摘要: 为了对吉林省西部自然保护区湿地生态效益及生态恢复情况进行科学评价,基于生态系统服务价值理论和突变理论构建湿地生态效益评价指标体系,结合生态效益的多元性特征,应用层次分析法和熵值法等多目标规划与决策方法,参照研究区2001年的生态效益研究成果,对其2005和2012年现状生态效益及其生态恢复情况进行评价.结果显示: 2005年以来莫莫格保护区的湿地生态效益水平很高,查干湖、向海保护区湿地生态效益处于较高水平,大布苏保护区湿地生态效益水平一般.突变级数法、层次分析法、熵值法等多目标规划与决策方法结合应用,能够科学地体现湿地生态效益的动态性和整体性,准确地反映研究区生态恢复的客观实际情况;近年来吉林省西部自然保护区的生态保护与环境治理工作初见成效,主要保护区的湿地生态系统对人为增益性干扰积极响应,湿地整体效益得到恢复和提高.

Abstract: In order to correctly evaluate wetland ecological benefit and restoration in the natural reserves of western Jilin Province, an index system of wetland ecological benefit assessment for nature reserves was established based on ecosystem service theory and catastrophe theory. Considering the diversity characteristics of ecological benefit, and consulting the research results of ecological benefit in study area in 2001, the analytic hierarchy process and entropy method were introduced to analyze the ecological benefit and restoration in 2005 and 2012. The results showed that the ecological benefit level was very high in Momoge Nature Reserve since 2005, high in Chaganhu and Xianghai nature reserves, and moderate in Dabusu Nature Reserve. This study showed that the assessment combining the catastrophe progression method with the analytic hierarchy process and entropy method could reveal the dynamics and the integrality of wetland ecological benefit, and accurately reflect the reality of the ecological restoration in study area. In recent years, some achievements in ecological protection and environmental remediation had been obtained in the west of Jilin Province, and the whole ecological benefit of the wetlands had been improved and enhanced by means of man-made effective interference.
