Ecosystem service (ES) is a growing field of research characterized by an increase in publication number. The review was conducted to provide an overview of trends of forest ecosystem services (FES) research and methodological approach to studied FES. Currently, the number of publications on ES was more than 18,000, but small publications were linked with FES. Based on the selection criteria, 41 peer-reviewed publications were screened to analyze the type of FES studied and the method used to quantify ES. The result showed that most of the research articles, to date, had focused largely on provisioning, regulating and cultural ecosystem services, which were timber production, water supply, carbon sequestration, and recreation. FES like a pollination, genetic resources, pest regulation, and aesthetic values have not been studied in any literature reviews. The review result showed that different studies used diverse methodological approaches and had inconsistent and scattered conclusions. From the selected studies, the majority of them were conducted in Europe and Asia. Particularly, the publication number from Ethiopia was very low and needs to conduct studies before the forest resources are further degraded.

全球森林生态系统服务研究趋势和方法论评估：荟萃分析

生态系统服务 (ES) 是一个不断发展的研究领域，其特点是出版物数量增加。进行审查的目的是概述森林生态系统服务 (FES) 研究的趋势和研究 FES 的方法论方法。目前，ES 上的出版物数量超过 18,000 篇，但小出版物与 FES 相关联。根据选择标准，筛选了 41 份同行评审的出版物，以分析所研究的 FES 类型和用于量化 ES 的方法。结果表明，迄今为止，大多数研究文章主要侧重于供应、调节和文化生态系统服务，即木材生产、供水、碳封存和娱乐。FES 就像授粉、遗传资源、害虫调控，和美学价值尚未在任何文献评论中进行研究。审查结果表明，不同的研究使用了不同的方法论方法，得出的结论不一致和分散。从选定的研究来看，其中大部分是在欧洲和亚洲进行的。尤其是埃塞俄比亚的出版物数量很少，需要在森林资源进一步退化之前进行研究。
