摘要
为了解近年来珠江口水域的环境质量,及该水域与其邻近水域的环境质量差异,本文利用1993年有关环境调查数据,选用适当的评价模式,对主要污染物的特征值进行了统计、计算。根据水域的环境特点,划分出六个评价区,对主要污染物质进行分析、比较和评价,对各区水质进行综合评价。评价结果表明,珠江口及其邻近水域的主要污染物质为无机氮和油类。珠江口水域水质污染较其邻近水域严重;珠江口北部较珠江口南部水域水质差。
Using water monitoring data in 1993 ,the environmental quality of the Pearl estuary and its vicinity was analysed and assessed with an environmental quality index model. The result shows that the estuary has suffered grave pollution which is worse in the north than in the south of the estuary. The main pollutants are inorganic nitrogen and oil.
