| 摘 要： | 为了更好地了解合肥市饮用水源地水生态环境状况，于2020年夏季、秋季、冬季及2021年春季对大房郢水库的水质、浮游植物和浮游动物进行监测，对比浮游生物群落现存量与历史变化，并使用冗余分析（RDA）以及蒙特卡洛置换检验探究环境因子对浮游生物群落的影响。结果表明，研究区域浮游植物以蓝藻门为主要优势种属，密度及生物量较2005年分别增加37.7%和7.0%，浮游动物以桡足类为主要优势种，密度较2005年大幅度下降了77.5%，生物量多样性增加了47.8%，影响浮游生物群落结构的主要环境因子为NH3-N、T（温度）、pH和TN。此外，研究也揭示了季节变化对水库浮游生物的物种组成影响小，但对浮游生物的丰度及多样性影响显著。

| Abstract: | In order to better understand the ecological environment of drinking water sources in Hefei City, the water quality, phytoplankton and zooplankton of Dafangying Reservoir were monitored in the summer, autumn, winter of 2020, and spring of 2021. The existing and historical changes of plankton communities were compared, and the impact of environmental factors on plankton communities was explored using redundancy analysis (RDA) and Monte Carlo displacement test. The results showed that the dominant species of phytoplankton in the study area were cyanobacteria, with a density and biomass increase of 37.7% and 7.0%, respectively as compared to 2005. The dominant species of zooplankton were copepods, with a density decrease of 77.5% and a biomass diversity increase of 47.8%. The main environmental factors affecting the structure of phytoplankton communities were NH3-N, T (temperature), pH, and TN. In addition, the study also revealed that seasonal changes had a small impact on the species composition of plankton in reservoirs, but had a significant impact on the abundance and diversity of plankton. |
