摘要: 为研究唐山湾海域浮游动物群落结构与环境因子的关系,于2015年4月(春季)、7月(夏季)、10月(秋季)和12月(冬季)对唐山湾海域浮游动物群落结构、环境因子进行航次调查,并利用多元统计分析和相关分析法分析了浮游动物群落结构的时空变化及其主要环境驱动因子.结果表明: 影响唐山湾海域浮游动物丰度的主要环境因素为无机氮(DIN)、悬浮物(SS)、水温(T)和叶绿素a(Chl a);唐山湾海域浮游动物群落结构的空间差异主要受溶解氧(DO)、T和Chla的驱动;在唐山湾不同海域中,影响浮游动物群落结构的因素存在差异,其中乐亭海域和三岛海域浮游动物群落结构的主要影响因素为物理因素,曹妃甸海域则主要受化学因素的影响.这表明在唐山湾人类活动影响强度大的海域,浮游动物群落结构更多地受化学因素影响(DIN、活性磷酸盐),而人类活动影响小的海域则更多地受物理因素的影响(T、SS).

Abstract: In order to study the relationship between zooplankton community structure and environmental factors in Tangshan Bay, the zooplankton community structure and environmental factors were investigated in 2015 April (spring), July (summer), October (autumn) and December (winter). The temporal and spatial variation of zooplankton community structure and its main environmental driving factors were analyzed by means of multivariate analysis and correlation analysis. The results showed that the main environmental factors affecting the abundance of zooplankton in Tangshan Bay were DIN, SS, temperature and Chla. Multivariate analysis indicated that DO, temperature and Chl a were the principal factors driving spatial differentiation of zooplankton community structure in Tangshan Bay. In different waters of Tangshan Bay, the environmental factors affecting zooplankton community structure were different. The main influencing factors were physical variables for Laoting and Sandao sea areas, while chemical variables for Caofeidian sea area, respectively. The results revealed the zooplankton community structure was more influenced by chemical variables (DIN, SRP) in sea areas heavily affected by human activity, while it was more influenced by phy-sical variables (T, SS) in sea areas less affected by human activity.
