摘　　要：根据压力-状态-响应概念模型,从系统压力、系统状态和系统响应3个方面构建了4个层次的预警指标体系,并应用回归模型对许昌市的城市生态安全进行了预测和预警.结果表明:"八五"期间生态安全状况较差,"九五"、"十五"期间则有所改善,但总体状况不容乐观.According to the pressure-state-response model, the four-level warning indicator system is constructed from the system pressure, the system state and system response, which is used to forecast and warn the city eco-security by applicating regression models. The results show that： the whole eco-security situation was worse during “the 8th five-year plan”; the situation has improved during “the 9th five-year plan” and “the 10th five-year plan”, but the overall situation is not still optimistic.
