Chinese and original region sponge city rainfall flood ecological management and control method and system based on LID measure and SWMM model

Abstract

The invention discloses a Chinese and original region sponge city rainfall flood ecological management and control method and system based on an LID measure and an SWMM model, and belongs to the technical field of city rainfall flood management. By optimizing an LID measure combination (permeable pavement + green roof + rainwater garden + grassed ditch) and a spatial configuration proportion thereof and combining with the SWMM model, hydrological and water quality benefits are quantified, and the ecological management and control of the sponge city rainfall flood in the Chinese and original region is realized. A multi-dimensional effectiveness evaluation system is introduced, the waterlogging reduction rate is 47.86%, the pollutant removal rate is 70-82.9% (P = 1a), the comprehensive score is 77.561, a standardized solution is provided for sponge city construction in the Chinese and original region, and the urban waterlogging prevention and control and non-point source pollution control capabilities are improved.
