摘要:

为研究人工城市湿地浮游植物的季节性变化及水质因子对浮游植物群落结构变化的影响，于2020年4月至2021年3月，对济西国家湿地逐月进行浮游植物和水质调查，通过典范对应分析（CCA）研究浮游植物群落结构变化与水质因子的响应关系，并分别用浮游植物密度、生物多样性指数对水体进行水华程度及水质评价。结果表明，共发现浮游植物8门166种（属），绿藻门和蓝藻门在物种组成和密度组成占优势地位，浮游植物物种数和密度在夏、秋两季较高，冬季明显变小，生态保育区物种数和密度最高。香农-维纳（Shannon-Weiner）多样性指数（H′）和皮耶罗（Pielou）均匀度指数（J）均在夏季达到最大值，冬季为最小值，科普宣教区最高，生态恢复区最低。总磷、水温、氨氮和电导率对济西国家湿地浮游植物群落结构影响显著。研究表明，济西国家湿地水体属于轻度水华，轻度污染状态，浮游植物群落结构时空差异明显。

Abstract:

In order to study the seasonal changes of phytoplankton in artificial urban wetlands and the influence of water quality factors on the structural changes of phytoplankton communities， a monthly phytoplankton and water quality survey was conducted on Jixi National Wetland from April 2020 to March 2021， and the structural change of phyplankton community was studied through canonical correspondence analysis（CCA）. The response relationship between chemical and water quality factors， and the water intensity and water quality of the water body are evaluated by phytoplankton density and biodiversity index respectively. The results show that a total of 166 species（genera） of 8 phytoplankton have been found. Green algae and cyanobacteria have a dominant position in species composition and density composition. The number and density of phytoplankton species are higher in summer and autumn， significantly smaller in winter， and the number and density of ecological conservation area are the highest. The Shannon-Weaner Diversity Index（H′） and the Pielou Uniformity Index（J′） both reach the maximum in summer and the minimum in winter， with the highest in Science popularization and education area and the lowest in ecological restoration area. The results of CCA show that total phosphorus， water temperature， ammonia nitrogen， and conductivity have a significant impact on the structure of phytoplankton communities in Jixi National Wetland. Research shows significant spatiotemporal difference in the structure of phytoplankton communities in Jixi National Wetland. The water quality of Jixi National Wetland is in the state of mild algal bloom and is slightly polluted.
