Assessment on Water Environmental Quality in Offshore Area of Dongguan and Analysis on Its Changing Trend

Fund Project:

摘要: 采用污染分担率法确定污染因子,应用综合污染指数法对2004~2009年东莞市近岸海域水环境质量进行全面评价,并运用秩相关系数法分析其变化趋势。结果表明:COD_Mn、磷酸盐、无机氮、汞是影响东莞近岸海域水环境质量的主要因子;东莞市近岸海域水环境质量由上游到下游基本呈现依次下降的特征;从2004~2009年,近岸海域环境质量总体呈现好转的态势。

Abstract: The paper uses the pollution sharing rate to determine the pollution factors and applies the intergrated pollution index to give the comprehensive assessment of offshore area of Dongguan and analyzes the changing trend from 2004 to 2009.The results show:COD_Mn,phosphate,inorganic nitrogen and mercury were major factors to affect the water environmental quality in offshore area of Dongguan.And its water environmental quality from head waters to lower reaches presented the character of more and more serious pollution.From 2004 to 2009,the water environmental quality in offshore area of Dongguan was taking a turn for the better.
