- Abstract:
- Sponge city planning management control system in Wuhan was introduced, based on special design system, self-examination system and credit system. Through the combination of routine review and spot check review, the accuracy and efficiency of sponge city approvals are ensured. Through the collection of specific cases, the implementation effect, project design characteristics and overall investment intensity of sponge city construction are analyzed to evaluate the effectiveness of the planning management control system and the actual construction level. It was found that through the construction of sponge cities, urban non-point source pollution can be controlled at above 70.3%. Through the control of peak runoff coefficient, the bearing capacity of local rainwater pipe network can be improved from the existing recurrence period of one-year to the level of nearly two-year. The suitable investment range of the source sponge city construction project is 200-350 yuan/m2.
