Abstract: Ecological function zoning is an important part of ecosystem management and can maintain the ecological sustainability. However, the existent frameworks of ecological function zoning are multiple and complicated, and the understanding of the relationship between multiple ecosystem services is not deep enough. The ecosystem service bundles can identify the interaction among multiple ecosystem services and divide the region according to characteristics of the bundles, which can carry out the management of social-ecological system. In this paper, taking the Inner Mongolia Autonomous Region as an example, we quantitatively evaluated the provisioning service, regulating service and supporting service, and used the self-organization feature map (SOFM) to get the ecosystem service bundles at the county level,with the ecological function zoning on this basis. The results showed that the distribution of ecosystem services appeared a decreasing trend from northeast to southwest. There were tradeoffs between provisioning and regulating services, and synergies between supporting and regulating services. According to the bundles results, we divided the Inner Mongolia Autonomous Region into 4 ecological function zones: ecological fragile area in western desert, soil and water conservation area in central grassland, livestock surplus area in eastern grassland, and ecological balance area in eastern forest land. Based on the concept of ecosystem service bundles, this paper analyzed the tradeoffs and synergies among multiple ecosystem services in the study area, which provided a new perspective and method for ecological function zoning.
