Under the background of intensified global climate change, seasonal flood disasters and increasing water consumption are two major challenges to the development of scenic spots. In order to address the conflict between frequent flood disasters and water scarcity, and to mitigate the adverse impacts of climate change, this paper explores strategies of stormwater management in scenic areas. Taking Yesanpo Scenic Area as an example, based on topographic data and hydrometeorological data, this paper uses the SCS-CN model and ArcGIS to simulate the inundation area caused by the design rainfall depth of 2% rainfall frequency in the study area. On this basis, according to the volume capture ratio of the annual rainfall of 85%, green stormwater infrastructure is planned, improving the scenic area’s ability to resist floods that occur once in fifty years and make use of stormwater resources to achieve safe, healthy, and sustainable development.
