基于PSR模型建立了深圳湾福田红树林保护区生态系统健康评价体系，运用层次分析法对保护区健康状况进行评价。结果表明：保护区生态系统的压力、状态、响应在体系中的比例分别为53.89%、29.73%、16.38%，健康指数分别为0.4080、0.5891、0.6037；保护区综合健康指数为0.4939，处于健康等级Ⅲ级(亚健康状态)。造成以上结果的主要原因为：①近30年来城市化发展导致保护区生态系统丧失部分生态功能，健康水平不断下降；②水污染、人工引种植物和病虫害等对保护区造成巨大外界压力；③建筑施工和人类活动影响保护区自然状态的恢复。

An ecosystem health assessment system of Futian Mangrove Nature Reserve in Shenzhen Bay was developed based on PSR model and the AHP method was used to assess health state of the reserve. The results showed that the proportion of pressure, state, and response of the ecosystem in the system were 53.89%, 29.73% and 16.38% respectively, and their health index were 0.4080, 0.5891, and 0.6037 separately. The comprehensive health index of the whole ecosystem was 0.4939, indicating a health level of III (sub-healthy state) of the reserve. The main causes for that include:1) urbanization in recent 30 year has resulted in losses of some ecological functions of the ecosystem and continual decline of ecosystem health. 2) Water pollution, artiifcial introduction of alien plants, and pests and diseases have imposed tremendous external pressures on the reserve. 3) Construction and human activities have partly inlfuenced the restoration of the ecosystem.
