摘要
结合近20 a来珠江三角洲地区经济发展状况,对多年来珠江口海域水质监测数据进行统计分析。结果表明:珠江三角洲地区工业化、城市化进程加快以及人口迅速膨胀所产生的污水排放量增加,是导致珠江口海域水质恶化的主要原因。采用综合指数法进一步对珠江口海域水质进行评价,结果发现:珠江口海域20 a来综合污染指数出现高一低一高的变化模式,与同期珠江三角洲工业污水处理率的提高而生活污水处理滞后相对应,也表明,珠江口海域水质污染已从20世纪80年代初期的工业污染类型转变成生活污染类型。
Based on the twenty years data on the economic developments in the Zhujiang Delta area, the amount of pollutants into the Zhujiang Estuary and the monitoring data of the water quality in the Zhujiang Estuary were analyzed. The results show that the amount of the sewage increased with the industrialization, the being citified and the rising population is key causes. Using the composite index number (CIN) to assess the water quality in the Zhujiang Estuary, the CIN are high-low-high in last 20 years,and the more sewage into the Zhujiang Estuary, and the water quality was worse and worse.
