中文摘要:
      洋山港是中国首个离岸式深水港口,小洋山位于洋山港海域北侧。2012年1月-12月对小洋山近岸水域浮游植物进行了采样调查,共鉴定出浮游植物183种,隶属7门77属。其中硅藻门为主要类群,共51属143种,占物种丰富度的78.14%。浮游植物的年平均细胞丰度为(7.01±6.26)×104 cell/L。骨条藻(Skeletonema sp.)和具槽帕拉藻(Paralia sulcata)为全年优势种,细长列海链藻(Thalassiosira leptopus)、碎片菱形藻(Nitzschia frustulum)、菱形缝舟藻(Rhaphoneis rhomoides)和梅尼小环藻(Cyclotella meneghiniana)为常见种。Shannon-Wiener多样性指数(H’)、Margalef 丰富度指数(D)和Pielous均匀度指数(J)全年均值分别为2.59±0.75、4.00±1.44和0.55±0.15。硅藻商全年均值为1.06±0.20。冗余分析(RDA)表明对该水域浮游植物影响较大的环境因子是盐度、水温、溶解氧和悬浮物浓度。
英文摘要:
      Xiao Yangshan is located on the north of Yangshan port, which is the first offshore deepwater port in China. Phytoplankton community structure of Xiao Yangshan sea area was investigated and analyzed from January to December in 2012. A total of 183 phytoplankton species, belonging to 7 phyla and 77 genera, were identified. Diatom, including 51 genera and 143 species which accounted for 78.14% of species richness, was the main phytoplankton group.The annual average cell abundance of phytoplankton was (7.01±6.26)×104 cell/L. Skeletonema sp. and Paralia sulcata were the main dominant species through the year, while Thalassiosira leptopus, Nitzschia frustulum, Rhaphoneis rhomoides and Cyclotella meneghiniana were the common species. Based on analysis of diversity, the annual average values of Shannon-Wiener index, Margalef index and Pielous index were 2.59±0.75, 4.00±1.44 and 0.55±0.15, respectively. The average number of Diatoms Index was 1.06±0.20. Redundancy analysis (RDA) showed that salinity, water temperature, dissolved oxygen and suspended solids concentration were the main environmental factors with great influences on phytoplankton.
