摘　　要：利用天津市1961—2008年的气象观测资料,综合13个区县的自然、社会经济以及防灾减灾等数据,采用GIS和RS技术和自然灾害风险指数方法及洪涝灾害风险评价模型,得出天津市区县级洪涝灾害风险指数并绘制出风险区划图。结果表明:宁河大部、宝坻南部、武清东部、静海北部由于地势平坦、河网密集,其洪涝灾害风险的可能性最大;西青、东丽、津南、塘沽和大港的部分地区由于抗灾能力较强,孕灾环境敏感指数较小,洪涝灾害风险最小。According to Tianjin 1961-2008 meteorological data, integrating with natural, socio-economic and disaster prevention and reduction factors in 13 districts, using GIS and RS technology and natural disaster risk index method and flood risk assessment model, flood disaster risk index in county level was calculated in Tianjin. The results showed that： Ninghe most, Baodi south, Wuqing east, Jinghai north are most likely to be flood disaster risks because fiat dense river network, whereas Xiqing, Dongli, Jinnan, Tanggu and Dagang have least disaster environmentally sensitive index and floods risk due to powerful disaster-resistant.
