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 (Pinus taeda 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.
森林提供了对人类至关重要的众多生态系统服务。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并影响人类福祉。为了更好地理解气候变化对基于森林的生态系统服务的影响，我们应用数据包络分析方法来评估佛罗里达天然火炬松（Pinus taeda L.）森林中地块层面生态系统服务提供的效率。利用n = 16个火炬松森林地块的实地数据，包括每个森林地块的诸如立地指数、树木密度、年龄、降水量和温度等输入数据，我们评估了三种生态系统服务的相对地块层面产量：木材、碳固存和物种丰富度。结果表明，在当前气候条件下，佛罗里达的火炬松森林在提供这些生态系统服务方面大多效率低下。气候变化对火炬松森林提供生态系统服务的效率有轻微负面影响。在此背景下，我们讨论了树木密度的降低可能不会提高生态系统服务产量的情况。
