除了传统的木材生产外，其他森林功能，如生物多样性和娱乐，在过去几十年中也越来越重要。对森林的需求变得更加多样化，从而使森林管理和规划更加复杂。为了应对这些挑战，人们对更多样化的造林越来越感兴趣，为此有许多不同的管理选择。然而，各种管理备选办法如何影响可持续森林管理的经济、生态和社会方面仍不清楚。因此，在这项研究中，我们评估的后果，各种管理方案的不同方面的可持续森林管理，通过情景分析，使用林业决策支持系统。我们评估10个不同的森林管理方案，在瑞典的两个对比的城市，专家参与的方式基于网络的多标准决策分析框架的基础上。我们请森林经济、生态和社会价值专家以及驯鹿畜牧业专家对各自专业领域的若干指标进行权衡，并为每个指标建立价值函数。然后，我们确定了经济，生态和社会森林价值的不同权重集的情景排名。我们的研究结果表明，目前的管理实践是有利的经济方面（木材生产），而一些方案将更适合于实现瑞典共同平等的森林政策目标的生产和考虑环境问题，如方案具有较长的轮换期，更大的份额设置asides和更高的份额连续覆盖林业。这些措施不仅有利于生态价值，而且有利于社会价值和驯鹿畜牧业。此外，我们发现，专家通过网络工具参与是一种很有希望的替代办法，可以替代需要更多时间和资源投入的实际会议。
Besides traditional timber production, other forest functions, such as biodiversity and recreation, have gained increasing importance during the last few decades. Demands on forests have become more diversified, thus making forest management and planning more complex. To meet these challenges, there is a growing interest in a more diversified silviculture, for which a number of different management options are available. However, it remains unclear how the various management options affect economic, ecological, and social aspects of sustainable forest management. Hence, in this study, we assess the consequences of various management options on different aspects of sustainable forest management through scenario analysis using a forestry decision support system. We evaluate 10 different forest management scenarios for two contrasting municipalities in Sweden, based on expert participation by way of a web-based multi-criteria decision analysis framework. We asked experts in economic, ecological, and social forest values, as well as those in reindeer husbandry, to weigh a number of indicators in their field of expertise against each other, and to create value functions for each indicator. We then determined scenario ranking for different sets of weights for economic, ecological and social forest values. Our results indicate that current management practices are favorable for economic aspects (wood production), while a number of scenarios would be better suited to fulfill the Swedish co-equal forest policy goal of production and consideration of environmental issues, such as scenarios with longer rotation periods, a larger share of set-asides and a higher share of continuous cover forestry. These measures would be beneficial not only for ecological values, but also for social values and for reindeer husbandry. Furthermore, we found that expert participation through the web-tool was a promising alternative to physical meetings that require more commitment in terms of time and resources.
