| 摘 要： | 以珠江广州河段(雅岗大桥至琶洲大桥)水体富营养化状况为调查对象,布设6个采样监测点,检测分析叶绿素a、总氮、总磷、透明度及CODMn等污染指标,采用综合营养状态指数法评价该河段枯水期富营养化程度。结果表明,珠江广州河段枯水期处于重度富营养状态,主要污染物TP、TN和CODMn浓度均值超过国家《地表水环境质量标准》的V类水标准,属地表水劣V类水体。珠江上游的渔业养殖、周边城市的工业排放与广州市区生活污水是造成水体污染的主要原因,联防联治长效机制的建立将有助于珠江水环境问题的解决。

| Abstract: | With eutrophication status of the Pearl River Guangzhou Section（from Yagang Bridge to Pazhou Bridge） as investigation objects,arranging 6 sampling monitoring plots,chlorophyll a（chla）,total phosphorus（TP）,total nitrogen（TN）,secchi disk depth（SD）and CODMn were detected and analyzed,comprehensive nutrition state index method was adopted to evaluate eutrophication degree in drought period.The results showed that： Guangzhou section of the Pearl River is in serious eutrophication during the dry season.Average concentration of the main pollutants chla,TP,TN,SD and the CODMn were inferior to water quality standard V grade of surface water.Aquaculture on upper reaches of the Pearl River,industrial emissions from surrounding cities and urban sewage from Guangzhou is the main reason of water pollution.The establishment of combined prevention and abatement long-term mechanism will help to solve the problem of environmental pollution in the Pearl River water. |
