基于湿地生态系统健康理论和压力-状态-响应模型，以珠江口淇澳岛红树林湿地生态系统为研究对象，构建了红树林湿地生态系统健康评价指标体系，并确定了具体的评价指标、评价标准、指标权重、评价等级和评价方法，对珠江口淇澳岛红树林湿地生态系统健康状况进行了评价.结果表明：2008年，淇澳岛红树林湿地生态系统总健康指数为0.6580，评价等级为Ⅱ级（健康）；压力、状态和响应指标的健康指数分别为0.3469、0.8718和0.7554，说明该评价系统存在一定的压力，而状态和响应方面较好.作为省级自然保护区，珠江口淇澳岛红树林湿地生态系统健康水平有待进一步提升.红树林湿地生态系统健康评价研究目前尚不成熟，进一步研究需重点关注针对红树林特征的评价因子筛选、相关数据的长期定位监测、生态系统健康与生态系统功能的定量关系研究等.
Based on the theories of wetland ecosystem health and by using “Pressure-State-Response” model, a health assessment indicator system for Qi’ao Island mangrove wetland ecosystem in Pearl River Estuary was built, and the assessment indices, assessment criteria, indices weighted values, assessment grades, and assessment methods were established to assess the health state of this ecosystem. In 2008, the overall health index of this ecosystem was 0.6580, health level was of grade Ⅱ (healthy), and the pressure, state, and response indices were 0.3469, 0.8718, and 0.7754, respectively, suggesting that this ecosystem was good in state and response, but still had definite pressure. As a provincial nature reserve, this ecosystem was to be further improved in its health level. However, the research on the health assessment of mangrove wetland ecosystem was still young. Further studies should be made on the selection of assessment indices, long-term oriented monitoring of these indices, and quantification of the relations between ecosystem health level and ecosystem services.
