本研究は、チリ南部のロブレ・ラウリ・コイグエ混合林および常緑林における経済的収益性と炭素吸収を評価。フォーストマンモデルと動的計画法を用いて、最適伐採周期と土地期待値を算出。混合林は単一樹種林より収益性が高く、炭素価値を組み込むと土地期待値が上昇し、気候変動緩和と森林所有者の収入多様化に貢献。
English
This study evaluates the financial profitability and carbon sequestration of mixed native forests in southern Chile using the Faustmann model. Optimal rotation periods are determined for timber-only and combined timber-carbon scenarios. Mixed forests outperform monocultures, and including carbon value increases land expectation value, supporting climate mitigation and income diversification.

📄 Abstract（原文）
This study evaluates the financial profitability and carbon sequestration in mixed native forests of the Roble-Raulí-Coigüe and evergreen types in the southern macrozone of Chile, integrating both ecosystem services into forest management decision-making. The Faustmann model and dynamic programming were applied to determine the optimal rotation periods and Land Expectation Value (LEV) under two scenarios: exclusive timber production and combined timber and carbon production. The results indicate that mixed forests consistently outperform monocultures in terms of profitability, especially in 25%–75% mix configurations and moderate densities (2000 trees/ha). The observed range of 25%–75% across different tree species is determined by the interplay of two critical factors: the average annual growth rate (AAGR) of biomass and the opportunity cost of the forest rotation. In fast-growing species, the upper limit (75%) reflects an optimisation towards early carbon sequestration, whilst in slow-growing species, the ratio shifts towards the lower limit (25%) to compensate for longer rotation periods and associated biotic risks. This range acts as an efficiency frontier that balances biological productivity with the stability of the accumulated carbon stock. The inclusion of the economic value of carbon increased the LEV and extended the optimal rotation periods, confirming the relevance of integrating ecosystem services into forest planning. These findings suggest that mixed native forests represent a competitive and sustainable alternative to monocultures, contributing to climate change mitigation and income diversification for forest owners.
