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
