西泉眼水库浮游动物群落结构与分析 鞠永富于洪贤*** 于 婷2 柴方营2 （东北林业大学野生动物资源学院，黑龙江哈尔滨150040黑龙江哈尔滨150040 摘 要 2010年夏季西泉眼水库浮游动物群落结构特征，运用指标评价法指示生物法、多样性分析法、QB/T指数分析法、EO指数分析法、肥度指数法(E)和因子价法评价了其水质应用典范对应分析法浮游动物环境因子的相关性.结果：共检测出浮游动物56种原生动物14种，轮虫29种，枝角类4种，桡足类9种污染指示种53种，其中α-中污指示种16种，占30.2%；丰度为29.25ind./L生物量0.1mg/L；优势种为褐砂壳虫Difflugia avellana、长三肢轮虫Filinia longiseta、针簇多枝轮虫Polyarthra minor、微刺小剑水蚤Microcyclops inchoatus和无节幼体；Shanno-Wiener指数为2.63，Margalef丰富度指数为1.89，QB/T指数为2，EO指数为3.2CCA分析表明NO3-、NO3-N、CL、COND、Depth、NH4+、TP和chla是影响浮游动物分布的主要环境因子.综合西泉眼水库水质处中污染状态水体处中营养水平作为饮用水源地其水质还需进一步加强管理与调控. 西泉眼水库；浮游动物；； Analysis on the composition and community structure of phytoplankton during winter in Ju Yongfu1,2, Yu Hongxian1*, Yu Ting2, Chai Fangying2 (College of Wildlife Resource，Northeast Forestry University，Harbin 150040，China) Abstract The changes of composition and diversity of Zooplankton direct affect the water ecosystem’s structure and function, which is important to maintain the balance of aquatic ecosystem . In this paper, the author collected water samples from 10 sites of Hailang River in February 2010,and the Multidimensional scaling (MDS) index was used to study the characteristics of community composition of zooplankton. The results showed that:(a) total of 4 phla 16 species, of which protozoa is the most, 7 classes and 8 species, accounting for 50%; Rotifera 6 classes and 6 species, accounting for 37.5%; Copepod 2 classes and 2 species, accounting for 12.5%; Cladocera is not found;(b) the average abundance and biomass of zooplankton were 4.9 × 104 ind. / L and 0.1293 mg / L; (c) the 10 sites were divided into two groups y using the MDS analysis,the inergroup dissimilarity is small but between the groups is larger. Keywords　Hailang River; Zooplankton; Non-metric Multidimensional scaling 西泉眼水库位于阿什河干流上游，是目前黑龙江省规模最大的综合型水库之一，是哈尔滨市的备用水源地.近几年，西泉眼水库水体污染情况的报道较多[1-4]，水库上游流域点污染源主要有制药厂、疗养院、钢铁厂、矿厂、养殖厂等；面源污染主要有耕地和森林喷洒农药、林药，降雨径流及农田灌溉退水，上游村屯、城镇的地表径流等；旅游污染源主要有金泉国家森林公园、帽儿山森林公园、横头山森林公园、松峰山旅游区等. 生物与环境的统一是生物与环境相互作用的结果
