基于城市内涝防治的竖向规划体系探索--《郑州市竖向规划编制工作指引(试行)》解读

Vertical Planning System Based on Urban Flood Prevention and Control:Interpretation of the Guidelines for Vertical Planning Compilation in Zhengzhou(Trial Version)

随着全球气候变化加剧,作为影响城市防洪防涝安全的关键要素,城市竖向的重要性日益凸显。郑州市借助国土空间规划开展契机,深刻汲取“7·20”特大暴雨灾害教训,于2023年2月发布《郑州市竖向规划编制工作指引(试行)》(以下简称《工作指引》),构建了与国土空间规划体系相协调的“3个层级、5个类别”竖向规划编制体系,建立了因地制宜、刚弹相济的管控传导机制。结合郑州市发展特征和既有规划体系,《工作指引》梳理传统竖向规划的症结问题,明确各层级竖向规划内容和深度,从分层控制、统筹时空要素、规划协同、坚持安全底线、规划管理等层面探讨竖向规划编制方法和规划策略。《工作指引》将促进竖向规划的有效管理,推动郑州市国土空间规划体系完善,提升城市韧性承载能力。

As global climate change intensifies,the importance of vertical planning,a key element impacting urban flood prevention and drainage safety,has become increasingly prominent.Leveraging the territorial spatial planning,Zhengzhou took substantial lessons from the July 20,2021 torrential rainstorm and issued the Guidelines for Vertical Planning Compilation in Zhengzhou(Trial Version)(hereinafter referred to as the“Guidelines”)in February 2023.This document establishes a vertical planning compilation system with“three levels,five categories”that aligns with the territorial spatial planning system.It also introduces a management and control mechanism that is flexible and resilient and adaptive to local conditions.Based on the developmental characteristics of Zhengzhou and its existing planning system,the Guidelines identify critical issues in traditional vertical planning and clarify the scope and depth of vertical planning at each level.The Guidelines explore methods and strategies for vertical planning compilation from various perspectives,including layered control,coordination of spatial-temporal elements,planning coordination,maintenance of safety baselines,and planning management.The Guidelines will promote the effective management of vertical planning,advance the improvement of Zhengzhou's territorial spatial planning system,and enhance the city's resilience and bearing capacity.
