摘　　要：供水系统是城市的核心,在全球极端气候频发的大背景下,供水系统的脆弱性凸显。对于旅游城市而言,大规模流动人口的涌入对供水系统的冲击巨大,供水系统供需平衡矛盾突出。以三亚市为例,在充分分析城市供水特征的同时,引入流动当量人口概念,准确评价供水系统实际服务人口、旅游人口的现状生活用水水平,并提出针对实际服务人口、旅游高峰人口的韧性供水策略。在实际服务人口韧性供水方面,以实际服务人口为基数,通过构建多水源供水系统,提高供水水源系统的适应能力、恢复能力;通过增强供水设施能力,推进水厂互连互通,提高供水系统承受能力、适应能力,弹性应对用水需求。在旅游高峰人口韧性供水方面,通过适当扩大供水设施规模、预留供水设施用地、实施分质供水、精细化管理等措施,提高供水系统的恢复能力、适应能力、承受能力,缓解旅游高峰人口对供水系统的冲击。Water supply system is the core of a city.Under the background of frequent global extreme climate,the vulnerability of water supply system is an emerging challenge.For tourist cities,the influx of large-scale floating population has great impact on water supply system,and the contradiction between supply and demand of a water supply system is prominent.The water supply characteristics of Sanya were fully analyzed.In addition,the concept of floating equivalent population was introduced to accurately evaluate the current domestic water consumption level of the actual service population and the tourist population served by the water supply system,and a resilient water supply strategy for the actual service population and the tourist peak population was proposed.In terms of resilient water supply for the actual population,the adaptability and resilience of water supply source system were improved by constructing multi-source water supply system based on the actual population.Water demand was flexibly met by enhancing the capacity of water supply facilities,promoting the interconnection of water plants and improving the capacity and adaptability of water supply system.In terms of resilient water supply for the tourist peak population,the resilience,adaptability and capacity of water supply system was improved to alleviate the impact of the peak tourist population on water supply system by the measures such as appropriately expanding the scale of water supply facilities,reserving land for water supply facilities,implementing water supply with different quality and refined management.
