| 中文摘要: |
| 湿地生态系统与森林、海洋生态系统一起被称为地球三大生态系统，在维持地球生命和全球生态平衡方面起着不可替代的作用。对湿地生态系统健康进行评价，识别影响其健康的重要因子，为湿地健康的诊断和湿地保护与管理提供依据。以鄱阳湖国家湿地公园湿地生态系统为研究对象，在充分考虑湿地实际情况的基础上，从湿地自然环境、整体功能和社会环境3个子系统共选取21项评价指标，运用模糊综合评价法对湿地生态系统健康状况进行了综合分析。结果表明，鄱阳湖国家湿地公园生态系统健康度为0.619，处于第Ⅱ等级（健康）；3个子系统中，湿地的自然环境和整体功能分别在0.431和0.540的程度上属于较健康状态，湿地的社会环境健康状况最差，在0.452的程度上属于疾病状态；制约因素主要有土壤性状、物种多样性、物质生产功能、环保投资指数、化肥使用强度、农药使用强度以及人口自然增长率。从评价结果分析来看，湿地自然环境和整体功能受到的影响虽然没有社会环境受到的影响大，但也应引起足够的重视，这两类指标属于长期指标，在短时间不会产生巨大变化。 |

| The wetland ecosystem is one of the three major types of ecosystem, together with terrestrial and aquatic ecosystems, and plays a crucial role in the maintenance of life and the global ecological balance. Evaluating the health of a wetland ecosystem and identifying the important factors affecting health provides the basis for diagnosing ecosystem health and for protecting and managing wetlands. Poyang Lake National Wetland Park is the largest wetland park in China and contains a diversity of wetland landscapes and resources. Tourism in Poyang Lake National Wetland Park has developed to become the pillar of the local economy and the ecosystem is under intense pressure. In this study, a health assessment index for the wetland was developed. To consider all aspects of the wetland, 21 indices grouped in three sub-systems (wetland natural environment, social economic environment and overall function) were adopted and an evaluation method based on fuzzy logic was used to comprehensively evaluate wetland health. Results show that the wetland ecosystem of Poyang Lake Wetland Park is healthy (level II), with an ecosystem health index of 0.619. In terms of the three subsystems, the natural environment and the overall function of the wetland ecosystem were in a sub-healthy state, while the social environment of the wetland was unhealthy. The primary factors limiting wetland ecosystem health includes soil properties, species diversity, material production, environmental protection investment, chemical fertilizer use intensity, pesticide use intensity and population growth. Although the limiting factors affected the wetland natural environment and overall function less than the social environment, they must also receive attention because the natural environment and the overall function are long-term indicators and do not change markedly over the short term. |
