Quantifying ecosystem services as dependent on forest management and analyzing tradeoffs between them can help to make decisions on management more effective, efficient, sustainable, and stable. We use a forest management model (SILVA) to predict changes in ecosystem service provisions. Three stakeholder specific forest management scenarios (multifunctional, wood production, set-aside) for each of two different case study areas in Germany (a more and a less productive one) were simulated. We want to therewith answer how ecosystem service and biodiversity indicators (groundwater recharge, carbon sequestration, wood production, structural diversity of forest stands) depend on forest management and site. Forest management had significant influence on ecosystem service provisions in both case study areas. However, the results strongly depend on the site and on the initial situation in each location. In both case study areas, the production oriented forest management pays for productivity with structural diversity. In contrast, multifunctional oriented forest management pays for groundwater recharge with productivity losses. In the set-aside scenario, current carbon sequestration is high due to increasing forest carbon stocks, however sustainable carbon sequestration is low due to the lack of emission savings.

适应性森林管理的生态系统服务权衡

对依赖于森林管理的生态系统服务进行量化并分析它们之间的权衡关系,有助于做出更有效,高效,可持续和稳定的管理决策。我们使用森林管理模型(SILVA)来预测生态系统服务条款的变化。针对德国两个不同的案例研究区域(生产力水平较高和较低的区域)中的每个案例,模拟了三种特定于利益相关者的森林管理方案(多功能,木材生产,预留)。我们希望借此回答生态系统服务和生物多样性指标(地下水补给,固碳,木材生产,林分结构多样性)如何取决于森林管理和场所。在两个案例研究区域中,森林管理对生态系统服务的提供都产生了重大影响。然而,结果在很大程度上取决于站点和每个位置的初始情况。在这两个案例研究领域中,以生产为导向的森林管理都以结构多样性为生产力付出了代价。相比之下,多功能森林管理为地下水补给带来了生产力损失。在预留的情况下,由于森林碳储量的增加,当前的碳固存率很高​​,但是由于缺乏排放节省,可持续的碳固存率很低。
