近些年我国城市内涝问题频发，其中有城市快速扩张、排水系统老化等表面上的原因，更主要的是在集中收集、快排为主的雨水排放指导思想下，应对超过管道排水能力的雨水问题时捉襟见肘，而“海绵城市建设”的提出给解决内涝问题提供了新的思路和方法。通过分析内涝产生的原因及可能的应对手段，结合我国古代城市内涝管理及国外城市建设的经验，提出应把排水与蓄滞结合起来统一考虑，合理规划城市排水管网、城市河湖水系、城市绿地三个要素的布局，绿地的低影响开发结合管道排水系统应对普通降雨，以提高河网等地表排水通道密度，结合地下大型排放设施、地面安全洪泛区和天然水体等调蓄设施应对超量雨水，是防止城市内涝的有效解决方法。%In recent years, the problem of waterlogging frequently happened in most cities of China, including the obvious reasons such as rapid expansion of cities and the aging problems of the drainage system. More importantly, the guiding ideology of drainage is the concentration of rainwater colection and fast row can’t in responding to the storm water more than the capacity of drainage pipeline. Raising the "Sponge City" provides new idea and methods to solve the problem of waterlogging. By analyzing waterlogging generated reasons and possible treatments, learn ancient China on the management of urban waterlogging and foreign experience in the city construction. Proposed that waterlogging issue should be considered with the drainage and store, rational planning of urban drainage pipe network, and developing urban lake water systems and urban green spaces. With low impact development of green space with pipe drainage systems to deal with ordinary rainfal, by improving the river surface drainage channel density, combined with the storage facilities such as large underground drainage facilities, security lfooding area and natural water to deal with excessive rainfal is an effective solution to prevent waterlogging in the city.
