Zoning security evaluation and countermeasures of urban drinking water sources for Chinese cities

Combined with the layout of social and economic development in eastern,central and western China,eight planning divisions were proposed based on comprehensive analysis of urban water supply composition,regional urbanization level,and the integrated per capita water consumption.Based on the results of surveying and analyzing urban drinking water sources in China,the distribution status of the urban drinking water sources in planned divisions was introduced,and the security situation of water quality and water quantity of the urban drinking water sources was comprehensively evaluated.The overall evaluation showed that the security situation of urban drinking water sources for Chinese cities was at risk,and there existed significant regional differences in drinking water security characteristics and main problems among the planning divisions.An overall safety countermeasures layout of water sources in each planning division was proposed according to the results of zoning security evaluation of urban drinking water sources.
