摘　　要： 城市生态安全评价指标体系结构功能分析是建立科学、和谐的评价指标体系的基础,可为我国建立生态城市理论研究和实践提供依据.在“环境指标P-S-R概念模型”基础上进行补充,在响应部分细分为观念意识响应和行动措施响应,构建4个层次的城市生态安全评价指标体系.第1层次是目标层,即生态安全评价综合指数;第2层次是项目层,由生态安全意识、生态安全政策、生态安全防控体系、社会状态、资源状态组成;第3层次是评价因素层;第4层次是指标层.建立评价指标体系以科学性、引领性、和谐性作为原则,采用AHP法,结合专家咨询,通过定性与定量控制确定项目层、因素层、指标层各指标的权重.以“意识—存在”互作为切入点,强调基于“观念”、“意识”,结合城市基础设施和生态环境进行城市生态安全评价,并对指标体系的结构和功能进行了分析. The structure analysis of the appraisal index system of the city ecology and its structure function is the foundation of setting up the scientific and harmonic evaluation index system which may provide the basis for the theoretical research and practice of establishment of ecological city and town. On the basis of the pressure-state-response（P-S-R） model of the environmental index the writer made the supplementary comments and submitted four city ecology safety appraisal index system. In accordance with consciousness response and action response the first category is the target that the comprehensive index of ecological security appraising index; the second category if the project scope that is formed by the ecological sense of security, ecological security policy, ecological security prevention and control system, social views and natural resources; The third category means evaluation factors and the fourth category is the index aspect. The principle for the appraisal index system is grounded on the scientific analysis, piloting and guiding and harmonic with AHP approach, integration of consultation from experts and technicians and the percentage of each category index from the project items, factors and various targets. The analysis should be conducted about the index system and structure function on the foundation of city ecology views about ＂existed consciousness＂ ,＂view points awareness＂ integration of city infrastructure and ecological safety.
