摘要

2005 - 2015年，葡萄牙大陆海松的森林面积减少了约10.6%，现有体积减少了约18.4%，主要原因是火灾和害虫(如线虫)在此期间发生。本研究的目的是研究葡萄牙森林中1立方米海松在此期间土地利用环境影响的演变，使用mil运河基于土壤有机碳测量的土壤有机质模型。结果表明，土地利用影响类别从2005年的16812 kg C亏缺增加到2015年的18423 kg C亏缺。土地改造为森林道路是土地利用影响的主要贡献，占总价值的54%，其次是土地占用为森林，约占40%。

Maritime pine land use environmental impact evolution in the context of life cycle assessment

Abstract Between 2005 and 2015, the forest area occupied by maritime pine trees in Continental Portugal decreased by about 10.6%, and the existing volume decreased by about 18.4% mainly due to fires and pests (e.g., nematode) that occurred during this period. The purpose of this study was to study the evolution of the land use environmental impact of 1 m3 of maritime pine, standing in Portuguese forest, during that period using the model by Milà i Canals based on soil organic matter measured by soil organic carbon. Results show that the land use impact category increased from 16,812 kg C deficit in 2005 to 18,423 kg C deficit in 2015. Land transformation to forest roads is the main contribution for land use impact representing 54% of the total value followed by land occupation as forest that represents about 40%.
