cody指数变化格局比较一致。渭河中段河漫滩草本植物多样性指数偏低，受人为干扰因素影响较大。
Abstract:
 In order to provide scientific data for vegetation landscape restoration and biodiversity conservation in the middle reaches of Wei River, this paper focused on analyzing the biodiversity of herbaceous seed plants in wetlands by using the community ecology research method. The results showed: 1) a total of 168 species, belonging to 43 families and 119 genera, were found in the studied area. And among them, the Compositae, Gramineae, Cyperaceae and Polygonaceae were dominant families. 2) The dominant species and associated species were different among the sampling plots, mostly Gramineae and Compositae. 3) The values of Simpson index (DS) of the herbs were between 0.85 to 0. 96. Those of Shannon Weiner index (H) were 1.62 to 2.32. And those of evenness index (JP) were 0.16 to 0.85. The data indicated that the diversity indices were low. Alpha diversity had a similar trend compared with species. 4) The β diversity showed a similar pattern with Cody index, which were mainly decided by the habitat condition variation and human factors.
