摘要
参照《海水水质标准》(GB 3097-1997),采用修正灰色聚类法对2006-2007年珠海逐月近岸水质监测数据进行分析,综合评价珠海近岸水质状况。选择溶解氧、无机氮、活性磷酸盐、石油类、铜、铅、汞等12个评价指标进行评价。评价结果表明,前山河出海处污染最为严重,城市排水口对海水水质的污染不容忽视,其他监测点的水质也不同程度地受到无机氮、活性磷酸盐的污染。根据评价结果,对污染严重的地区走访调查,提出污水管网的完善、污水处理厂除氮脱磷效率的提高、杜绝企业及近岸服务业的违章排放是减少陆源污染的重要措施,指出加强近海养殖和航运的管理对减少近岸污染至关重要。
Consulting GB 3097 - 1997 sea water quality standard, this article analysis Zhuhai monthly coastal water quality monitoring data between 2006 and 2007 by modified Gray - clustering method. This article chose eleven indicators： dissolved oxygen,inorganic nitrogen, active phosphate, oil, copper,lead,mercury ect, and get comprehensive evaluation of coastal water quality in Zhuhai. Analysis the estimate results： that Qianshan river estuary was polluted most heavily. It is indispensa- ble that urban outfall carry contamination to seawater. The other monitoring points also polluted by in- organic nitrogen and active phosphate. According to the results of the evaluation of serious pollution to visit the region to investigate, pointing out that improving the sewer network, sewage treatment plants in addition to nitrogen dephosphorization efficiency, and put an end to business services sec- tor, the coastal regulations to reduce emissions from land - based sources of pollution is an important measure. The strengthening of coastal shipping and aquaculture management is essential to reduce coastal pollution.
