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.
基于湿地生态系统健康理论，运用“压力—状态—响应”模型，构建了珠江口淇澳岛红树林湿地生态系统健康评价指标体系，确立了评价指标、评价标准、指标权重值、评价等级及评价方法，对该生态系统的健康状况进行评价。2008年，该生态系统整体健康指数为0.6580，健康等级为Ⅱ级（健康），压力、状态和响应指数分别为0.3469、0.8718和0.7754，表明该生态系统状态和响应较好，但仍存在一定压力。作为省级自然保护区，该生态系统健康水平有待进一步提高。然而，红树林湿地生态系统健康评价研究尚处于起步阶段，应进一步开展评价指标筛选、指标长期定位监测以及生态系统健康水平与生态系统服务关系量化等方面的研究。
