| Outline of Final Research Achievements |
This study valuated profitability of forest management according to logging systems and bucking strategies, by creating harvest schedules of plantation forests including non-clearcutting regime. The first strategy uses a traditional logging system with cable yarders yielding high-value logs; the second, efficient strategy uses vehicle-based forestry machines to mass-produce regular logs. The two strategies were compared at a regional scale. They yielded similar harvests, although the efficient strategy required fewer person-days and generates greater profits than the traditional strategy.

| Academic Significance and Societal Importance of the Research Achievements |
まず、様々な要因を考慮して林分レベルでの収益の差を明らかにした。次に、地域全体で持続的な木材生産をすることを前提とした収穫計画を策定し、地域レベルの収益性を評価すると共に、各森林に対して皆伐または非皆伐、皆伐の場合には伐期齢を割り当てた。これらの成果によって、林業事業体は経営方針が森林経営に与える影響を林分レベルだけでなく地域レベルでも把握することができ、より良い意思決定を行うための判断材料とすることが可能となる。
