【目的】调查及评价钦州湾近岸海域水质污染程度。【方法】2010年3月（春季）及2010年9月（秋季）在钦州湾近岸海域布设9个站位进行水质、浮游植物及浮游动物调查。采用水质综合污染指数及生物多样性指数对调查结果进行评价。【结果】钦州湾近岸海域春季、秋季水质综合污染指数平均值分别为3．20、3．68；浮游植物多样性指数分别为3．37、3．35；浮游动物多样性指数分别为2．33、2．89。【结论】以水质综合污染指数评价，2010年钦州湾近岸海域污染等级为轻污染；以浮游植物多样性指数评价，污染等级为轻度污染至无污染；以浮游动物多样性指数进行评价，污染等级为轻中污染。相对于浮游动物多样性指数，浮游植物多样性指数能更灵敏地指示和评价海洋环境的污染形势，但其评价标准和方法有待更多的调查和研究来进行验证和修正。单一利用生物多样性指数进行海域污染评价，具有一定的局限性，但仍可在一定程度上反映出海洋环境的污染程度。

[Objective]The pollution status of Qinzhou bay coastal waters was investigated and assessed.[Methods]Night stations were set up and two cruises were carried out to investigate the water quality,phytoplankton and zooplankton status in Qinzhou Bay coastal waters in March 2010 (spring)and September 2010(autumn).Water comprehensive pollution index and biodiversity index (including phytoplankton and zooplankton)were used to assess the pollution status.[Results]The mean value of water comprehensive pollution index in Qinzhou Bay coastal waters in spring and autumn were 3.20 and 3.68,respectively.The mean value of phytoplank-ton diversity index in Qinzhou Bay coastal waters in spring and autumn were 3.37 and 3.35,re-spectively.The mean value of zooplankton diversity index in Qinzhou Bay coastal waters in spring and autumn were 2.33 and 2.89,respectively.[Conclusion]The pollution grade of Qinzhou Bay coastal waters by the method of water comprehensive pollution index,phytoplank-ton diversity index and zooplankton diversity index were light pollution,light pollution to non pollution and light-middle pollution,respec- tively.Relative to the zooplankton diversity in-dex ,the marine environmental pollution status can be indicated and assessed more sensitive by the method of phytoplankton diversity index,but the standard and methods should be verified and modified by more investigation and study in the future.There was limitation to assess of the pol-lution status by single biodiversity index,howev-er,the pollution level of the marine environment can be reflected to some extent.
