摘    要:根据2011~2013年夏季对靖海湾松江鲈鱼种质资源保护区表层海水营养盐、重金属以及相关环境因子的连续调查数据,分析了该调查区域近3年来海水环境质量的变化,并对该水域营养水平、重金属和有机污染状况进行了评价。结果表明,2011年重金属含量均符合一类海水水质标准,2012年Pb平均含量为1.1%g/L,2013年Cu、Pb、Hg平均含量分别为5.19、2.79、0.07μg/L,均超出一类海水水质标准。2011年和2012年N/P值均大于Redfield比值,P相对缺乏。根据营养化评价模式,调查海域2011年营养水平属磷限制潜在性富营养,2012年营养水平属中度营养,2013年营养水平属富营养化。2011年和2013年的有机污染指数均大于4,表明靖海湾受到严重的有机污染,DIN和PO4-P是靖海湾表层海水的主要污染物。2012年海水质量属于允许级别,2011年和2013年海水质量属于轻度污染,这与陆源排放、海水养殖等多方面因素有关。

关 键 词:靖海湾  综合评价  重金属  营养盐

Abstract:Based on the continuous surveys of heavy metals, nutrients and related environ mental factors of surface water in Trachidermus fasciatus Heckel germ plasm resource protection area in Jinghai Bay from 2011 to 2013, the variation of water quality was analyzed, and the nutrient level, heavy metals and organic pollution status were evaluated. The concentrations of heavy metals were below the limit of the first class seawater in 2011, and Pb concentration ex ceeded the first class seawater limit in 2012. In 2013, the concentrations of Cu, Pb and Hg were 5.19, 2.79 and 0.07 μg/L respectively, all above the limit of the first class seawater. In 2011 and 2012, N/P values were higher than the Redfield ratio of 16, indicating that phosphate was relatively deficient compared to nitrogen. Based on the eutrophication evaluation model, the surveyed area belonged to phosphorus-limiting potential eutrophication in 2011, moderate eu trophication in 2012 and eutrophication in 2013. The organic pollution index was higher than 4 in 2011 and 2013, indicating that the surveyed area suffered from serious organic pollution. DIN and PO4-P were the major pollutants of the surface water in Jinghai Bay. The seawater quality belonged to the permitted level in 2012, while the water quality belonged to the light pollution level in 2011 and 2013 due to pollutants from terrestrialrunoffs and aquaculture etc.
Keywords:Jinghai Bay Comprehensive evaluation Heavy metals Nutrients
