【摘要】：为了解海州湾海洋牧场浮游动物群落结构季节性变化特征及其与环境因子的关系,分别于2015年春(5月)、夏(8月)、秋(10月)进行了3个航次的调查,共鉴定出浮游动物29种,其中,节肢动物门最多,有20种,毛颚动物门4种,腔肠动物门3种;桡足纲及甲壳纲浮游动物为当地主要种类。海州湾海洋牧场秋季浮游动物种类数达16种,大于夏季(10种)和春季(8种)。人工鱼礁区各个季节的浮游动物群落丰度与对照区无显著差异(P0.05),春、夏两季的浮游动物群落种类数无显著区域性差异(P0.05),而秋季对照区浮游动物种类数显著高于人工鱼礁区(P0.05)。海州湾海洋牧场浮游动物夏季种类数显著高于春季(P0.05);秋季浮游动物丰度显著低于春、夏两季(P0.05)。人工鱼礁区和对照区的Shannon-wiener多样性指数均在夏季达到最大值,分别为1.571和2.107,春季最小,为0.380和0.554;而均匀度则在秋季达到最大值,分别为0.214和0.224,且春季浮游动物群落结构与夏、秋两季相似度较低,夏、秋两季群落结构更复杂。典范对应分析结果表明,影响浮游动物群落丰度及分布的主要因素为海表温度(SST)、生物需氧量(BOD_5)、叶绿素(Chl-a)、溶解氧浓度(DO)和部分营养盐(SiO_3~(2-)-Si、NO_3~--N和PO_4~(3-)-P),且影响因素存在季节性差异。浮游植物群落丰度也是影响浮游动物群落丰度及分布的重要因素之一。
[Abstract]:In order to understand the seasonal variation characteristics of zooplankton community structure and its relationship with environmental factors in Haizhou Bay Marine pasture, 3 voyages were investigated in spring 2015 (May), summer (August) and autumn (October), and 29 species of zooplankton were identified. Among them, there were 20 species of arthropods, 4 species of hair jawed animals, 3 species of coelintestinal animals; Copepoda. There are 16 species of zooplankton in Haizhou Bay Marine pasture in autumn, which are more than summer (10) and spring (8 species). There is no significant difference between the abundance of zooplankton community in each season of artificial reef and the control area (P0.05), and there is no significant regional difference in the number of zooplankton community in spring and summer (P0.0). 5), the number of zooplankton in the autumn control area was significantly higher than that in the artificial reef area (P0.05). The species of zooplankton in the Haizhou Bay Marine pasture were significantly higher than that in spring (P0.05), and the abundance of zooplankton in autumn was significantly lower than that in spring, and in summer and two seasons (P0.05). The Shannon-wiener diversity index of artificial reefs and control areas reached the maximum in summer. Not 1.571 and 2.107, the smallest in spring, 0.380 and 0.554, and the evenness reached the maximum in autumn, 0.214 and 0.224, and the structure of the zooplankton community in spring was lower than the summer, autumn and two quarter, and the summer and autumn two quarter were more complex. The results of canonical correspondence analysis showed that the main factors affecting the abundance and distribution of the zooplankton community For sea surface temperature (SST), bio oxygen demand (BOD_5), chlorophyll (Chl-a), dissolved oxygen concentration (DO) and some nutrient salts (SiO_3~ (2-) -Si, NO_3~--N and PO_4~ (3-) -P), and there are seasonal differences in influence factors. Phytoplankton abundance is also one of the important factors affecting the abundance and distribution of zooplankton community.
