中文摘要：
文中在总结国内外城市生态安全评价模型、研究方法基础上，构建城市生态安全评价的表征模型一漏斗模型，并基于漏斗模型建立城市生态环境安全评价指标体系，运用主成分分析方法结合漏斗模型计算得到漏斗模型中压力度指数、支撑度指数、响应度指数并最终得出城市生态安全度指数。
英文摘要：
Based on the research of model and method inland and abroad, a model - Funnel Model using to describe the state of urban eco - security was developed in this research. An indicator evaluation system was set up based on Funnel Model, and the principal components analysis method was used to calculate the press degree index （PDI）, sustain degree index （SI）I） and response degree index （RDI）. Finally, with the comprehensive results of PDI, SDI and RDI related to Funnel Model, the urban ecological security degree index （ESDI） had been got.
