【摘要】:根據(jù)目前公認(rèn)的水安全內(nèi)涵,將水安全分為三個子系統(tǒng)。水資源子系統(tǒng)、水環(huán)境子系統(tǒng)和水災(zāi)害子系統(tǒng)。三者相互聯(lián)系、相互作用,形成了復(fù)雜、時變的水安全系統(tǒng);谒踩幕驹砗涂λ固貐^(qū)域特有的水循環(huán)機理,依據(jù)"驅(qū)動力(D)—壓力(P)—狀態(tài)(S)—影響(I)—響應(yīng)(R)"模型建立了貴州省喀斯特區(qū)域水安全評價指標(biāo)體系;诩瘜Ψ治隼碚,引入能夠體現(xiàn)系統(tǒng)確定性和不確定性的同異反聯(lián)系度計算公式,建立了城市水安全的評價模型。將集對分析法運用到水安全的評價中,可以先通過計算評價樣本與評價指標(biāo)之間的聯(lián)系度對樣本作初步的排序,再對樣本作進(jìn)一步的同一、差異、對立的集對分析,以判斷出評價樣本的等級。研究結(jié)果表明:(1)在水資源安全狀態(tài)方面,貴州省9個州市中4個處于安全狀態(tài),2個處于基本安全狀態(tài),2個處于不安全狀態(tài),1個處于危機狀態(tài);(2)在水環(huán)境安全狀態(tài)方面,2個處于安全狀態(tài),4個處于基本安全,3個處于不安全;(3)在水災(zāi)害安全狀態(tài)方面,1個處于非常安全,4個處于安全,1個處于基本安全,2個處于不安全,1個處于危機;(4)在水安全綜合狀態(tài)下,有3個處于安全狀態(tài),有4個處于基本安全狀態(tài),有2個處于不安全狀態(tài),沒有處于非常安全和危機狀態(tài)。
[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.
