对多种生态系统服务的数量或供应水平的实际了解是加强当地生态稳定和保障人类福祉的关键先决条件。以泾河流域为例，研究了县域生态系统的粮食供给、肉类供给、水源涵养和土壤保持等4种生态系统服务功能。采用生态系统服务总量（TES）和生态系统服务价值权衡（TO）两个指标，研究了4种生态系统服务价值供给的空间差异。在此基础上，分析了影响空间差异的环境和土地利用因素。结果表明，该地区多种生态系统服务功能的供给存在较大的空间差异，其中TES和TO指数的空间差异分别高达6倍和12倍。降水量是制约多种生态系统服务总供给的主要因素。然而，环境因素对生态系统服务权衡的影响很小，虽然土地利用类型有显着的影响。草地面积的空间范围的增加，导致减少权衡和增强多种生态系统服务的供应。农田空间的增加产生了相反的效果。该案例研究为确定在何处以及如何增强多种生态系统服务提供了一个新的视角。
A practical knowledge of the amount or supply level of multiple ecosystem services is the key prerequisite for enhancing local ecological stability and securing the well-being of humanity. We studied the supplies of four ecosystem services: grain provisioning, meat provisioning, water conservation, and soil retention at the county level in the Jinghe watershed in northwestern China. The spatial differences of the supply of four ecosystem services were studied using two indices, the Total Ecosystem Services (TES) and Trade-Offs (TO) indices. Then, the environmental and land use factors affecting the spatial differences were also analyzed. The results show that large spatial differences exist in the supplies of multiple ecosystem services, in which the TES and TO indices varied by as much as six and 12 times from one area to another, respectively. Precipitation was the primary constraint on the total supply of multiple ecosystem services. However, environmental factors had little impact on the ecosystem service trade-offs, although the type of land use had significant impacts. An increase in the spatial extent of grassland area resulted in reduced trade-offs and enhanced the supply of multiple ecosystem services. A spatial increase in farmland had opposite effects. This case study provides a new perspective on identifying where and how to enhance multiple ecosystem services.
