摘要: 基于灾害风险理论和水环境安全概念内涵,利用层次分析法对山西省黄河流域水环境安全风险状况进行了综合评价。结果表明,黄河流经的9个地级市水环境安全风险等级划分为极高、高、中等、低、极低5个层次,在致灾因素的危险属性里,晋城和长治两市分属于极高和高危险等级,朔州市属于中等风险,这主要是由水质恶化所致;在承灾因子的暴露属性里,忻州市和朔州市分属于极高和高暴露等级,晋中市和临汾市则属于中暴露等级,这主要是由水量减少、人口密度增加所致;在承灾因素脆弱属性里,运城市属于极高等级,晋城市和临汾市则属于高脆弱等级,属于中等脆弱性的是吕梁和朔州两市,这主要是由降水减少、人均水资源量不足所致。最后,通过综合分析,发现晋城市的总体风险最高,需要相关部门重点关注。

Abstract: Based on the disaster risk theory and the concept of water environment security, the risk situation of water environment security in the Yellow river basin of Shanxi province was evaluated by AHP. The results showed that the water environment safety risk levels of the nine prefectural-level cities along the Yellow river were divided into five levels:Extremely high, high, medium, low and extremely low, Jincheng city and Changzhi city were classified as very high and high risk, while Shuozhou city was classified as medium risk, mainly due to deterioration of water quality. Xinzhou city and Shuozhou city were classified as very high and high risk, respectively, in the exposure attribute of hazard-bearing factors, Jinzhong city and Linfen city were in the middle, mainly due to reduced water supply and increased population density; Yuncheng city was at the very high level of vulnerability, while Jincheng city and Linfen city were at the high level of vulnerability, among the medium vulnerable were the cities of Lyuliang city and Shuozhou city, mainly due to reduced precipitation and insufficient water resources per capita. Finally, through the comprehensive analysis, it was found that the Jincheng's overall risk was the highest, and the relevant departments needed to focus on.
