Understanding resilience across the landscape: mapping, modeling, and managing ecosystem services

人类依赖于生态系统提供的服务，如食物、防洪和重建场所。试图最大限度地提供一种生态系统服务的管理可能会使生态系统容易受到其他生态系统服务下降的影响。出于这个原因，最近的研究呼吁更多地关注共同管理多个ES。然而，由于对ES之间的多重、非线性相互作用以及似乎调节这些相互作用的缓慢变化的变量的了解不足，这一点受到了阻碍。事实上，生态系统管理中的许多不确定性根源于对生态系统变化和提供多个生态系统之间的关系缺乏基本的、有经验的理解。我的研究计划的目标是通过研究两个生态系统(农业生产和水质)、它们的驱动因素(土地利用和管理)以及最终控制系统动态的缓慢变化变量(土壤磷浓度和持水量)的长期变化，来推进关于生态系统之间相互作用的理论。

Humanity depends on the services provided by ecosystems, such as food, flood control, and places to recreate. Management that attempts to maximize provision of one ecosystem service (ES) may make ecosystems vulnerable to declines in other ES. For this reason, recent studies have called for increased attention to co-managing multiple ES. However, this is impeded by an inadequate understanding of the multiple, non-linear interactions among ES and the slowly changing variables that appear to regulate these interactions. In fact, many uncertainties in ecosystem management are rooted in a lack of fundamental, empirically grounded understanding about the relationship between ecosystem change and the provision of multiple ES. The goal of my research program is to advance theory about the interactions among ES by studying long-term change in two ES (agricultural production and water quality), their drivers (land use and management), and the slowly changing variables that ultimately control system dynamics (soil P concentration and holding capacity).
