摘　　要：全球气候变化背景下湖库型水源面临不同程度的富营养化与蓝藻水华问题,对饮用水安全供给产生重要影响。本文通过分析我国现阶段湖库富营养化与湖库型水源地水质现状,从水源保护、净化工艺、管网配送与保障机制等方面,研判了全球气候变化背景下我国湖库型饮用水水源富营养化应对与饮用水安全保障面临的问题与挑战,提出四条针对性的饮用水安全保障策略建议:加强湖库型饮用水水源地环境保护与生态修复力度、推动全过程饮用水安全保障的科技支撑体系建设、构建基于大数据融合的饮用水安全保障智慧化监管平台、加快推动湖库型饮用水源水质安全保障体制机制创新,以期为气候变化影响下我国未来饮用水安全保障提供借鉴。Lake and reservoir ecosystems face varying degrees of eutrophication and cyanobacterial bloom against the background of global climate change,which threatens the safety of drinking water supply.In this study,we reviewed the current status of eutrophication and water quality of lake and reservoir water sources in China,and explored the challenges from the aspects of water source protection,purification process,pipe network distribution,and guarantee mechanism.Four targeted suggestions were recommended for guaranteeing drinking water safety:(1)strengthening environmental protection and ecological restoration of lake and reservoir drinking water sources,(2)promoting the construction of a scientific and technological support system for guaranteeing drinking water safety in the entire process,(3)building an intelligent supervision platform based on big data fusion,and(4)accelerating the system and mechanism innovation for guaranteeing lake and reservoir drinking water safety.
