本研究はメタ分析と標準化された土壌有機炭素モデルを用いて、熱帯の原生林と油ヤシ農園の炭素蓄積量を比較。油ヤシ農園は高炭素債務を抱え、原生林のバイオマスと深層土壌炭素の優位性が確認された。地域固有の保全と循環型管理の必要性を提言。
English
This study uses meta-analysis and a standardized SOC model to compare carbon stocks in tropical primary forests and oil palm plantations. Oil palm plantations incur high carbon debt, while primary forests maintain superior biomass and deep-soil carbon. Site-specific conservation and circular management are recommended.

📄 Abstract（原文）
Tropical rainforests are presently being cleared to large parts by humans. What is mostly characterized primarily by the transition of primary, old-growth forests into industrial oil palm plantations? This global shift severely disrupts carbon dynamics. Nevertheless, raising critical questions about its long-term impact on ecosystem carbon sequestration capacity. This study uses a meta-analytical approach and a standardized SOC vertical distribution model to evaluate and contrast total carbon stocks across aboveground biomass and variable soil depth profiles (0-30 cm and 0-70 cm) across three distinct tropical regions.The results show on a localized context, agronomic measures can sometimes result in a facade of recover on SOC on some localized field in a mid to later cycle, but also oil palm always suffer from a high carbon debt while comparing to pristine ecosystem. Overall primary forests remain in overwhelming structural superiority in terms of biomass and maintenance of deep-soil carbon for sustained periods. This should prompt establishment of site-specific conservation and circular management measures to reverse ecosystem degradation on a localized scale along with prevention of future destruction of remaining primary carbon sink.
