森林提供对人类至关重要的各种生态系统服务。随着气候变化，我们预计森林将发生重大变化，这将改变这些关键服务的供应，影响人类福祉。为了更好地了解气候变化对森林生态系统服务的影响，我们应用数据分析方法来评估佛罗里达天然火炬松（Pinustaeda L.）森林使用现场数据n = 16火炬松森林地块，包括输入，如立地指数，树木密度，年龄，降水量和温度为每个森林地块，我们评估了三个生态系统服务的相对地块水平的生产：木材，固碳和物种丰富度。结果表明，火炬松森林在佛罗里达在目前的气候条件下，这些生态系统服务的提供在很大程度上是低效的。气候变化对火炬松林提供生态系统服务的效率产生了较小的负面影响。在这种情况下，我们讨论了树木密度的减少，可能不会提高生态系统服务的生产。
Forests provide myriad ecosystem services that are vital to humanity. With climate change, we expect to see significant changes to forests that will alter the supply of these critical services and affect human well-being. To better understand the impacts of climate change on forest-based ecosystem services, we applied a data envelopment analysis method to assess plot-level efficiency in the provision of ecosystem services in Florida natural loblolly pine (Pinustaeda L.) forests. Using field data for n = 16 loblolly pine forest plots, including inputs such as site index, tree density, age, precipitation, and temperatures for each forest plot, we assessed the relative plot-level production of three ecosystem services: timber, carbon sequestered, and species richness. The results suggested that loblolly pine forests in Florida were largely inefficient in the provision of these ecosystem services under current climatic conditions. Climate change had a small negative impact on the loblolly pine forests efficiency in the provision of ecosystem services. In this context, we discussed the reduction of tree density that may not improve ecosystem services production.
