珠海饮水安全问题不仅与珠海市经济社会可持续发展紧紧相连,而且关系到澳门特区的供水安全。根据污染物排放理论及标准,应用数学统计与GIS技术手段对珠海市饮用水源地纳污范围内污染源进行调查评价,得出珠海市水源地以生活点源与面源为主要污染源。根据各水源地的污染源构成差异,将水源地分成生活污染源型、面源污染型和混合污染型,针对不同污染类型提出适合于各水源地的治理与改善措施。
The issue of drinking water safety in Zhuhai is not only closely linked to the sustainable economic and social development in Zhuhai, but also relates to the water supply safety of the MSAR. According to the theory and standard of pollutant discharge, the author uses mathematical statistics and GIS techniques to investigate and evaluate the sources of pollutants in the drinking water sources of Zhuhai City. The results show that the point sources of life and surface sources of Zhuhai are the main sources of pollution. According to the differences of pollution sources among different water sources, the water sources are divided into living pollution source, non-point source pollution source and mixed pollution source. According to different types of pollution, the measures for improvement and improvement are put forward.
