哈尔滨松北国家湿地公园春季浮游动物功能群研究
Study on Zooplankton Functional Groups in Harbin Songbei National Wetland Park in Spring

为了解松北国家湿地公园春季的水体浮游动物群落结构特征及其与水环境因子之间的关系，2021年5月在松北国家湿地公园设置了8个采样点并进行浮游动物的采集以及水体理化因子的测定。结果表明，因未发现小型浮游动物捕食者SCC、中型浮游动物捕食者MCC、大型浮游动物捕食者LCF，因此共划分为七个功能群，其中以RF功能群占显著优势。除此之外，通过Pearson相关分析和RDA多元统计分析，功能群PF与LCC之间存在强负相关，理化因子TN和TP与各浮游动物功能群之间存在明显的正相关性，pH具有一定的负相关性，水温则不具有明显相关性。
In order to understand the characteristics of the zooplankton community structure in the water column during spring in the Songbei National Wetland and the relationship between it and water environmental factors, as well as to evaluate the water environmental health system through data such as phytoplankton diversity, eight sampling sites were set in the Songbei National Wetland in May 2021 and collection of plankton and determination of water physicochemical factors were performed. A total of seven functional groups were classified, with the RF functional group dominating, since SCC of small zooplankton predators, MCC of medium zooplankton predators and LCF of large zooplankton predators were not found. Besides that, there were strong negative correlations between functional groups PF and LCC, clear positive correlations between physicochemical factors TN and TP and each zooplankton functional group by Pearson correlation analysis and RDA multivariate statistical analysis, some negative correlations between pH and water temperature.
