摘要
城市饮用水水源地安全在促进经济发展和稳定社会方面具有重要作用。目前,水源地安全综合评价在研究方法、研究内容方面都需要改进。以《全国城市饮用水水源地安全保障规划技术大纲》为基础,从水量、水质、管理水平和环境状况等方面,构建了基于三角模糊函数的城市饮用水水源地安全评价模型,并以河南省安阳市为例进行了研究。结果表明:安阳市10处城市饮用水水源地安全程度在一般之上,且隐患等级不同。安阳市第二、第三水厂水源地安全程度很高,均不存在较高、极高隐患,岳城水库等7个水源地安全程度较高,隐患等级具有明显差别,滑县第一水厂水源地安全程度一般。指标层、准则层对于水源地安全敏感性影响各不相同。水源地盈利情况是指标层中影响岳城水库水源地安全的首要因子,而环境因子则是准则层中最为敏感的因素。结论表明研究构建的指标体系和研究模型对于我国城市饮用水水源地安全评价具有一定的借鉴意义。
Urban drinking water sources have an important role in the promotion of social and economic development and stable social order, its comprehensive assessment should be improved in research methods and content. On the basis of " Urban Drinking Water Sources Protection Planning Technology Security Framework" , the paper has selected the operable and available 14 indexes of surface water source and 12 indexes of ground water source in terms of water quanti- ty, water quality, management and environmental conditions. Security assessment model of ur- ban drinking water sources was built based on triangular fuzzy numbers. Taking Anyang city of Henan Province as an example, the potential danger rank values and security level of the urban drinking water sources were evaluated compressively. Results show the security level of 10 urban drinking water sources in Anyang city is above average and the potential danger rank values are different. The security degree of the No. 2 and No. 3 waterworks in Anyang city is very high, without existence of higher potential danger and extremely high potential danger. Seven water sources such as Yuecheng Reservoir, Gongshang Reservoir have high security de- gree, but their potential danger degrees have evident differences, of which the No. 1 and No. 4 waterworks in Anyang city assign about 50% to low potential danger, but the No. 2 Waterworks in the Huaxian County and the water supply company in Tangyin County and Neihuang County assign about 30% to high potential danger, eventually the No. 1 Waterworks in Huaxian County has medium security and assigns only 35% to low security hidden danger and 29% to high secu- rity hidden danger. The factors of index layer and rule layer have different influences on the se- curity urban drinking water sources. The profitability of the urban drinking water sources in the index layer is the primary factor influencing Yuechening Reservoir, however, the environmental factor is the most sensitive factor influencing Yuecheng Reservoir. The conclusions sho
