Study on the Safety Assessment Index System of Lake-reservoir-type Drinking Water Sources
Drinking water safety is related to people's health and social stability,building safer water sources is a key de-velopment direction for water source protection in the new era.Based on the definition of water source safety,this paper conducts a bibliometric analysis with CiteSpace to explore the current hot trends in water source safety research,and propo-ses an assessment framework covering four aspects:water supply safety,water quality safety,risk and emergency response,and management safety;14 indicators included in the assessment system were identified through a frequency analysis and screening supplement of key literature indicators.An improved AHP-CRITIC weighting method was used to assign a combi-nation of subjective and objective weights,eliminating the subjectivity of a single assignment.The assessment system,which,reflects the comprehensive and completeness of water source safety,solved the problem that most previous studies have only focused on one aspect,such as water quality,and could better diagnose the unsafe factors in water sources.Ex-ample validation with Banqiao Reservoir,the results show that the safety assessment of Banqiao Reservoir is 90.78 points,which is at the safe level(Ⅰ),in which,the assessment level of water quality and management is safety(Ⅰ),those of water supply and risk and emergency response are safe but with minor risks(Ⅱ).The assessment results are generally consistent with reality,which indicates that the assessment system is reliable and practical.
