摘 要:随着城市化率的不断提高,城市雨洪灾害问题越来越严重以致成为全球城市水安全面临的挑战,雨洪基础设施对城市安全的重要性凸显。以城市水文学理论为基础,从城市化水文效应及城市雨洪基础设施对水文过程的替代角度,研究山地城市雨洪基础设施体系构成和特点,并以此分析城市内涝灾害的成因;基于灾害管理理论分析城市雨洪灾害构成,并从建设韧性城市角度提出山地城市雨洪管理策略,包括:管理目标、原则和方法。山地城市雨洪基础设施是一个等级有序的复杂系统,需要建立一套与之相适应的技术标准;将工程和非工程措施相结合可促进山地城市雨洪管理系统从防御性向韧性转变;加强系统智慧管理需要更多的定量模型研究。

Abstract: With the continuous increase of global urbanization rate, the problem of urban stormwater disaster has become more and more serious, which has become a challenge to global urban water security. The importance of stormwater infrastructure to urban resilience is therefore prominent. Based on the theory of urban hydrology and the hydrological effect of urbanization, the view of treating urban stormwater infrastructure as the substitution to the hydrological processes was used to analyze the composition and characteristics of the stormwater infrastructure system in mountainous cities, and it was also used to analyze the causes of urban waterlogging disasters.Based on the disaster management theory, the research analyzed the composition of urban stormwater disasters, and proposed stormwater management strategies for mountainous cities from the perspective of building resilient cities, including objectives, principles and methods of management. Stormwater infrastructure in mountainous cities is a complex system with an orderly hierarchy, and a set of technical standards needs to be established accordingly; the combination of engineering and non-engineering measures can promote the transformation of stormwater management systems in mountainous cities from defensiveness to resilience; Smart management of the system requires more quantitative model research.
