根据2004-2010年北部湾防城港近岸海域的水质监测数据，对北部湾防城港近岸海域的海水环境参数变化与水质状况进行评价。检测海水环境参数：化学需氧量、无机氮、活性磷酸盐、溶解氧、石油类和重金属的变化情况。结果表明，北部湾防城港近岸海域水质状况总体良好，存在的主要超标因子是无机氮和活性磷酸盐，其中北仑河口主要受到无机氮污染，防城湾主要的污染物是活性磷酸盐，珍珠湾水质较清洁，市政排污、养殖排污和工业排污是防城港近岸海域的主要污染来源。近岸海域化学需氧量、无机氮和活性磷酸盐均呈现明显上升趋势，其中无机氮和活性磷酸盐年均值增长较快，由此说明北部湾防城港近岸海域水质污染程度正逐步加大，需引起足够重视。

The water quality of Beibu Gulf Fangchenggang Inshore was analyzed and evaluated based on the monitoring results in 2004-2010. The results showed that the quality of water in Beibu Gulf Fangchenggang Inshore is generally high. Inorganic nitrogen and active phosphate are the main factor over the standard. Beilun port was mainly affected by inorganic nitrogen pollution and Fangcheng Bay was mainly polluted by active phosphate,while less pollution was detected in Pearl Bay. The increase of COD, inorganic nitrogen and active phosphate,especially the rapid increase of last Gulf Fangchenggang Inshore dramatically tection of water quality. two indexes,indicated that the pollution in Beibu increased, which required more attention for protection of water quality.
