| Abstract | Based on two surveys conducted in August 2013 and May 2014 in Caofeidian coastal waters, we studied the temporal and spatial variations of species composition, abundance, biomass, dominant species, and the diversity of the zooplankton community; analyzed their relationships with environmental factors; and compared it with an investigation in 2004 to discuss the changes of zooplankton abundance and dominant species and reclamation impacts. A total of 31 species were identified, which were mainly composed of copepod and larvae. Dominant species include Acartia bifilosa, Paracalanus parvus, Oithona similis, and Copepodid larva. Compared to summer, spring exhibited higher values in zooplankton abundance and biomass but lower values in diversity and in the evenness index. Zooplankton spatial distribution of abundance was largely related to seawater temperature and chlorophyll a (Chl-a). Zooplankton abundance showed a roughly decreasing trend from inshore to offshore waters in spring, whereas showing a converse pattern with high values distributed in offshore waters in summer. A comparison with the investigation in 2004 revealed an obvious decline of zooplankton abundance in spring and summer, possibly due to the decrease of dissolved inorganic phosphorus and phytoplankton abundance. The western (eastern) waters showed a decrease (an increase) in zooplankton abundance in spring, which is related to the promoted phytoplankton proliferation induced by nutrient redistribution after reclamation. The study area was mainly impacted by riverine inputs in summer, and the changes in zooplankton abundance showed no obvious spatial variation. |
| Other Abstract | 根据2013年8月(夏季)和2014年5月(春季)在曹妃甸邻近海域的调查资料,研究了浮游动物群落的种类组成、丰度、生物量、优势种和多样性的时空变化特征,分析了其与环境因子的关系,并结合2004年调查资料对比分析了浮游动物丰度和优势种的变化特征及围填海的影响。结果表明,研究海域浮游动物共鉴定得到31种(类),以桡足类和浮游幼体为主,优势种主要包括双刺纺锤水蚤(Acartia bifilosa)、小拟哲水蚤(Paracalanus parvus)、拟长腹剑水蚤(Oithona similis)和桡足类幼体(Copepodid larva)等。春季的浮游动物丰度和生物量均高于夏季,多样性和均匀度指数均低于夏季。浮游动物丰度的空间分布主要受温度、叶绿素a(Chl-a)等环境因子影响,春季基本为近岸高、远岸低的空间分布规律,夏季则相反,基本为近岸低、远岸高的空间分布规律。与2004年相比,本次调查春季和夏季的浮游动物丰度明显下降,可能与浮游植物丰度及DIP浓度降低有关。春季,西侧、东侧海域的浮游动物丰度分别明显降低、升高,与围填海后营养盐重新分布促进了东侧海域浮游植物增殖有关。夏季则主要受河流输入影响,浮游动物丰度的变化不具有空间差异。 |
