灌河口附近海域水质状况调查研究

Water Quality Investigation Research in Guan River Sea Area

近海水域的水环境对沿海城市的可持续发展具有重要意义。根据2006年4、5月灌河口附近海域水质监测资料,对海域的水质状况进行了分析和评价研究。结果表明：pH符合《海水水质标准》（GB3097-1997）Ⅰ类水质标准,DO、COD符合Ⅰ、Ⅱ类水质标准;油类含量的平均值在0.031-0.062 mg/L间变化,水质符合Ⅰ、Ⅱ类水质标准;油类含量符合Ⅰ、Ⅱ类水质标准;无机氮和活性磷酸盐含量已经超过Ⅲ、Ⅳ类水质标准;灌河口附近特殊的潮流场及苏北沿岸流对污染物质的空间分布格局的影响较大,建议对该海域进行大规模的水文监测分析,加强对海域环境的科学管理,以便及时采取对策。

Inshore water environment plays a very important role in coastal cities＇ sustainable development.Based on the monitoring result of water quality in Guan river sea area from April to May in 2006,the assessment on the seawater quality in the region was done,The results show： The contents of pH is coinciding with the 1st class seawater quality standard of GB3097-1997;The contents of DO and COD are according with the 2 nd class seawater quality standard;The average contents of oils arranges from 0.031 to 0.062 mg/L,which is accordance with the 2nd class water standard.Inorganic nitrogen and phosphate are beyond 3rd and 4th class water standard.Tidal current and coastwise current about Guan river have an effect on contaminations distribution.The relevant sectors and departments should take measures to serve people such as hydrology inspection on a large scale and scientific government.
