城市内涝防治体系韧性提升策略分析

Analysis of Strategies for Enhancing the Resilience of Urban Waterlogging Prevention and Control Management Systems

探究了内涝防治体系韧性内涵、韧性特征及韧性评估方法,从空间规划、工程建设和管理机制3个层面提出了内涝防治体系的韧性提升策略。以城市大排水系统为核心统筹规划,重视与城市防洪的关系,为超标降雨预留应急空间和末端出路。从源头、过程到末端全过程系统性提升城市排涝能力,重视基础设施的建设标准、相互适应性以及内涝防护设计。融合灾前预防、灾中抵抗、灾后恢复的管理体系和智慧化手段,提升灾害的适应性、可恢复性和智慧性。

The connotation,characteristics,and evaluation methods of the resilience of waterlogging prevention and control management systems were studied.A resilience enhancement strategy for waterlogging prevention and control management systems was proposed from three perspectives of spatial planning,engineering construction,and management mechanism.The overall planning takes urban drainage system as the core,emphasizes the relation with urban flood control,including provisions for emergency capacity and outlets for excessive rainfall.The urban flood drainage capacity is systematically improved throughout the entire process from source to end point by considering construction standards for system facilities,mutual adaptability,and waterlogging prevention design.Management systems and intelligent approaches for predisaster prevention,resistance during disasters,and recovery after disasters are integrated to enhance the adaptability,recoverability,and disaster intelligence.
