【目的】探讨亚热带植被恢复过程中森林生态系统碳储量及其在各层次(植被层、枯落物层、土壤层)分配格局的变化,为揭示植被恢复对森林生态系统碳汇功能的影响机制和分阶段实施森林生态系统碳库管理措施提供科学依据。【方法】采用空间代替时间的方法,在湘中丘陵区选取地域毗邻、环境条件基本一致的檵木+南烛+杜鹃灌草丛(LVR) 、檵木+杉木+白栎灌木林(LCQ) 、马尾松+柯+檵木针阔混交林(PLL) 、柯+红淡比+青冈常绿阔叶林(LAG)作为一个恢复序列,设置固定样地,采用收获法建立部分主要树种相对生长方程和引用部分主要树种通用生长方程估算生物量,采集0~ 10、10~ 20、20~ 30和30~ 40 cm土层土壤样品,测...

Objective: The aims of this study were to investigate the change trends of carbon storage and its distribution pattern(vegetation, litter and soil layer) within forest ecosystems at different restoration stages in hilly area of central Hunan Province of China, in order to provide a scientific basis for explaining the influence mechanism of vegetation restoration on carbon sink function of forest ecosystem, and implementing forest ecosystem carbon reservoir management measures in stages. Method: By using the space-for-time substitution method, w...
