Through the construction of an ecological lawn regulation and storage system, the adaptability of airports to extreme weather can be enhanced. The problems of runoff, ponding and pollution faced by traditional airport flight areas during heavy rainfall can be solved, and the utilization efficiency of rainwater resources can be improved. In this paper, the SWMM is used to simulate and analyze an 4E-level airport of a certain city in Region III as the research object. The simulation results show that the ecological lawn regulation and storage system can significantly reduce runoff flow, ponding durations and runoff pollution with different return periods. In addition, the water storage module of the system can store 24,000 m3 of water and recycle it. This research proves that the ecological lawn regulation and storage system can effectively improve the rainwater control capability of the airport flight area, which has an important reference value for the sponge transformation of traditional airports and is helpful to promote green civil aviation construction and sustainable development.
