河南黄河中游湿地维管植物与哺乳动物物种组成和分布特征

河南黄河湿地位于黄河中下游，由西向东随地势变化，动植物物种组成及多样性变化复杂。于2011年至2015年对三门峡市、洛阳市以及焦作市的黄河湿地保护区维管植物和哺乳动物进行了全面调查，比较分析了三个区域间动植物多样性的差异，采用非趋势对应分析和聚类分析对物种组成数据进行排序和分类，结果显示：（1）三门峡、洛阳和焦作黄河湿地维管植物分别有130科、493属、1128种及变种，128科、470属、1049种及变种，90科、290属、542种及变种；三门峡黄河湿地哺乳动物有6目、15科、48种，洛阳黄河湿地哺乳动物有7目、18科、61种，焦作黄河湿地哺乳动物有6目、11科、34种；（2）从三门峡黄河湿地经洛阳黄河湿地再到焦作黄河湿地，维管植物多样性降低；（3）三门峡黄河湿地维管植物多样性和哺乳动物多样性与洛阳黄河湿地差异不显著，与焦作黄河湿地差异显著。研究结果丰富了河南黄河湿地保护区植物和动物多样性研究资料，同时也为保护区的保护管理和科研监测提供参考。

Vascular plant and mammal species composition and distribution of wetland in the middle reaches of the Yellow River in He'nan Province

The Yellow River Wetland in He''nan Provence is located in the middle and lower reaches of the Yellow River and plays an important role in watershed ecological security. From west to east with the change of topography, plant and animal species composition and diversity changes complex. From 2011 to 2015, a comprehensive survey of vascular plants and mammals in the Yellow River Wetland Reserve in Sanmenxia, Luoyang and Jiaozuo was conducted to compare and analyze the differences of plant and animal diversity among the three regions. Detrended Correspondence Analysis (DCA) analysis and cluster analysis were used to sort and classify the species composition data. Results showed that:(1)there were 130 families, 493 genera and 1128 species of plants and 6 orders, 15 families and 48 species of mammals in Sanmenxia Yellow River Wetland; there were 128 families, 470 genera, 1049 species of vascular plants and 7 orders, 18 families and 61 species of mammals in Luoyang Yellow River wetland; and there were 90 families, 290 genera, 542 species of plants and 6 orders, 11 families and 34 species of mammals in Jiaozuo Yellow River wetland. (2) The diversity of vascular plants decreased from Sanmenxia Yellow River Wetland to Luoyang Yellow River Wetland to Jiaozuo Yellow River Wetland. (3) The vascular plant diversity and mammals diversity of the Yellow River Wetland in Sanmenxia were not significantly different from Luoyang Yellow River Wetland, but were significantly different from Jiaozuo Yellow River Wetland. The results enrich the research data of plant and animal diversity in the Yellow River Wetland Reserve in He''nan Province, and provide a basis for the conservation management and scientific research monitoring of the reserve.
