摘要
针对我国海岸带"社会-经济-自然"复合生态系统,引用"驱动力-压力-状态-影响-响应力"分析模型,将生态安全中的驱动力、压力、状态和影响归为生态安全问题因素,作为响应力的作用对象。通过探讨响应力与生态安全问题因素的作用机制,建立定量评估体系分析海岸带生态安全响应力反馈效果、反馈效率和反馈充分性,并对厦门进行案例分析,希望能够对提升我国沿海城市的生态安全保障能力做出贡献。
The response of ecological security is the positive feedback of human to the ecological environmental problems. It is the force to maintain the ecosystem sustainable health, solve, mitigate or prevent the ecological security stress. Focus on the coastal social-economic-natural complex ecosystem in China, using ＂driving force-pressure-state-impact - response （DPSIR） ＂ model, the driving force, pressure, state and the impact were considered as ecological security problem factors （ESPFs） and the action targets of ecological security responses （ESRs）. By exploring the action mechanism between ESPFs and ESRs, a quantitative assessment method for coastal ESR＇s feedback effect, efficiency, and sufficiency was developed. Then, a case study in Xiamen was carried out. The stud- y will promote the coastal city＇ s capability of protecting the coastal ecological security.
