中文摘要	在生态文明建设背景下的国土空间治理时代,国土空间生态修复是优化国土空间结构、提升国土空间功能的重要举措。针对西北生态脆弱区省域国土空间生态修复分区的理论创新与实践需求,该研究以县(区)为基本研究单元,将生态系统服务供需分析与国土空间生态修复分区结合起来,探索基于生态系统服务供需匹配程度差异的西北生态脆弱区省域国土空间生态修复分区思路与方法。对甘肃省的案例研究结果表明:1)除食物供给服务外,全省县域水源涵养服务、固碳释氧服务和土壤保持服务的总供给均大于总需求,但供给与需求存在明显的空间不匹配问题。2)甘肃省存在"高供高需""高供低需""低供高需"和"低供低需"4种供需匹配类型,但各项生态服务的主导供需匹配类型主要以"高供低需"和"低供低需"为主。3)依据区域生态系统服务供需差异及供需匹配类型,将甘肃省划分为绿洲保育、固碳提升、水源涵养和土壤保持4个生态修复大区,并按照自然地理特征与区域生态环境问题将4个大区划分为10个亚区,同时提出不同区域相应的生态保护修复工程措施。
英文摘要	In the era of land spatial consolidation under the background of ecological civilization construction, ecological restoration of territorial space is an important method to improve the ecosystem service function and optimize the spatial structure. According to the method and practice demand of the current ecological restoration of provincial territorial space in the ecological fragile areas of Northwest China, this paper took the county (district) as the basic research unit, combined the supply-demand analysis of ecosystem services with the ecological restoration of land space, used the modified ecosystem service value equivalent to quantify the supply of ecosystem services, and measured the total demand of ecosystem services based on the per capita demand of specified ecosystem services. Finally, this paper explored the method of provincial ecological restoration based on the difference of coupling index between supply and demand of ecosystem services. Gansu Province is an important water conservation area of the Yellow River and the Yangtze River, but it has been trapped with the problem of the mismatch between the supply and demand of ecosystem services for a long time, the human-environment contradiction is increasingly prominent, and the ecological environment problems such as soil erosion and vegetation destruction occur frequently. Based on the physical geographic environment and ecosystem characteristics of Gansu Province, the supply- demand analysis of food supply, carbon sequestration and oxygen release, water conservation and soil conservation services were conducted, and the spatial distribution traits were analyzed. Secondly, based on the supply-demand coupling status of four ecosystem services, the dominant mode of ecosystem services supply-demand coupling in each county (District) were identified. Thirdly, the paper identified the dominant restrictive factors and adjustability of the coupling mode of ecosystem services supply and demand, and then proposed the ecological protection and restoration and its leading direction according to the principle of "protecting ecological source areas and repairing damaged areas". The empirical result of case study in Gansu Province informs us that: 1) in addition to food supply services, the total supply of water conservation services, carbon sequestration and oxygen release services and soil conservation services in counties of Gansu Province is greater than the total demand, but there is a significant spatial mismatch between supply and demand. 2) There are four modes of supply-demand coupling condition in Gansu Province, which are "high supply and high demand", "low supply and high demand", "high supply and low demand", and "low supply and low demand", and the latter two are the dominant two modes. 3) According to the difference between the supply and demand of regional ecosystem services and the coupling mode of supply and demand, Gansu Province was divided into four ecological restoration regions: Oasis conservation, carbon sequestration, water conservation and soil conservation. Based on the physical geographical environment and regional ecological problems, the 4 regions were further divided into 12 sub regions, and corresponding ecological protection and restoration engineering suggestions were proposed.
