摘　　要：引用"驱动力-压力-状态-影响-响应力"分析模型(driving-pressure-state-impac-response,DPSIR),具体分析了海岸带生态系统安全问题中"驱动力"、"压力"、"状态"、"影响"和"响应力"及其5者之间的相互关系,总结出人类社会对海岸带生态安全"响应力"的5个主要途径:法律法规与政策、管理体制与机制、基础建设与措施、科技支撑与投入、公众意识与参与。最后根据响应力对生态安全问题产生过程(驱动力、压力、状态、影响)的反馈机制,通过模糊数学评价原理构建出评估海岸带生态安全响应力的方法体系。The coastal ecosystem represents one of the typical ecotone, where the human activities are dense and frequent and ecological safety problems emerged gradually. The response to coastal ecological safety is the positive feedback of human society to the ecolog- ical safety problems. It is the force to keep the coastal ecosystem sustainable health and to solve, mitigate or prevent the ecological safety stress. This paper, the driving-pressure-state-impact-response （DPSIR） analysis model was introduced and to study the relationship among Response, Driving, Pressure, State and Impact. Subsequently, the human response was classified into 5 categories, which are policy and legislation, management institution and mechanism, infrastructure and project, science and technology support, public consciousness and participation. Finally, a primary evaluation method on response to coastal ecological safety was build up by using the fuzzy mathematic assessment principles, base on the relationship between response and other four ecological safety factors.
