中国城市规划设计研究院水务与工程院副院长、教授级高级工程师谢映霞认为,在海绵城市离不开合理规划,城市总体规划要解决哪些区域不能开发建设的问题,还要解决在允许开发建设的区域内需要控制多少雨水径流量、哪些地方应建设低影响开发雨水系统、为这些设施预留多少用地空间等问题。因此,各地要因地制宜确定年径流总量控制率及其对应的设计降雨量,将这个指标作为控制目标,并制定城市低影响开发雨水系统的规划原则和实施策略,确定重点实施区域,优化土地利用布局。 Xie Yingxia, associate dean of China Academy of Urban Planning and Design and a professor-level senior engineer, believes that sponge city can not do without proper planning and urban master plan to solve the problem of what areas can not be developed and construction, How much stormwater runoff needs to be controlled in the region and where there should be issues of low impact on the development of rainwater systems and how much land space is reserved for these facilities. Therefore, all localities should determine the total amount of annual runoff control rate and its corresponding design rainfall, this indicator as a control target, and development of urban low impact on the development of rainwater system planning principles and implementation strategies to determine the key implementation of the region to optimize land use layout.
