Meta分析方法及其在林学中的应用展望

Meta Analysis Method and Its Expectation in Forestry

Meta分析是一种以综合已有发现为目的,对单个研究结果进行综合分析的统计学分析方法。将Meta分析方法应用于林学,对林学的相关研究成果具有重要作用。基于文献资料搜集,从Meta分析的基本概念、优缺点、具体使用方法及其应用进行了概述,发现Meta分析在林学中多用在森林资源评价中,特别是森林生态系统服务价值的评估中,使用时要注意规避Meta分析方法的局限,弥补其他估算模型的不足,能够起到保护森林生态系统、维护林农的经济利益与完善森林生态补偿制度的作用。

Meta analysis is a statistical analysis method for comprehensive analysis of single research results with the purpose of synthesizing existing findings.The application of Meta analysis method to forestry plays an important role in the research and analysis of relevant research achievements of forestry.Therefore,based on the collection and reading of relevant literature and books,this paper had a certain understanding of Meta analysis.It also summarized the basic concepts,advantages and disadvantages,specific application methods and applications of Meta analysis.It was found that Meta analysis was mostly used in forest resource evaluation,especially in the evaluation of forest ecosystem service value in forestry.Attention should be paid to avoid the limitations of meta-analysis methods and make up for the deficiencies of other estimation models,which can protect forest ecosystem,safeguard the economic interests of forest farmers and improve the forest ecological compensation system.
