摘　　要：基于2019年春季(5月)和夏季(8月)在青岛近岸的现场调查,研究了青岛近岸浮游植物群落结构变化特征及其与环境相关性,分析了浮游植物群落结构形成及变化的原因。结果显示,青岛近岸海域春夏两季共鉴定出浮游植物109种,隶属4门52属。与历史同期资料对比,青岛近岸浮游植物群落出现明显的群落演替现象,中肋骨条藻(Skeletonema costatum)的优势地位下降。胶州湾浮游植物细胞丰度明显大于崂山近岸,夏季崂山近岸的多样性指数大于胶州湾。对浮游植物群落结构与环境因子进行相关性分析和冗余分析发现,浮游植物细胞丰度与磷酸盐、DIN呈极显著正相关关系(P<0.01),与COD呈显著正相关关系(P<0.05),与盐度、pH呈显著负相关关系(P<0.05)。A field survey was carried out in Qingdao coastal area in spring(May)and summer(August)in 2019.Variation characteristics of phytoplankton community structure in coastal areas of Qingdao and their relationship with environment were studied,and the reasons of variation were analyzed based on the historical data.The results showed that a total of 109 taxa which belong to 52 genera of 4 phyla were identified in spring and summer.Compared with the historical data,the survey results of the phytoplankton community in costal waters of Qingdao showed obvious species succession,and the dominance of predominant species,Skeletonema costatum,remarkably decreased.The cell abundance of phytoplankton in Jiaozhou Bay was significantly higher than that in Laoshan Bay,and the diversity index of Laoshan Bay was higher than that in Jiaozhou Bay in summer.Correlation analysis and redundancy analysis of phytoplankton community structure and environmental factors showed that the phytoplankton cell abundance showed a positive correlation with phosphate and DIN(P<0.01),the phytoplankton cell abundance showed a positive correlation with COD(P<0.05)while the phytoplankton cell abundance showed a negative correlation with salinity and pH(P<0.05).
