The present invention discloses a low elevation greenbelt rainwater regulation scheduling pool and a distributed rainwater regulation scheduling pool system. The distributed rainwater regulation scheduling pool system comprises a low elevation greenbelt (1), a rainwater overflow well (2) and a rainwater regulation scheduling pool (7), and water storage, drainage and supply which are integrated with a rainwater pipe network or a sewage pipe network are achieved. Compared with the prior art, rainfall runoff and flood detention can be effectively adjusted, runoff pollution can be reduced, and purification, storage and utilization functions of rainwater are fulfilled; and the system is tightly combined with the rainwater and sewage pipe networks of a city, the problems of urban inland inundation caused by rainstorm, the runoff pollution caused by rain wash, and rainwater resource utilization are solved, water storage is scheduled according to drainage ability of drainage pipelines, an important means is provided for sponge urban construction, and the system has outstanding social, environmental and economic benefits.
