摘要
2004-2009年对渤海湾鱼虾贝产卵场(天津区域)水体实施连续调查监测,对该水域水质的年代变化趋势和质量状况进行研究和综合评价。结果表明,渤海湾鱼虾贝产卵场(天津区域)水质处于波动状态,2004年、2006年、2008年水质质量相对较好,2005年、2007年、2009年水质污染较重;有机污染严重,已达到高富营养化程度。水质中主要污染物为石油类、化学需氧量,无机氮、活性磷酸盐是造成水体富营养化的关键因子。
In order to protect Bohai Bay fishery eco-environment and bio-resources,water quality status of fish,shrimp and shellfish spawning grounds in coastal Tianjin were researched and successively monitored in the past five years.Water quality variation trend and quality status were also evaluated and comprehensively assessed.The results showed that the water quality in fish,shrimp and shellfish spawning grounds in coastal Tianjin was in a volatile state with good water quality in the years of 2004,2006 and 2008.However,in the years of 2005,2007 and 2009,water quality was seriously polluted,especially the organic pollution,already within a high degree of eutrophication.The main pollutants were oil,inorganic nitrogen and active phosphate,the key factors of eutrophication in water.
