摘　　要：2019年4月至11月在北戴河国家湿地公园进行后生浮游动物和水环境调查,以探究滨海淡水湿地后生浮游动物功能群的季节分布特征及影响因子.采用相似性分析(analysis of similarities,ANOSIM)、非度量多维尺度分析(non-metric multidimensional scaling,NMDS)、Mantel检验、冗余分析(redundancy analysis,RDA)及偏最小二乘路径模型(partial least squares-path modeling,Pls-pm)对后生浮游动物功能群和影响因子进行研究,调查期间共采集并鉴定后生浮游动物95种,共划分为8个功能群.结果显示,研究地后生浮游动物功能群组成春季与夏、秋、冬3季差异显著;小型个体组成的功能群在全年密度和生物量中均占优势;非营养盐类环境因子为后生浮游动物功能群季节演替主要驱动因子;营养盐类环境因子对后生浮游动物功能群季节演替影响较小.The investigation of metazoan zooplankton and water environment were operated from April 2019 to November 2019 in Beidaihe national wetland park,in order to analyze the temporal distribution of metazoan zooplankton functional groups and environmental driving factors.The results showed that a total of 95 species of metazoan zooplankton were identified.According to the size and feeding habits,8 functional groups of metazoan zooplankton were identified.The functional groups are consisted with that small size metazoan zooplankton were dominant in the whole year in density and biomass.There were significant differences in the functional groups of metazoan zooplankton between spring and the other three seasons by analysis of similarities(ANOSIM)and non-metric multidimensional scaling(NMDS)in coastal freshwater wetland.The results showed that the driving factors of distribution of metazoan zooplankton functional groups had seasonal differences by the Mantel test,redundancy analysis(RDA)and partial least squares-path modeling(Pls-pm)in coastal freshwater wetland.The physical-chemical factors were the main driving factors for the seasonal succession of metazoan zooplankton functional groups.Nutrients had little effect on the seasonal succession of metazoan zooplankton functional groups.
