胶州湾浮游植物多样性及其与环境因子的关系

2003年6月对胶州湾水域中的浮游植物进行了调查，根据所获得的资料分析了胶州湾水域中浮游植物分布规律及优势种的组成、浮游植物多样性分布及浮游植物与环境因子的关系，结果表明：胶州湾浮游植物细胞数量及多样性分布受西部陆源污染的影响很明显；浮游植物中在细胞数量上占优势的种类有中肋骨条藻、劳氏角毛藻、加氏星杆藻、锤状中鼓藻及扭鞘藻；由于各种原因浮游植物与环境因子的相关性不是很明显。

Relation Between Diversity of Phytoplankton and Environmental Factors in the Jiaozhou Bay

In June 2003, we made an investigation of phytoplankton in the Jiaozhou Bay. According to the investigation data, we analyzed distribution, dominant species and diversity of phytoplankton and its relation with the environmental factors. The analysis results show that the distribution of biomass and diversity is markedly influenced by pollution from the terrestrial source in the west; dominant species are represented by Skeletonema costatum (Greville) Cleve, Chaetoceros lorenzianus Grunow, Astreionella kariana Grunow, Bellerochea malleus (Brightwell) v.Heurck, and Streptotheca thamesis Schrubsole; and relation between phytoplankton and environmental factors is not obvious due to various reasons.
