为了对城市水安全进行科学有效的评价,通过分析影响水安全的各个因素及各因素之间的相互联系,建立了较为合理的水安全评价指标体系,并给出了各相关安全因素的权重;运用模糊数学法建立了水安全评价模型,对咸阳市的水安全做出了科学合理的安全分析评价。2007年咸阳市总体水安全状态为基本安全,但生态环境处于很不安全的状态,应采取相应措施来加强环境保护和保证城市水安全。经过与实际情况对比分析得出,采用模糊综合评价方法进行城市水安全评价是合理可靠的。
In order to evaluate the safety of urban water scientifically and effectively, a more reasonable index system of water safety assessment is established by analyzing the various factors affecting water safety and the interrelation among the factors, and the weight of each safety factor is given. The fuzzy mathematics method was used to establish the water safety evaluation model and to make a scientific and reasonable safety analysis and evaluation of water safety in Xianyang City. In 2007, the general state of water security in Xianyang City is basic safety, but the ecological environment is in a very unsafe state. Corresponding measures should be taken to strengthen environmental protection and ensure urban water security. After comparing with the actual situation, it is concluded that the evaluation of urban water security by fuzzy comprehensive evaluation method is reasonable and reliable.
