| 摘 要： | 为了解黄河流域湿地水生生物群落结构特征及生态环境现状，于2020年4月至2021年3月调查了济南段城市湿地—济西湿地公园浮游动物群落结构，监测分析了水环境因子变化特征及水环境质量状况。结果表明：济西湿地公园全年共采集鉴定出浮游动物4大类66种，平均密度为181.8 ind./L，平均生物量为0.210mg/L；浮游动物划分为7个功能群，春季、夏季、冬季均以功能群RF和PF为主，最高占比分别为62.86%、20.75%，秋季以功能群RF和SCF为主，占比分别为58.54%、12.20%；浮游动物Shannon-Wiener指数(H'')、Pielou均匀度指数(J)和Margalef丰富度指数（D）平均值分别为2.50、0.71、2.31；综合营养状态指数水质评价结果显示济西湿地公园水质整体处于中营养化水平；Pearson相关性分析表明WT、COND、DO、NO2--N、SS、TP、PO43-和Chl-a是显著影响浮游动物功能群的主要环境因子。该研究对济西湿地的生态效应评估和水资源保护具有一定的指导意义。

| Abstract: | Jixi wetland park is a typical urban wetland located in the urban area of west Jinan City, providing drinking water for Jinan City, flood control and ecological conservation. In this study, we explored the characteristics of zooplankton functional groups as well as their relationship with the physiochemical factors in Jixi wetland park. The objectives were to understand the structure and function of the wetland ecosystem and provide theoretical support for evaluating and managing water quality in Jixi wetland. From April 2020 to March 2021, zooplankton sampling and environmental monitoring was conducted monthly at six representative sampling sites (JX1-JX6) in Jixi wetland. A total of 66 zooplankton species were collected during the investigation and divided into 7 functional groups (PF: protozoan filter feeders, RF: rotifer filter feeders, RC, rotifer carnivores; SCF: small copepods and cladocera filter feeders, MCF: middle copepods and cladocera filter feeders, MCC: middle copepods and cladocera carnivores, LCF: large copepods and cladocera carnivores). Zooplankton density and biomass were in the ranges of 16.0 -824.0 ind/L and 0.004 -1.667 mg/L, with average annual values of 181.8 ind/L and 0.210mg/L. Groups RF (rotifer filter feeders) and PF (protozoan filter feeders) were dominant in spring , summer and winter, and the highest proportion of group RF (62.86%) was in winter, and the highest proportion of group PF (20.75%) was in spring, and group RF (rotifers filter feeders) (58.54%) and SCF (small copepods and cladocera filter feeders) (12.20%) were dominant in autumn. The mean value of the Shannon-Wiener diversity index, Pielou evenness index and Margalef richness index of the zooplankton community were 2.504, 0.708 and 2.307, respectively. The water quality was evaluated using the comprehensive trophic level index and the results show that the water quality of Jixi wetland was mesotrophic. Canonical correspondence analysis shows that WT, COND and PO43- were the environmental factors significantly affecting zooplankton functional groups. This study will help guide ecological effect assessment and water resource protection of Jixi wetland. |
