The invention discloses a rainwater storage system for avoiding urban inland inundation, haze and heat island effects. A community is used as a unit, the rainwater storage system comprises an open-air greening system, a plurality of ecological filter pools, one or two landscape impounding reservoirs and ecological grass groove systems, wherein the open-air greening system is built on a roof of a building, the ecological filter pools are arranged on the periphery of the building, and the ecological grass groove systems are arranged near a community park, square and road. The rainwater storage system has the advantages that due to the fact that the greening system is arranged on the roof of the building, and a rainwater collection tank, the ecological filter pool, the ecological grass groove systems and the like are arranged on the ground, rainwater mainly infiltrates inwards and compensates for underwater, and the year-round rainfall runoff coefficient of a catchment area in the community is controlled within 0.12 to 0.15 and reaches the national park green space rainfall runoff coefficient design standard. The temperature difference is controlled within 1 DEG C to 3 DEG C, the urban community inland inundation, haze and heat island effects are thoroughly avoided, the landscape function is achieved, and the rainwater garden system is formed.
