摘要
全球极端气候频发对大型城市用水安全构成威胁,旨在通过改进应急水源地选取和评价方法,提高选址效率和适宜性,确保紧急情况下满足居民基本用水需求。首先,采用层次分析法(AHP)对影响水源地选取的关键因素进行分析,确定各因素权重;在此基础上对初步选取的应急水源地分区进行出口选址,并利用多指标模糊综合评价法对选址适宜性进行评价。结果表明,通过上述方法筛选出的3处应急水源地备选区显著提高了选址效率和适宜性,适合作为四川省特大城市的应急水源地。提出的方法克服了传统选址的主观性和低效率问题,显著提升了选址科学性和适宜性,对大型城市应急水源地选取具有重要参考价值,可有效保障城市在极端气候条件下的用水安全。
Frequent extreme climate events pose a threat to the water security of large cities.The purpose of this paper is to improve the efficiency and suitability of site selection,and ensure that the basic water needs of residents are met in emergency through improving the selection and evaluation methods of emergency water sources.Firstly,the Analytic Hierarchy Process(AHP)was used to analyze the key factors influencing the selection of water sources and determine the weights of these factors.Based on this,further site selection for emergency water source was conducted,and a multi-criteria fuzzy comprehensive evaluation method was used to assess the suitability of the selected sites.The results showed that the three candidate emergency water sources identified through this method significantly improve the efficiency and suitability of site selection,making them suitable as emergency water sources for large cities in Sichuan province.The proposed method overcomes the subjectivity and low efficiency of traditional site selection methods,significantly enhancing the scientific and suitability of site selection.It provides important reference value for selecting emergency water sources for large cities,effectively ensuring water security under extreme climate conditions.
