夏季强降雨对胶州湾浮游硅藻群落结构的影响
The influence of heavy rainfall on the community structure of planktonic diatom in Jiaozhou Bay in summer
摘要
Abstract
To study the influence of heavy rainfall on diatom, the species composition, abundance and community structure of the diatom in Jiaozhou Bay were analyzed. The samples were collected on Jul.17, 2012 (before the rainstorm ) and Aug.5, 2012 (after the rainstorm ), and the influence of the rainstorm on diatom was discussed. 54 species of diatom belonging to 22 genera were identified before the rainstorm, , and only 38 species of diatom be-longing to 18 genera were recorded after the rainstorm. The species number of diatom decreased significantly. The average abundance of diatom was 2953.9×104 cells/m3 before the rainstorm. The main dominant species were Chaetoceros lorenzianus, Chaetoceros pseudocurvisetus, Coscinodiscus asteromphalus and Eucampia zoodiacus. After the rainstorm, the average abundance of diatom was 111.4×104 cells/m3, and the main dominant species were Cerataulina pelagica, Lithodesmium undulatum, C. asteromphalus and E. zoodiacus. The distribution pattern of diatom after the rainstorm changed obviously, and its horizontal distribution was more homogeneous after the rain-storm than that before the rainstorm. This research provided significant information about the influence of the un-usual environmental changes on diatom and phytoplankton.关键词
