摘要:

为对庆阳子午岭森林生态系统服务价值进行评估,首先,通过效益转移法中的Meta分析法,建立Meta回归分析数据库;其次,构建回归模型进行效益转移评价,并检验模型的有效性。结果表明:1)庆阳子午岭森林生态系统服务价值的参考值为122.07亿元(2015年时的参考值),其中涵养水源、林木养分固持、保护生物多样性等服务功能对森林价值评估有显著影响;2)研究地所属区划、评估方法、生态系统服务类型等都是影响庆阳子午岭森林生态系统服务价值的因素,评估时要充分考量;3)使用误差检验法,其结果表明Meta回归模型得到的预测值和实际真实值之间一致性较高,可见,使用该模型评估森林生态系统服务价值有效。

Abstract:

As the largest part of the natural resource system on land,forest value assessment is very important for human development.Based on the Meta analysis method of benefit transfer,this paper established a Meta regression analysis database,constructed a regression model for benefit transfer evaluation,tested the effectiveness of the model and evaluated the forest ecosystem service value of Ziwuling in Qingyang.The results showed as follows:1)The reference value of forest ecosystem service value in Ziwuling was 12.207 billion yuan,in which forest nutrient retention,water conservation,biodiversity protection and other service functions had a significant impact on forest value assessment;2)Regionalization,assessment methods and ecosystem service types of the research area are all factors affecting the value of forest ecosystem services in Ziwuling,Qingyang,and should be fully considered in the assessment;3)The error test method was used in this paper,and the results showed that the predicted value obtained by the Meta regression model had a high consistency with the actual value,and the model was effective in assessing the value of forest ecosystem services.

Key words: Ziwuling forest, ecosystem service value, Meta-analysis, value assessment
