生态功能分区是生态系统管理的重要环节,有助于维持生态可持续性.目前生态功能分区的框架复杂多样,但对多重生态系统服务之间关系的理解还不够深刻.生态系统服务簇可以识别多重生态系统服务间的交互作用,并依据簇的特征对区域进行生态功能分区,从而更好地进行社会-生态系统管理.本文以内蒙古自治区为例,定量评估了供给服务、调节服务和支持服务,以旗县(区)为基本空间单元,运用自组织特征映射网络(SOFM)得到生态系统服务簇、划分生态功能区.结果表明:研究区各项生态系统服务分布整体上呈现从东北向西南递减的格局;供给服务和调节服务存在权衡关系,支持服务和调节服务存在协同关系;依据聚类结果将内蒙古自治区划分为4个生态功能区,分别为西部荒漠生态脆弱区、中部草原水土保持区、东部草原牧业盈余区、东部森林生态均衡区.本研究基于生态系统服务簇的概念,分析了内蒙古自治区多重生态系统服务的权衡与协同关系,为生态功能分区提供了新的视角和方法.
Ecological function zoning is an tain the ecological sustainability. However, multiple and complicated, and the unders important part of ecosystem management and can main- the existent frameworks of ecological function zoning are tanding of the relationship between multiple ecosystem services is not deep enough. The ecosystem service bundles can identify the interaction among multi- ple ecosystem services and divide the region according to characteristics of the bundles, which can canT out the management of social-ecological system. In this paper, taking the Inner Mongolia Au- tonomous 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 eco- system service bundles at the county level, with the ecological function zoning on this basis. The re- suits 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 ecological balance area in eastern forest land. this paper analyzed the tradeoffs and synergies which provided a new perspective and method , livestock surplus area in eastern grassland, and Based on the concept of ecosystem service bundles, among multiple ecosystem services in the study area, for ecological function zoning.
