- Abstract:
- 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.
