摘　　要：不同理化性质的水团影响浮游动物种类组成和群落结构。为了探讨吕宋海峡的环境对浮游动物群落结构的影响,于2008年8月15日至9月15日对吕宋海峡浮游动物的种类组成和丰度分布进行了调查和分析。共鉴定出浮游动物257种和浮游幼虫12个类群,吕宋海峡西部海域浮游动物种类数和多样性比中东部海域的高。浮游动物平均丰度为(16.76±11.36)ind./m3。其中,吕宋海峡西部海域浮游动物平均丰度高于吕宋海峡中东部海域。聚类分析结果表明,吕宋海峡浮游动物可分为两个类群,一类为分布于吕宋海峡的中东部,受黑潮水影响的类群;另一类为分布于吕宋海峡西部,受南海水影响的类群。吕宋海峡浮游动物群落结构反映了该海域浮游动物的种类组成和分布受不同性质水团的调控。Different water masses have distinct natural physical and chemical properties, which may influence the zooplankton community structure. In order to improve our understanding of the relationship between zooplankton and water mass, zooplankton was sampled at 14 stations between 15th August, and 19th September, 2008 in the Luzon Strait. A total of 257 species and 12 groups of planktonic larvae were identified. Copepod was the most dominant species, followed by medusa. Species richness and diversity indices in the west of Luzon Strait were higher than that in the east of Luzon Strait. The average abundance of zooplankton in Luzon strait was 16. 76 11.36 ind./m3. Zooplankton abundance in the west of Luzon Strait was higher than that in the east of Luzon Strait. Cluster analysis showed that there was difference in zooplankton community between the both sides of Luzon strait. The differences of zooplankton communities indicated that different water masses can influences zooplankton species composition and spatial distribution.
