Correlation between Runoff Risk and Green Space Distribution——A Case Study of Jinshuihe Area in Zhengzhou City
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.
