This paper simulated the runoff situation in the study area by combining ArcGIS with SCS-CN method and SWMM model,and analyzed the spatial relationship between runoff risk and green space dis-tribution through Moran coefficient analysis.The correlation between green space distribution and runoff risk was significant.The runoff risk and green space distribution in the study area exhibited a mismatch phenomenon based on runoff risk.Reasonable allocation and layout optimization of green space at the ur-ban scale could more efficiently solve the problem of urban waterlogging.
