Airport is quite difficult to use ＂conventional building or residential＂ mode in the con- struction of sponge city due to its restrictions from large hardened area, the area of terminal building and the surface material of the flight area. An airport in South China, located in the coastal area, is charac- terized by the low groundwater level, insufficient infiltration capacity of the soil as a reclamation area, and guarding against bird aggregation. At the same time, the airport was especially important for drainage and waterlogging, with high drainage grade and pressure. This article explored the two construction modes of an airport sponge city in the southern coast of China. On one hand, it implemented the sponge concept in specific planning and construction of the airport to alleviate the pressure of the airport drainage and waterlogging prevention, and to connect the drainage system in surrounding and upstream areas. On the other hand, it provided a design guide for the construction of sponge-like cities in special areas such as large-area-hardened flight areas and high runoff-contaminated apron areas. From source reduction, process control, to end governance, the whole process control of the airport water system was strength- ened, so as to establish a ＂large -medium -small＂ sponge system. The sponge system＇s technology can be further promoted in the similar airport in future.
