【报告摘要】：
　　Important ecosystem services that underpin agricultural yields, such as pollination and biological control, are mediated by mobile organisms and depend on the availability of (semi-natural) habitats as well as their arrangement in the landscape. It has been suggested that coordinated or landscape-scale management of habitat in a multi-farm landscape results in higher provisioning of such ecosystem services compared to farm-scale management. However, to achieve optimal land-use under coordinated management it is necessary to define rules on how to use land to optimize aggregate benefits from ecosystem services. To this end, we aim to develop rules that characterize optimal solutions based on novel land-use pattern indices. To do this we model farmers' interdependencies through ecosystem services in an agent-based model (ABM) and optimize land-use patterns at both the individual farm and landscape scales for comparison. We demonstrate that the coordinated solution is characterized by a higher degree of habitat conservation generally and a configuration of habitat that is more dispersed rather than agglomerated. We test our rules characterizing optimal solutions on a range of assumptions about ecological parameter values and suggest that such rules could be used to improve governance of ecosystem services in agricultural landscapes.
