摘　　要：2004年7～8月在台湾浅滩周边水域进行了两个断面的水体悬浮物浊度、叶绿素a荧光调查，通过对该区域夏季悬浮物质浊度、叶绿素a荧光的分布变化特征研究，结合水文相关要素分析，初步揭示了该区域海洋沉积和再悬浮过程对悬浮体浊度、叶绿素a荧光分布的影响．悬浮物质浊度在近岸与陆架外缘主要受再悬浮作用影响，而浅滩区再悬浮作用不明显；在陆架外缘区浮游植物的聚集作用对浊度有一定的贡献作用，而近岸区则不明显．Two sections were investigated on the turbidity and fluorescence of suspended particulate matter（SPM） in waters around Taiwan Bank during July-August,2004. The study showed that the distribution of turbidity and fluorescence in Taiwan Bank in summer, combined with hydrology factors,was affected by the marine sediments re-suspension and sedimentary processes. The turbidity of SPM was influenced by the re-suspension of marine sediment in near shore and the outer fringe of continental shelf, but was not obvious in the shoal. The enrichment of phytoplankton had some effects on the turbidity in the outer fringe of continental shelf,but not evidence in near shore waters.
