摘要: 通过Meta分析构建了张掖黑河湿地生态系统服务价值数据库和价值转移模型,对张掖黑河不同类型湿地价值进行有效评估,并对价值的影响因素进行综合分析,最后对模型的有效性进行检验。结果表明:(1)张掖黑河湿地生态系统服务总价值为19.41亿元,不同类型湿地价值由大到小依次为河流湿地(6.18亿元)、沼泽湿地(5.11亿元)、人工湿地(4.42亿元)、其他湿地(3.40亿元)和湖泊湿地(0.3亿元)。(2)Meta回归结果表明评估方法、湿地类型、生态系统服务类型、湿地面积是影响张掖黑河湿地生态系统服务价值变化的主要因素。(3)有效性检验结果表明,转移误差在可接受范围内,因此,将所构建的Meta分析价值转移模型应用于张掖黑河湿地生态系统服务价值评估是一种有效的方法。

Abstract: Through the Meta analysis, the service value database and value transfer model of Zhangye Heihe wetland ecosystem was constructed for the effective evaluation of the value of different types of wetlands in Heihe of Zhangye, and for the comprehensive analysis of the influencing factors of the value. The test on the validity of the model was then conducted. The results indicate that: (1) The service value of Zhangye Heihe wetland ecosystem is RMB 1.941 billion in total, and the value of different types of wetlands from large to small are river wetlands (RMB 618 million), swamp wetlands (RMB 511 million), artificial wetlands (RMB 442 million), other wetlands (RMB 340 million) and lake wetlands (RMB 30 million). (2) The meta regression results reveal that the main factors affecting the change of the service value of Zhangye Heihe wetland ecosystem include the assessment methods, wetland types, ecosystem service types, and wetland area. (3) The validity test results suggest that the transfer error is within the acceptable range. Therefore, applying the constructed meta analysis value transfer model to the evaluation of the service value of Zhangye Heihe wetland ecosystem is an effective method.
