- 摘要:
- 通过“蓄排并举”提升城市防涝韧性是应对日益凸显的城镇内涝风险的重要手段。如何量化城市调蓄空间需求是落实蓄排平衡策略的首要问题。将三个国外城市规划中调蓄空间总量的计算方法与国内相关标准导则进行对比研究，分析这些方法在我国内涝防治韧性规划中的适用性。对比发现荷兰UWBM-SDF方法符合我国内涝防治标准中保证特定重现期下不发生内涝事件的要求，适合估算城市防涝韧性建设的长期总体调蓄目标。介绍了UWBM-SDF蓄排平衡曲线法在国内规划实践应用中的两个案例，提出了适合国内防涝韧性需求的城市调蓄空间量化方法的研究方向。
- Abstract:
- The combination of “storage & discharge” is an essential measure to handle the looming pluvial flood risks in Chinese cities. Therefore, how to quantify the required urban storage capacity becomes the priority for the implementation of “storage & discharge” strategy. This paper summarizes storage capacity calculation methods from urban planning of three countries, and compares them with the relevant Chinese standard and guidelines. The applicability of these methods is then assessed in the context of resilient pluvial flood protection planning.The result shows that the Dutch UWBM-SDF method aligns the principle in the Chinese standard of pluvial flooding prevention, which requires a city free of pluvial flood events under certain return period. UWBM-SDF can facilitate the quantification of long?term overall required storage capacity, and it has been applied in two Chinese case studies. In the end, the paper provides the future research direction towards the quantification method of storage capacity which fit the requirements of pluvial flood protection in Chinese cities.
