摘要
根据2000年和2001年的调查资料,分析研究了莱州湾浮游植物分布特征。发现枯水期间以角毛藻和斯氏根管藻为主要优势种类,丰水期间以角毛藻、骨条藻、佛氏海毛藻等为主要优势种类。总量平面分布极不均匀,枯水期间密集区在西部近岸水域,丰水期间密集区由近岸扩展至中部水域。总量变动与无机氮含量密切相关。枯水期间近岸水域内多样性较差。
Based on the data obtained in the survey in Laizhou Bay from 2000 to 2001, the distribution characteristics of phytoplankton are analysed and discussed in this paper. The results show that Chaetoceros spp. and Rhizosolenia. stolterfothii Peragallo are the dominant species in the dry season and Chaet. spp . Skeletonema costatum(Greville)Cleve. Thalassiothrix frauenfeldii Grunow in the wet season. The sum of phytoplankton at each station varies significantly. The concentration area is found in the west near the shore in the dry season but it expands to the middle of the bay in the wet season. The variety of phytoplankton amount is related closely with the inorganic nitrogen contained in the water. In the water near the shore the diversity index is smaller in the dry season than in the wet season.
