Multi-objective forest planning methods were used to assess the trade-offs between three ecosystem services: timber production, erosion protection and biodiversity. The use of trade-off analysis helps to define proper weights for the management objectives and evaluate the feasibility of obtaining economic profit from timber while controlling the erosion risk and maintaining biodiversity ofAbies albaMill. Forests provide several ecosystem services (ES), many of which are in trade-off. The assessment of relationships between ES helps to optimize forest management. This study analyses the trade-offs between timber production, erosion protection and biodiversity in uneven-aged mountain forest of Abies alba Mill. Multi-functional forest management was optimized using a simulation-optimization software. Timber production was measured with present value, erosion risk was modelled as a function of stand structure, and biodiversity was dealt with by setting a minimum number of 10 large trees (dbh > 60cm) per hectare as a requirement. Optimizations were conducted for slopes of 10%, 45% and 80% and cutting cycles of 10, 30 and 50 years. Discount rate 2% was used in all optimizations. Trade-offs were evaluated with production possibility boundaries. We found relevant trade-offs between timber production and erosion protection, which depended on the slope steepness and the length of the cutting cycle. Trade-offs were marginal on 10% slope (50-year cycle) and large on 80% slope (10-year cycle). Biodiversity constraint reduced both economic profits and erosion protection values. In multifunctional mountain forest, defining proper weights for ecosystem services that are in trade-off is important for satisfying different management objectives in a sustainable way.

在管理年龄不均的冷杉阿尔巴磨坊时,经济盈利能力、减少侵蚀风险和生物多样性之间的权衡。站立
多目标森林规划方法被用于评估三种生态系统服务之间的权衡:木材生产、侵蚀保护和生物多样性。权衡分析的使用有助于为管理目标确定适当的权重,并评估从木材中获得经济利润的可行性,同时控制侵蚀风险并保持冷杉的生物多样性。森林提供多种生态系统服务 (ES),其中许多处于权衡之中。ES 之间关系的评估有助于优化森林管理。本研究分析了 Abies alba Mill 不均匀年龄的山地森林中木材生产、侵蚀保护和生物多样性之间的权衡。使用模拟优化软件优化了多功能森林管理。木材产量用现值衡量,侵蚀风险被建模为林分结构的函数,通过设定每公顷至少 10 棵大树(dbh > 60cm)作为要求来处理生物多样性。对 10%、45% 和 80% 的坡度和 10、30 和 50 年的切割周期进行了优化。在所有优化中使用了 2% 的折扣率。权衡与生产可能性边界进行了评估。我们发现了木材生产和侵蚀保护之间的相关权衡,这取决于坡度和切割周期的长度。在 10% 的斜率(50 年周期)和 80% 的斜率(10 年周期)上权衡取舍很小。生物多样性限制降低了经济利润和侵蚀保护价值。在多功能山林中,
