This study presents a meta-analysis of the economic values of global forest ecosystem services. The meta-analysis is conducted based on data from primary studies published between 1990 and 2018. The value-estimates from those studies are standardized into international currency units i.e. US dollar/ha/year using the purchasing power parity of countries at 2017 price levels. This standardization results in a database of 261 eligible primary studies and 758 value-estimates or observations. The study reveals large variations in the reported economic values of forests and the ecosystem services that they provide. Results from the meta-regression indicate a range of drivers that influence these economic values, including GDP per-capita, proportion of forest cover, continental location, type of forest, ecological zone, forest area, ecosystem services being valued and the valuation method employed. The meta-regression results also indicate the importance of valuing multiple ecosystem services together, rather than valuing specific services separately. The danger with the latter approach is that valuation studies can inadvertently suggest industrial plantation forests, with harvesting for timber or bio-mass energy, have the greatest economic value. However, such studies do not properly consider trade-offs inherent in the management of these types of forests; namely the loss of multiple ecosystem services that are provided by more natural forests. These findings contribute to the literature evaluating the economic values of global forest ecosystem services by conveying relevant information regarding the divergence of the economic values associated with different forest features, thus helping to inform forest management.

全球森林生态系统服务的经济价值:荟萃分析

本研究对全球森林生态系统服务的经济价值进行了元分析。元分析是基于 1990 年至 2018 年间发表的主要研究数据进行的。这些研究的价值估计被标准化为国际货币单位,即美元/公顷/年,使用各国 2017 年价格水平的购买力平价。这种标准化产生了一个包含 261 项符合条件的初级研究和 758 项价值估计或观察的数据库。该研究揭示了所报告的森林经济价值及其提供的生态系统服务的巨大差异。元回归的结果表明影响这些经济价值的一系列驱动因素,包括人均 GDP、森林覆盖率、大陆位置、森林类型、生态区、森林面积、被估值的生态系统服务和采用的估值方法。元回归结果还表明将多个生态系统服务一起评估而不是单独评估特定服务的重要性。后一种方法的危险在于,估价研究可能会无意中表明,以木材或生物质能源为目的的工业人工林具有最大的经济价值。然而,此类研究并未适当考虑这些类型森林管理中固有的权衡;即更多天然森林提供的多种生态系统服务的丧失。
