尽管发达国家有广泛记录，但对发展中国家如何以及是否发生森林转型的了解仍然有限。这项研究需要对哥斯达黎加西北部的土地覆盖转变趋势进行空间明确的遥感分析，以探索驱动所观察到的森林扩张的机制。我根据更广泛的保护和发展举措以及相关的经济趋势评估了主要转变模式的自然和社会经济景观环境，以便提出一个解释森林扩张的概念模型。结果表明，转化过程是相互关联的，并以独特的景观生态位为特征。低地地区出现了农业集约化，促进了高地地区边缘草地的重新造林。保护区的建立促进了森林恢复。然而，由于牛肉价格下降、农业集约化和林业政策修订，森林保护和再生对私有财产也具有重要意义。这项研究的内容为森林转型的经典解释提供了支持，同时强调了森林转型理论在解释观察到的重新造林趋势方面的局限性。
Though widely documented in developed countries, understanding of how and whether forest transitions occur in the developing world is limited. This research entails a spatially explicit, remote sensing based analysis of land cover conversion trends in northwest Costa Rica to explore the mechanisms driving the observed forest expansion. I assess the physical and socioeconomic landscape setting for dominant conversion patterns in light of broader conservation and development initiatives, along with relevant economic trends, in order to propose a conceptual model accounting for forest expansion. Results demonstrate that conversion processes are interrelated and characterized by unique landscape niches. Agricultural intensification occurred in lowland areas, facilitating reforestation of marginal grasslands in upland areas. Protected area establishment facilitated forest recovery. Yet forest conservation and regeneration were significant on private property as well due to the conjuncture of declining beef prices, agricultural intensification and revised forestry policies. Elements of this study provide support for aspects of the classic explanations for forest transitions while highlighting the limitations of forest transition theory to account for observed reforestation trends.
