为了解贵州省雅水镇水头水库浮游生物群落结构的时空演替特征及水质状况，于2018年12月(冬)、2019年3月(春)对水头水库开展水质与浮游生物综合性调查。调查期间，共检出浮游藻类7门57属69种(包括变种),其中冬季检测到浮游藻类7门46属49种，春季检测到浮游藻类5门29属34种，调查期间绿藻门(Chlorophyta)和硅藻门(Bacillariophyta)为优势类群。冬季浮游藻类平均密度与平均生物量分别为5.98×104 ind/L和83.32×10-3 mg/L;春季浮游藻类平均密度与平均生物量分别为14.39×104 ind/L和64.70×10-3 mg/L。共检出浮游动物3门26种，其中轮虫(rotifer)8种、枝角类(cladoceran)11种以及桡足类(copepod)7种。冬季浮游动物平均密度与平均生物量分别为14.40×102 ind/L和62.20 mg/L;春季浮游动物平均密度与平均生物量分别为17.55×10~2ind/L和55.55 mg/L。浮游生物多样性结果显示水头水库在调查期间属于中度污染类型，且部分采样点水质有劣化趋势，浮游生物水质分析结果与水体理化特征评价结果相对一致。本研究通过揭示雅水镇水头水库的浮游生物群落结构，并评价其水质状况，从而为该地区的水域生态环境现状和水源地保护措施提供基础资料。
Abstract：In order to understand the temporal and spatial succession characteristics of the plankton community structure and water quality in Shuitou reservoir, Yashui town, Guizhou province, a comprehensive survey of water quality and plankton in Shuitou reservoir werelaunched in December 2018 and March 2019. During the study period, a total of 69 species of phytoplankton in 57 genera(including variants) were detected in 7 phyla. Among them, 49 species of phytoplankton in 7 phyla and 46 genera were detected in winter, and 34 species in 29 genera and 5 phyla were found in spring. Chlorophyta and Bacillariophyta were dominant groups. The average density and average biomass of phytoplankton in winter were 5.98×104 ind/L and 83.32×10-3 mg/L, respectively; the average density and average biomass of phytoplankton in spring are 14.39×104 ind/L and 64.70×10-3 mg/L, respectively. A total of 26 species of zooplankton were identified in 3 phyla, including 8 species of rotifer, 11 species of cladoceran, and 7 species of copepod. The average density and average biomass of zooplankton in winter were 14.40×102 ind/L and 62.20 mg/L; the average density and average biomass of zooplankton in spring were 17.55×102 ind/L and 55.55 mg/L, respectively. Results of plankton biodiversity showed that Shuitou reservoir belonged to moderate pollution during the survey period, but the water quality of some sampling points had a tendency to deteriorate. The evaluation results corresponded to the analysis results of water quality and hydration characteristics. This study reveals the plankton community structure of Shuitou reservoir in Yashui town, and evaluates its water quality, so as to provide basic information for the current situation of the water ecological environment and water source protection measures in the area.
