Agri-environmental measures differ in their capacity to simultaneously enhance the provision of multiple ecosystem services. Multifunctional approaches are hampered by funding schemes that are usually administered by individual administrative sectors that each predominantly focus on one single environmental objective. Developing integrative management strategies that exploit synergies from implementing multifunctional measures is challenged by the need to quantify expected management effects on different ecosystem services. The objective of this paper is to compare uncoordinated versus coordinated management strategies in their contribution to multiple environmental objectives. We developed and applied a method for quantifying effectiveness, as well as spatial and cost efficiency with respect to four key landscape functions: erosion prevention, water quality conservation, climate change mitigation and safeguarding biodiversity. The case study area was the county of Verden, Germany. The following findings can be drawn: Measures for safeguarding biodiversity and climate change mitigation have generally high multifunctional effects, which makes them suitable for integrative management strategies. To make use of the added value of potential multifunctional measures, a spatially targeted allocation of agri-environmental measures is necessary. Compared to uncoordinated strategies, coordinated integrative management strategies either allow the optimization of the ratio of costs to environmental effects or an increase in the effects that can be achieved within an area unit. This is however, usually not simultaneous. Future research should seek to refine the assessment and valuation indicators.
农业环境措施在同时增强多种生态系统服务的能力方面存在差异。多功能方法受到资金计划的阻碍，这些资金计划通常由单个行政部门管理，每个部门主要侧重于一个单一的环境目标。开发利用多功能措施协同增效的综合管理策略，需要量化对不同生态系统服务的预期管理效果，这面临着挑战。本文的目的是比较不协调与协调管理策略对多个环境目标的贡献。我们开发并应用了一种方法，用于量化有效性，以及与四项关键景观功能（防止侵蚀、保护水质、减缓气候变化和保护生物多样性）相关的空间和成本效率。案例研究区域是德国的维登县。可以得出以下结论：保护生物多样性和减缓气候变化的措施通常具有很高的多功能效应，这使得它们适合综合管理策略。为了利用潜在多功能措施的附加值，需要对农业环境措施进行有针对性的空间分配。与不协调的策略相比，协调的综合管理策略可以优化成本与环境效果的比例，或者在单位面积内提高可以实现的效果。然而，这通常不是同时的。未来的研究应寻求改进评估和估值指标。
