摘　　要：地下水作为人类生存空间的重要组成部分,为人类提供了优质的淡水资源。因其对人们的生活和经济的发展具有重要的作用,而被广为利用。然而,地下水水质日益面临来自农业、工业和生活污染源的威胁。通过对杭州市主城区浅层地下水监测发现,水质"三氮"超标现象普遍,主要超标项目为氨氮、亚硝酸盐氮、高锰酸盐指数和总大肠菌群及细菌总数,这跟主城区地下水长期受生活污水、企业工业废水、农业面源污染有直接关系。为了防止杭州市主城区浅层地下水水质进一步恶化,通过调研提出:加强地表水、地下水污染防治,加强地下水监测网络建设,控制浅层地下水对深层地下水的影响,同时加强地下水资源的保护宣传教育工作等办法。Goundwater,which is the important component of the human living space and supplies human being high-quality freshwater,is widely used because of its importance for human life and the economic development.However,quality of ground water has been threatened by pollution from agriculture,industry and everyday life.Through the monitoring of shallow ground water of main districts in Hangzhou City,we found that nitrogen compounds exceed the standard widespreadly,including ammonia nitrogen,nitrite nitrogen,permanganate index and total coliform and total bacteria.This is mainly related with long-term pollution from life,industry and agriculture.Through the research and on-site monitoring,this paper raised some countermeasures to avoid further contamination on shallow groundwater in main districts of Hangzhou City,which includes enhancing surface water and groundwater pollution prevention and control,enhancing groundwater monitoring network construction,strengthening the protection of groundwater resources,publicity and education work.
