摘　　要：基于2012年对雷州半岛近岸水域海洋环境调查的结果,对其近岸海水水质进行评价。各因子一类海水平均达标率为75.12%。Cd、Cr6+、Zn、As和挥发性酚的一类海水达标率为100.00%;Hg的一类海水达标率最低,为11.67%;P、Pb、悬浮物的达标率也偏低,分别为45.00%、56.67%和58.33%。雷州半岛西南部近岸海域水质最好,西部海域水质好于东部。东部水域中,雷州湾水质好于湛江港和新寮湾。雷州半岛轻污染水域较多,湛江港、新寮湾附近海域水质最差。Based on the Leizhou Peninsula coastal marine environment investigation in 2012, the near shore water quality was evaluated. The average compliance i：ate of the assessment factors is 75.12%. First - class sea water compliance rates of Cd, Cr^6＋ , Zn, As and volatile phenol are 100.00%. The lowest compliance rate factor is Hg with the compliance rate 11.67%. In addition, compliance rates of P, Pb and suspended matter are low to 45%, 56.67% and 58.33% respectively. The best water quality region is in the southwest. Water quality in the west coast is better than that in the east coast. In the east, water quality in Leizhou Bay is better than that in Zhanjiang Port and Xinliao Bay. Lightly polluted water covers large areas of Leizhou Peninsula, and the most heavily polluted regions are Zhanjiang Port and Xinliao Bay.
