摘要
为了解济南市湖库水生生物资源状况,有效保护城市水生态环境,于2021 年秋季对雪野湖开展了浮游生物调查.结果显示,共采集到浮游植物6门40种,其中绿藻门种类数最多,占浮游植物总种类数的 35.00%,浮游植物密度和生物量平均值分别为 10.06×106 cell/L、12.88 mg/L,优势种有5种.采集到浮游动物4类13种,其中轮虫种类数最多,占浮游动物总种类数的38.46%,浮游动物密度和生物量平均值分别为1.93 个/L、0.013 mg/L,优势种有5种.浮游植物和浮游动物Shannon-Wiener多样性指数平均值分别为 1.554、1.556,Pielou均匀度指数平均值分别为0.467、0.966,Margalef丰富度指数平均值分别为1.059、2.873.生物多样性指数水质评价表明,湖区水质整体处于中污染状态,污染程度存在区域差异.
Abstract
In order to understand the status of aquatic resources in the lake and reservoir,and effectively protect the urban water ecological en-vironment,the plankton in Xueye Lake was investigated in the autumn of 2021.The results showed that there were a total of 40 species of phyto-plankton belonging to 6 phyla,among which chlorophyta accounted for 35.00%of the total phytoplankton species,and the average density and average biomass of phytoplankton were 10.06×106 cells/L and 12.88 mg/L,respectively.There were 5 dominant species in phytoplankton.A to-tal of 13 zooplankton species belonging to 4 groups were identified,in which the number of rotifera species was the most,accounting for 38.46%of the total zooplankton species,and the average density and average biomass of zooplankton were 1.93 ind./L and 0.013 mg/L,respectively.There were 5 dominant species in zooplankton.The average Shannon-Wiener diversity index of phytoplankton and zooplankton were 1.554 and 1.556,the average Pielou evenness index of phytoplankton and zooplankton were 0.467 and 0.966,the average Margalef richness index of phy-toplankton and zooplankton were 1.059 and 2.873,respectively.The water quality evaluation of the diversity index showed that the water quality of the Xueye Lake was in the state of medium pollution,and the pollution degree was different in every research area.
