中文摘要:
      基于2012年4月杭州湾南岸宁波慈溪附近水域(27°38'-28°02'N、120°50'-121°14'E)浮游生物生态群落分布特征,分析这一分布特征与营养化水域的关系。结果表明,调查期间海域富营养化指标E值大于1,富营养化程度较为严重;水域高浓度悬沙使水体透光率较低,不利于浮游植物生长,悬沙浓度低的水域是浮游植物高密度水域。浮游植物和浮游动物丰度分布趋势基本相同,两者之间显著地呈线性正相关关系。这一特征的形成,主要由调查水域营养盐和悬浮物分布特征决定。春季浮游动物种类数和优势种种数(2种)相对较少,并呈现出单一优势种的优势度和平均丰度高,多样性指数均值低(1.05)的特征。虽然浮游动物群落结构不太稳定,但浮游动物与浮游植物空间分布的一致性很好地反映出浮游动物对浮游植物有效的摄食压力,从而使生态系统在春季富营养化水域保持相对稳定。
英文摘要:
      The characteristics of the spatial distribution of plankton in the Hangzhou Bay estuary (27°38'- 28°02'N, 120°50'-121°14'E) were investigated in April, 2012. The correlation between the distribution of plankton and eutrophication was studied, and the results were presented in the paper. During the investigation, serious eutrophication prevailed with eutrophication index (E) higher than 1; the growth of phytoplankton was limited by light intensity due to high suspended particulate (SP) in the estuary. High abundance of phytoplankton was observed as light condition improved because of decreasing SP concentration. The distribution pattern of zooplankton was in coincidence with that of phytoplankton. The abundance of zooplankton was significantly correlated with that of phytoplankton, suggesting the limitation of eutrophication and SP on production in the Hangzhou Bay. In spring, the species number and the dominant species number (2 species) were relatively small, and also displayed the characters of high dominance and average abundance of single dominant species and average value relatively of diversity index low (1.78). Though the structure of zooplankton was not very stable, the coincidence in the distribution of zooplankton and phytoplankton indicates the grazing pressure of zooplankton on the growth of phytoplankton. We conclude that the ecosystem in the eutrophication areas of Hangzhou Bay was stabilized in spring.
