摘要
城市内涝风险模拟与预警是指导城市减灾工作的重要依据。基于对国内外相关研究的梳理,发现在城市内涝风险模拟中技术模型需要从二维平面模型转换为三维空间模型,研究关注点需要从暴雨预报、灾损评估转化到内涝风险预警层面。在未来发展趋势中,要建立“多源数据-精准分析-动态预警”的研究体系,进一步针对研究区域的地域化特征,提取并叠加多种影响因子,融合城市地理、水文、气象、交通、规划等学科多源数据进行耦合分析,在多尺度系统中利用空间三维模型进行多情景内涝风险模拟,实现内涝风险动态预警,为韧性城市发展提供新思路。
Urban waterlogging risk simulation and early warning is an important basis for guiding urban disaster reduction.Based on the review of relevant research at home and abroad,it is found that the technical model in urban waterlogging risk simulation needs to be transformed from two-dimensional plane model to three-dimensional space model,and the research focus needs to be transformed from rainstorm forecast and disaster loss assessment to waterlogging risk early warning.In the future development trend,it is necessary to establish a research system of“multi-source data-precision analysis-dynamic warning”.Further,according to the regional characteristics of the study area,various influencing factors are extracted and superimposed,and multi-source data of urban geography,hydrology,meteorology,transportation,planning and other disciplines are integrated for coupling analysis.In the multi-scale system,the spatial three-dimensional model is used to simulate the multi-scenario waterlogging risk,realize the dynamic early warning of waterlogging risk,and provide new ideas for the development of resilient cities.
