摘要
针对传统洪涝治理模式中市政排水和水利排涝分治的局限性,基于平原河网城市的地形特点和当前防洪排涝排水模式,提出了一种基于空间单元的多级雨洪管理方法.该方法以防洪、排涝、排水的重要通道为边界,划分不同等级的空间单元,对不同等级单元采取不同的工程治理手段,构建防洪-排涝-排水多级共治体系;并将该空间单元管理框架应用于宁波市海曙片进行多级共治工程布局,通过InfoWorks ICM模型验证工程效果.结果表明,基于空间单元的多级共治能理顺雨洪系统,耦合防洪、排涝、排水系统工程,为我国城市洪涝治理提供参考.
To address the limitation of traditional flood control method of managing municipal drainage and water conservancy drainage separately,this study proposes a spatial unit-based approach to rain and flood management that is tailored to the topographic features of river network in plain cities and the current flood control and drainage practices.This approach demarcates critical channels for flood control,urban flooding control,and drainage as boundaries,dividing different levels of spatial units,and employing distinct engineering methods for managing different levels of units,thus creating a multi-level co-governance system of“flood control-urban flooding control-drainage”.The spatial unit management framework is applied to Ningbo City,with its Haishu area serving as an example for the implementation of the proposed method.The engineering effectiveness is verified through the Infoworks ICM model.The results indicate that the multi-level collaborative governance based on spatial units can streamline the rainwater flood system,couple flood control,urban flooding control,and drainage system engineering,and provide a reference for urban flood management in China.
