摘　　要：[目的]研究鄱阳湖生态恢复工程对湿地生态系统健康的影响。[方法]以PSR概念模型为基础,构建了包含3个子系统22个指标的鄱阳湖湿地生态系统健康评价指标体系和综合评价模型,对1990、1996、2002、2006和2012年鄱阳湖湿地生态系统健康状况进行评价。[结果]1990、1996、2002、2006和2012年鄱阳湖湿地生态系统分别处于轻微病态、轻微病态、亚健康、亚健康、亚健康状态。这说明鄱阳湖生态恢复工程成效比较显著,湿地管理水平和机构设置能力有所提升。[结论]该研究为鄱阳湖湿地的管理和生态修复提供了科学依据。[ Objective ] The study aims to discuss the effects of ecological restoration projects in Poyang Lake on the wetland ecosystem. [ Method] Based on the Pressure-State-Response （PSR） conceptual model, a health assessment indicator system of wetland ecosystem in Poyang Lake （consisting of 22 indicators grouped into pressure, state and response subsystems ） and the comprehensive evaluation model were constructed, and health states of the wetland system in 1990, 1996, 2002, 2006, and 2012 were finally assessed. [ Result] The wetland sys- tem in Poyang Lake was slightly morbid in 1990 and 1996, and then it was sub-healthy in 2002, 2006, and 2012. It shows that the ecological restoration projects in Poyang Lake were effective, and the level of wetland management and institution setting ability in Poyang Lake have improved. [ Conclusion ] The research provides scientific references for the management and ecological restoration of wetland in Poyang Lake.
