摘　　要：首先论述了目前国内外关于城市地震灾害风险评估的研究，分析了这些研究取得的成果和存在的不足．然后，提出了城市防震减灾能力的概念，采用人员伤亡、经济损失和震后恢复时间作为衡量城市防震减灾能力强弱的３个最基本的要素．围绕这３个基本要素，列举出影响城市防震减灾能力的６大因素，在此基础上，提出了城市防震减灾能力评价指标体系的具体内容．In this paper, the current studies and practices on earthquake disaster risk analyses for ur- ban area are reviewed and the achievements and weaknesses are pointed out. For assessing the city's safety to the earthquake disasters, the conception of city's ability for earthquake disaster re- duction is presented. The ability could be evaluated with three basic elements - the possible seis- mic casualty and economic loss during the future earthquakes that are likely to occur in the city and its surroundings and time required for recovery after earthquake. Based upon these three basic ele- ments, a framework, which consists of six main components, for evaluating city's ability reducing earthquake disasters is proposed.
