摘　　要：于2023年春季,对厦门杏林湾水库开展了浮游生物群落生态特征的调查,并从水质变化参数与生物多样性健康评价。结果表明,浮游植物4门45种,其中绿藻门种类数最多,占总种类数的58.00%,主要优势种有长刺根管藻、梅尼小环藻、四尾栅藻等;浮游植物的平均密度和平均生物量分别为9.22 × 104 cells/L和41.5 μg/L。浮游动物共鉴定出4类28种,其中轮虫数量最多,约占50.00%,主要优势种有无节幼体、圆型臂尾轮虫、萼花臂尾轮虫等;浮游动物的平均密度和平均生物量分别为55.51 ind/L和0.542 mg/L。综合浮游植物和浮游动物的调查结果,根据生物多样性水质评价标准可知杏林湾水库的水质整体较差,浮游生物丰富度较低。The plankton in Xinglinwan Reservoir was investigated and health evaluation was studied from water quality change parameters and biodiversity in the spring of 2022. The results showed that there were a total of 45 species of phytoplankton belonging to 4 phyla, among which Chlorophyta accounted for 58.00% of the total phytoplankton species, the main dominant species were Rhizosolenia longiseta, Cyclotella meneghiniana, Scenedesmus quqdricauda, etc. The average density and average biomass of phytoplankton were 9.22104 cells/L and 41.5 μg/L, respectively. There were 28 species of zooplankton belonging to 4 groups, the number of rotifera was the most, accounting for50.00% of the total zooplankton species, the main dominant species were Nauplius, Brachionus rotundiformis, Brachionus calyciflorus, etc. The average density and average biomass of zooplankton were 55.51 ind/L and 0.542 mg/L, respectively. Based on the survey results of phytoplankton and zooplankton, the water quality evaluation standard of biodiversity shows that the water quality of Xinglinwan Reservoir is poor and the plankton richness is low.
