基于综合指数法的城市水安全评价

Evaluation of urban water security based on comprehensive index method

为客观衡量和评价城市水安全状况,综合考虑水安全概念及内涵、城市发展现状及趋势、水安全相关规划研究,建立了包括防洪安全、饮水安全、用水安全、河湖生态安全、涉水事务监管安全5个准则层、31项指标的城市水安全评价指标体系,采用指数型功效函数实现了评价指标的标准化,构建了城市水安全评价模型,并以湖南邵阳市为例开展了实证研究。结果表明,邵阳市水安全综合指数为0.6562,处于“基本安全”状态,与实际情况基本相符。

In order to objectively measure and evaluate the status of urban water security,taking into account the concept and connotation of water security,the present situation and trend of urban development,and the related planning and research of water security,an evaluation index system of urban water security was established,which included 31 indexes and five criteria layers,including flood control safety,drinking water safety,river and lake ecological safety,and wading affairs supervision safety.The index function was adopted to standardize the evaluation indexes,and an evaluation model of urban water security was constructed.Taking Shaoyang City,Hunan Province as an example,the empirical study shows that its comprehensive index of water security is 0.6562,which is in a“basic security”state,basically consistent with the actual situation.
