摘　　要： 为了解大亚湾附近海域海洋环境质量状况,本文对该海域的海水水质、沉积物以及海洋生态的初级生产力进行了研究与评价。研究结果表明,监测海区海水中化学耗氧量(CODMn)和总悬浮物(SS)含量较高,除部分监测海域站位中铅、砷含量超过海洋水质第一类标准外,未出现明显重金属污染;在8个监测海区中,沉积物的铜、铅、锌、铬含量均较低,只在中部缓冲区S4站出现镉超过海洋水质第一类标准现象。 This study aimed to gain a clear understanding the marine environmental quality of the attached sea area of Daya Bay. Research and evaluation of seawater quality, sediments and primary productivity of marine ecology were conducted in the sea area. Results showed that seawater had high chemical oxygen demand(CODMn) and total suspended solids(SS). There is no obvious heavy metal pollution in seawater, except for the Pb and As content in some monitored sea areas exceeding the first standard of marine water quality. For sediments, Cu, Pb, Zn and Cr were all low in the eight monitored sea areas, and Cd in the central buffer zone S4 station exceeded marine water quality first standard.
