中国海绵城市开发与加拿大综合雨洪管理对比研究:以多伦多为例

摘要

This paper introduces the progresses and evolution of stormwater management and planning in urban watersheds in Canada,as well as the wet weather flow management policies,principles,and standards in Toronto,the largest city in Canada.A comparison study has been conducted to provide new ideas and insights for stormwater management in China through comparing these policies,principles,and standards with the technical guideline for sponge city development in China.Some problems of the technical guideline have been pointed out,which include the lack of verification schemes for LID (low impact development) design,and the failure of consideration of precipitation.%介绍了加拿大城市流域雨洪规划管理的发展进程以及加拿大最大城市——多伦多市雨洪管理的政策、原则和标准,与中国的海绵城市建设技术指南进行对比,对指南中存在的一些问题,如指南未给出LID设计的检验和校核方案,也未充分考虑降雨等问题进行讨论,旨在为中国的雨洪管理提供新的研究思路和参考.
