普兰店湾海水交换和污染物COD扩散能力的再探

The Further Research on Seawater Exchange and Diffusion Ability of Pollutant COD of Pulandian Bay in Dalian

以2013年7月水文和化学要素的环境调查资料为基础,通过观测水文要素数据,建立了普兰店湾海域的平面二维潮流数学模型,在该模型基础上做了对普兰店湾水交换能力和污染物的扩散能力分析。在此基础上,将此湾划分成6个区域,采用关联矩阵的方法研究和计算了化学污染物在各区的扩散能力,得出6个区域COD扩散能力的交换新结论,其表现特征是C区>E区>B区>A区>D区>F区。再从环境地球化学保护角度考虑,提出在该海湾上游应严格控制COD入海的排放及海洋环境保护新探索。

This paper is based on environmental survey of hydrological and chemical elements in July 2013. established 2D Tide flow numerical model of Pulandian Bay in Dalian by using the observation da- ta of hydrological elements, analysed water exchange capacity and pollutant diffusion ability on the ba- sis of this model, based on this research,divided Pulandian Bay into 6 regions,by using method of inci- dence matrix research and calculate the chemical pollutants diffusion ability and drawing the new con- clusion of COD diffusion capacity, as C〉 E〉B〉 A〉D〉 F. Then from the perspective of environmental geochemistry protection,Put forward that should strictly control the emissions of COD into the sea in the upstream and other new exploration of marine environmental protection of Pulandian Bay in Dalian.
