Summary:The utility model relates to a stepped rainwater garden system suitable for a mountain city, and belongs to the field of sponge city bioretention facilities. And the water diversion facility introduces the runoff gravity in the regulation and storage service range into the stepped regulation and storage system. The system is sequentially divided into a front decontamination pool, a stagnant flow purification pool and a waterlogging prevention regulation and storage pool from top to bottom. The front decontamination tank is used for removing high-concentration pollution in initial runoff, and the purification regulation and storage tank is used for controlling the runoff with sponge indexes and deeply purifying the runoff. The waterlogging-preventing storage pond is used for storing overproof high-recurrence-period rainstorm runoff, and the water supplementing pond is used for supplementing water for landscape plants during drought. The mountain city rainwater runoff control system can effectively solve the pr
