【摘要】：根据目前公认的水安全内涵,将水安全分为三个子系统。水资源子系统、水环境子系统和水灾害子系统。三者相互联系、相互作用,形成了复杂、时变的水安全系统。基于水安全的基本原理和喀斯特区域特有的水循环机理,依据"驱动力(D)—压力(P)—状态(S)—影响(I)—响应(R)"模型建立了贵州省喀斯特区域水安全评价指标体系。基于集对分析理论,引入能够体现系统确定性和不确定性的同异反联系度计算公式,建立了城市水安全的评价模型。将集对分析法运用到水安全的评价中,可以先通过计算评价样本与评价指标之间的联系度对样本作初步的排序,再对样本作进一步的同一、差异、对立的集对分析,以判断出评价样本的等级。研究结果表明:(1)在水资源安全状态方面,贵州省9个州市中4个处于安全状态,2个处于基本安全状态,2个处于不安全状态,1个处于危机状态;(2)在水环境安全状态方面,2个处于安全状态,4个处于基本安全,3个处于不安全;(3)在水灾害安全状态方面,1个处于非常安全,4个处于安全,1个处于基本安全,2个处于不安全,1个处于危机;(4)在水安全综合状态下,有3个处于安全状态,有4个处于基本安全状态,有2个处于不安全状态,没有处于非常安全和危机状态。
[Abstract]:According to the accepted connotation of water safety, water security is divided into three subsystems: water resources subsystem, water environment subsystem and water disaster subsystem. Time-varying water security systems. Based on the basic principles of water security and the unique mechanism of water circulation in karst regions, Based on the model of "driving force, pressure, pressure, state, influence, I and response," an evaluation index system for water safety in karst area of Guizhou Province is established. Based on the theory of set pair analysis, the evaluation index system of water safety in karst area of Guizhou Province is established. An evaluation model of urban water safety is established by introducing the calculation formula of similarity, difference and inverse relation, which can reflect the certainty and uncertainty of the system, and the set pair analysis method is applied to the evaluation of water safety. We can first make a preliminary ranking of the samples by calculating the degree of connection between the evaluation samples and the evaluation indicators, and then make a further analysis of the same, different, opposing set pairs of the samples. To determine the grade of the evaluation sample. The results of the study show that: 1) in terms of the state of water resources security, 4 out of 9 cities in Guizhou Province are in a safe state, 2 are in a basic state of safety, 2 are in a state of insecurity, 1 is in a state of crisis, 2 are in a safe state of water environment, 2 are in a state of safety, and 4 are in a basic state of safety. Three are in unsafe conditions, one is very safe, four are safe, one is basic security, two are unsafe, one is in crisis, and one is in a comprehensive state of water security. Three are in a safe state, four are in a basic security state, two are in an unsafe state, and are not in a very safe and critical state.
