选用2011年大连湾附近海域的监测数据，分别采用不同的评价方法对大连湾海域的水质现状加以评价。并依据2007-2011年该海域连续五年的监测数据，对其污染趋势加以分析。结果表明：大连湾海域内主要污染物为无机氮，湾内各监测点均处于富营养化状态，受有机物污染严重。陆源排污是该海域受到严重污染的主要原因。五年来除无机磷外其余各因子均有不同程度的污染加重的趋势，其中以石油类的加重趋势最为显著。

in this paper ,according to the monitoring data of Dalian bay waters near 2011 ,different e-valuation methods were used respectively to evaluate the water quality situation of Dalian bay waters . And according to the 2007-2011 for five consecutive years of monitoring data ,the waters of the ocean pollution trend analysis .The results show that the main pollutants are inorganic nitrogen in sea ,bay are in a state of eutrophication of the monitoring ,the organic matter pollution .The main pollution factor from the terrigenous pollution .In addition to the inorganic phosphorus in five years the rest each factor has different degrees of pollution in trend ,with the increasing trend of dissolved oxygen in the most significant .
