%X 为了解西泉眼水库春季的水体浮游植物群落结构特征及其与水环境因子之间的关系，于2021年5月在水库内采用内陆水域大面积定点调查方法共设置了18个采样点，并进行浮游动物的采集和水体理化因子的测定。本文中运用了优势种、生物多样性指数、RDA (冗余分析)等方法对浮游动物及水环境因子进行分析。结果共鉴定出浮游植物7门30种，丰度波动在48 × 10<sup>4</sup> ind./L~236.4 × 10<sup>4</sup> ind./L之间；生物量在0.91 mg/L~3.324 mg/L之间。评价结果显示春季西泉眼水库呈轻–中污染。冗余分析结果表明水温、TP、COD和PH是影响浮游植物群落变化的主要水环境因子。<br />
In order to understand the characteristics of phytoplankton community structure in xiquanyan Reservoir in spring and its relationship with water environmental factors, a total of 18 sampling sites were set up in the reservoir in May 2021 by a large-scale fixed-point survey in inland waters. Zooplankton was collected and water physical and chemical factors were measured. In this paper, dominant species, biodiversity index, RDA (redundancy analysis) and other methods were used to analyze zooplankton and water environmental factors. A total of 30 species of phytoplankton from 7 phyla were identified, and their abundance ranged from 48 × 10<sup>4</sup> ind./L to 236.4 × 10<sup>4</sup> ind./L. The biomass ranged from 0.91 mg/L to 3.324 mg/L. The evaluation results show that the xiquanyan reservoir is light-medium polluted in spring. The results of redundancy analysis showed that water temperature, TP, COD and PH were the main environmental factors affecting phytoplankton community change.
