主 题：Centralized drinking water source Drinking water safety Lakes and reservoirs Population Water quality
摘 要：Drinking water is closely related to human health,disease and mortality,and contaminated drinking water causes 485,000 deaths from diarrhea each year *** has been facing increasingly severe water scarcity due to both water shortages and poor water *** safe and clean drinking water is a great challenge and top priority,especially for China with 1.4 billion *** China,more than 4000 centralized drinking water sources including rivers,lakes and reservoirs,and groundwater have been established to serve urban ***,there is little knowledge on the percentage,serving population and water quality of three centralized drinking water source *** collected nationwide centralized drinking water sources data and serving population data covering 395 prefecture-level and county-level cities and water quality data in the two most populous provinces(Guangdong and Shandong)to examine their contribution and ***,the drinking water source types can be classified into three clear regions exhibiting apparent differences in the respective contributions of rivers,lakes and reservoirs,and *** further found that overall,lakes and reservoirs account for 40.6%of the centralized drinking water sources ***(30.8%)and groundwater(28.6%)in *** and reservoirs are particularly important in the densely populated eastern region,where they are used as drinking water sources by 51.0%of the population(318 million).Moreover,the contribution to the drinking water supply from lakes and reservoirs is increasing due to their better water quality and many cross-regional water transfer *** results will be useful for the government to improve and optimize the establishment of centralized drinking water sources,which provide safe and clean drinking water in China to safeguard people s lives and health and realize sustainable development goals.
