摘　　要：从城市内涝的致灾因子、承灾体暴露性和承灾体脆弱性属性出发,研究基于GIS的城市建筑内涝损失及风险定量计算方法.方法整合了来自内涝模拟淹水深度、建筑物空间分布以及其脆弱性属性多方面风险影响因素,对城市内涝风险进行定量评估.对北京左安东路片区的建筑内涝损失计算实例表明,该计算方法能建立单个建筑物尺度、具有空间分布属性的内涝损失和风险量化结果,为工程减灾和制定内涝管理对策提供基础依据.Based on disaster-inducing factors, exposure analysis and vulnerability analysis of urban local flooding, an approach of building content damage assessment and risk quantification methodology was demonstrated. The approach that realizing the integration of urban flooding model, building spatial distribution and vulnerability attributes, was adopted to carry out quantitative calculation of flood damage and risk. Through case study of Beijing Zuoan Road district, it is proved that this method is capable of exerting flood damage calculation and risk analysis with spatial properties at single building scale, thereby providing reference for formulating urban local flooding management and mitigation strategies.
