中文摘要：

在浮游动物丰富，生物资源，种类差异和社区结构的季节的变化在 Sanmen 海湾被调查，中国。样品从 15 个车站是镇定的，在季节的基础上，在 4 月(春天) ， 7 月(夏天) 和 2005 年 10 月(秋天) 和 2006 年 1 月(冬季) 分别地。结果显示出那个浮游动物种类数字，广泛地改变并且在 Sanmen 海湾有不同空间异质的丰富和生物资源。属于 56 个类和 17 组远洋的幼虫的浮游动物的 72 种类的一个总数被识别。浮游动物种类丰富是强烈与咸度有关。基于层次簇分析，在这个学习区域的浮游动物被分类进三个组：沿海、浅海、远洋的组，它分别地对应于 Sanmen 海湾的上面、中间、更低的部分。沿海的低盐的种类在学习区域是主导的。浮游动物丰富和生物资源在夏天到达了一座山峰，在冬季在春天和秋天中等、最低。浮游动物丰富减少了从对在 4 月的海湾的更低的部分上面，当最高的生物资源发生在海湾的中间的部分时。在 7 月为生物资源和丰富有一样的空间分发模式，与在海湾的中间的最大值。然而，浮游动物丰富在在 10 月的海湾的中间是最高的，当最大的生物资源发生了在附近时海湾更低。浮游动物丰富和生物资源均匀地在 1 月在 Sanmen 海湾被散布。在有环境因素的浮游动物和他们的关系的空间、时间的变化也被分析。BIOENV 结果显示叶绿素的联合一(Chl -- 一) ，咸度，溶解的无机的氮(吵闹) ，溶解的氧() 并且硅酸盐(SiO3 ) 为在在 Sanmen 海湾的浮游动物社区结构的变化负责。环境变化在 Sanmen 海湾在浮游动物社区结构在变化起了一个重要作用。

英文摘要：

Seasonal variations in zooplankton abundance, biomass, species diversity and community structure were investigated in the Sanmen Bay, China. Samples were collected from 15 stations, on the seasonal basis, in April （spring）, July （summer） and October 2005 （autumn） and January 2006 （winter）, respectively. The results show that zooplankton species number, abundance and biomass varied widely and had distinct spatial heterogeneity in the Sanmen Bay. A total of 72 species of zooplankton belonging to 56 genera and 17 groups of pelagic larvae were identified. The zooplankton species richness was strongly related to salinity. Based on hierarchical cluster analysis, zooplankton in this study area were classified into three groups： coastal, neritic and pelagic groups, which corresponded to the upper, middle and lower portion of the Sanmen Bay, respectively. The coastal low-saline species were dominant in the study area. The zooplankton abundance and biomass reached a peak in summer, moderate in spring and autumn, and the lowest in winter. Zooplankton abundance decreased from the upper to lower portion of the bay in April, when the highest biomass occurred in the middle portion of the bay. There were the same spatial distribution patterns for the biomass and abundance in July, with the maximum in the middle of the bay. However, zooplankton abundance was the highest in the middle of tile bay in October, when maximum biomass occurred near the lower of the bay. Zooplankton abundance and biomass were evenly distributed in the Sanmen Bay in January. Spatial and temporal variations in zooplankton and their relationship with environmental factors were also analyzed. The BIOENV results indicate that the combination of chlorophyll a （Chl-a）, salinity, dissolved inorganic nitrogen （DIN）, dissolved oxygen （DO） and silicate （SiO3） was responsible for the variations in zooplankton community structure in the Sanmen Bay. The environmental changes played an important role in changes in the zooplankton commu
