生态系统管理的一个关键挑战是确定如何管理跨景观的多种生态系统服务。加强重要的供给生态系统服务，如粮食和木材，往往导致调节和文化生态系统服务，如营养循环，防洪和旅游业之间的权衡。我们开发了一个框架，分析跨景观提供多种生态系统服务，并提出了一个实证演示的生态系统服务束，一套服务，反复出现在一起。通过分析加拿大魁北克137个城市的混合使用景观中12种生态系统服务的空间格局，确定了生态系统服务束。我们确定了六种类型的生态系统服务束，并能够将这些束连接到具有不同社会生态动态的景观区域。我们的研究结果表明，供应和几乎所有的调节和文化的生态系统服务之间的权衡，他们表明，更大的多样性的生态系统服务是正相关的提供调节生态系统服务。生态系统服务束分析可以确定景观中生态系统管理产生了特别理想或不理想的生态系统服务的区域。
A key challenge of ecosystem management is determining how to manage multiple ecosystem services across landscapes. Enhancing important provisioning ecosystem services, such as food and timber, often leads to tradeoffs between regulating and cultural ecosystem services, such as nutrient cycling, flood protection, and tourism. We developed a framework for analyzing the provision of multiple ecosystem services across landscapes and present an empirical demonstration of ecosystem service bundles, sets of services that appear together repeatedly. Ecosystem service bundles were identified by analyzing the spatial patterns of 12 ecosystem services in a mixed-use landscape consisting of 137 municipalities in Quebec, Canada. We identified six types of ecosystem service bundles and were able to link these bundles to areas on the landscape characterized by distinct social-ecological dynamics. Our results show landscape-scale tradeoffs between provisioning and almost all regulating and cultural ecosystem services, and they show that a greater diversity of ecosystem services is positively correlated with the provision of regulating ecosystem services. Ecosystem service-bundle analysis can identify areas on a landscape where ecosystem management has produced exceptionally desirable or undesirable sets of ecosystem services.
