摘要： 由于城市的快速发展和土地利用覆被变化,由暴雨或台风引起的内涝已成为全球研究的热点。潜在的内涝风险危及建筑及室内财产安全。文章应用简化内涝模型模拟上海市中心城区不同情境下的积水情况,并根据每幢建筑室内进水深度对其进行暴露性分级。然后分析、评价了上海市中心城区建筑不同情境下的暴雨内涝灾害暴露性。研究结果发现:仓储和旧式住宅是最易暴露在内涝灾害中的建筑类型;总体上,杨浦、普陀和徐汇区是政府最需要采取安全措施的区域,长宁和虹口区处于中等暴露性水平;同时,内涝对黄浦、静安、卢湾和闸北区影响很小。研究结果可为地方政府改善内涝风险管理提供参考依据。

Abstract: Due to rapid urban development and land use and land cover changes, the waterlogging induced by torrential rain or typhoon in urban areas has been a global hotspot and a potential risk affecting the safety of urban buildings and interior property.This study applied a simplified urban waterlogging model to simulating the inundated water depth in central urban area of Shanghai under different scenarios.And each building was ranked according to its degree of exposure indicated by the inundation depth.Finally, the exposure of buildings to rainstorm waterlogging in central urban area of Shanghai under different scenarios was analyzed and evaluated.The results showed that the warehousing and the old-style residence are the most vulnerable building types when exposed to waterlogging disasters.On the whole, Yangpu District, Putuo District and Xuhui District are the important regions for the government to carry out safety defense, Changning District and Hongkou District have medium exposure rank, and the waterlogging brings little effects in Huangpu District, Jing’an District, Luwan District and Zhabei District.These results will provide references for the local government to improve waterlogging risk management.
