海绵城市弹性基础设施的建设*--以台湾生态滞洪池为例

摘要

The core concept of "Sponge city" is using ecological techniques to create an urban "sponge" in order to cope with urban rainwater problems, and to improve the ability of cities to against and adapt to disasters. There are frequent floods in Taiwan. The detention basin, which is considered as a flexible strategy, is widely used in the prevention and control of waterlogging and storm water management. The paper has built case studies on the detention basins of Kaohsiung and Tainan, introduced the construction background, analyzed the city comprehensive planning, drainage and retention mechanism, construction method, operation and maintenance, and multifunctional benefits. The paper summarized the successful experiences of ecological detention basins in Taiwan, including the transition from grey to green infrastructure, multi-goal design and perfect non-structural measures, and to provide references for solving the problem of urban waterlogging in urban China by the applications of detention basins.%海绵城市的核心理念是提倡采用生态技术措施构建城市海绵体，从而解决城市的雨洪问题。台湾水患频发，生态滞洪池作为一种弹性策略被广泛运用到城市综合治水中。以台南、高雄生态滞洪池为例，介绍其建设概况，分析生态滞洪池的综合规划、排水滞洪机制、施工工法、运行维护等方面的特征以及其带来的生态效益、社会效益和经济效益。总结台湾生态滞洪池的工程实践，由“灰”向“绿”设施的转变、兼顾开发和生态的多目标设计以及完善的非工程措施等经验为我国城市新区建设和已建城区改造中进行雨洪管理提供借鉴。
