摘　　要：水、能源、粮食是生态系统服务的重要组分,对供需平衡和区域高质量发展具有重要意义。利用InVEST模型、供需匹配度(SDMD)、Pearson相关性分析等方法量化2000—2020年天山北坡城市群产水、固碳、土壤保持和粮食生产4种生态系统服务的时空特征,探究不同尺度下供需匹配的空间异质性。结果表明:(1)研究区粮食生产服务供给总体呈上升趋势,产水、固碳与土壤保持服务供给则呈下降趋势。产水、固碳、土壤保持和粮食生产服务需求均呈上升趋势。(2)研究区产水和粮食生产服务供给呈西高东低,但需求与人口密集区重叠呈点状分布。固碳服务供给呈西南及中部高、东北部低,土壤保持服务供给与需求呈点状高值分布于天山山脉,供需空间分布大致相同。(3)土壤保持和粮食生产服务的SDMD上升,产水和固碳服务的SDMD呈下降。不同尺度下SDMD具有空间异质性,格网尺度下最为显著。(4)不同生态系统服务空间分异明显,分区控制-分类优化-分级治理是有效综合管控策略,可为天山北坡城市群经济社会高质量发展、生态环境保护和恢复提供科学支撑。Water,energy,and food are critical components of ecosystem services,influencing the supply-demand balance and high-quality regional development.Using the InVEST model,supply-demand matching degree(SDMD),Pearson correlation analysis,and other methods,this study quantifies the spatiotemporal characteristics of four ecosystem services(water production,carbon sequestration,soil conservation,and food provision)in the urban agglomeration on the northern slope of the Tianshan Mountains,Xinjiang,China from 2000 to 2020 and explores the spatial heterogeneity of supply-demand matching at different scales.The results indicate that:(1)The overall supply of food provision services in the study area exhibited an upward trend,whereas the supply of water production,carbon sequestration,and soil conservation services declined.The demand for all four services increased.(2)The supply of water production and food provision services was higher in the west and lower in the east,while demand was concentrated in densely populated areas in a point-like distribution.Carbon sequestration services had higher supply levels in the southwest and central regions and lower levels in the northeast.The supply and demand of soil conservation services formed a point-like high-value distribution in the Tianshan Mountains,with their spatial distribution roughly aligned.(3)The SDMD of soil conservation and food provision services increased,whereas the SDMD of water production and carbon sequestration services decreased.SDMD exhibited spatial heterogeneity across different scales,with the most significant variations observed at the grid scale.(4)The spatial differentiation of ecosystem services was evident,highlighting the need for zoning control,classification optimization,and hierarchical governance.These strategies can provide scientific support for highquality economic and social development,ecological protection,and the restoration of the urban agglomeration on the northern slope of the Tianshan Mountains.
