胶州湾海域富营养化水平与浮游植物多样性分析

在2011年对胶州湾主要营养盐调查的基础上,采用富营养化指数和生物多样性指数分别对胶州湾水体富营养化状况和浮游植物生境状况进行了分析。结果显示,2010年胶州湾富营养化严重的海域主要集中在胶州湾东北角及北部海域,呈现由北向南逐渐减轻的趋势。从季节变化来看,3月份整个海域富营养化程度最低,10月份富营养化程度最重。胶州湾浮游植物群落主要由硅藻和甲藻组成,胶州湾北部海域生境质量一般,其余海域生境质量优良。

Eutrophication Level and Phytoplankton Diversity in Jiaozhou Bay

Based on investigation of main nutrients in Jiaozhou Bay in 2011, the eutrophication status and phytoplankton community structure in this area were analyzed. The results showed that the most severe eutrophication mainly concentrated in the northeast of Jiaozhou Bay and the level of eutrophication decreased from north to south. From the perspective of seasonal changes, the lowest eutrophication level occurred in March, while the most severe eutrophication occurred in October. Phytoplankton community of Jiaozhou Bay mainly consisted of diatom and dinoflagellate, and the habitat quality of the northern waters was general and the rest was good.
