变化环境下城市暴雨洪涝研究进展

受气候变化和城市化进程的影响,近年城市暴雨洪涝问题频发、广发,暴雨难以精准预报、城市洪灾危害巨大,该问题受到高度重视和广泛关注,业已成为城市防洪减灾领域研究热点。本文以变化环境下的城市暴雨洪涝问题为研究对象,从城市暴雨洪涝模拟仿真、城市暴雨洪涝特征、城市暴雨洪涝形成机理以及城市暴雨洪涝应对管理4个方面对城市暴雨洪涝国内外研究进展进行综述。在此基础上,分析当前针对城市暴雨洪涝研究中存在的一些问题并对未来的研究进行展望,提出了以变化环境下暴雨洪涝特性和应对机制为重点的研究思路,以此,科学认识变化环境下城市暴雨洪涝,提升城市暴雨洪涝快速应对水平,最大限度降低城市暴雨洪涝灾害。

Research progress of urban storm flood under changing environment

The Urban Storm Flood (USF) has a higher frequency and is affected by global climate change and urbanization. The difficulty of rainstorm forecast and great harmfulness of urban flood disaster have been goten great attention and wide public concern, which makes it a research focus in the field of urban flood control and disaster reduction areas. Taking the USF under changing environment as research object, the paper reviewed the domestic and abroad research processes from four aspects such as simulation, characteristics, formation mechanism and response management.The paper pointed out some existing problems and prospected the future research,and proposed research idea which focuses on the characteristics and response mechanism of the USF under changing environment. This study should be beneficial to scientificly understand the USF and improve the rapid response ability to USF and reduce disaster loss of storm flood.
