基于"水-能源-粮食"关系的生态系统服务供需匹配研究
Matching between supply and demand of ecosystem services based on the"water-energy-food"nexus:A case of the urban agglomeration on the northern slope of Tianshan Mountains
摘要
Abstract
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(SD-MD),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 ur-ban agglomeration on the northern slope of the Tianshan Mountains,Xinjiang,China from 2000 to 2020 and ex-plores 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 wa-ter production,carbon sequestration,and soil conservation services declined.The demand for all four services in-creased.(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 sup-ply and demand of soil conservation services formed a point-like high-value distribution in the Tianshan Moun-tains,with their spatial distribution roughly aligned.(3)The SDMD of soil conservation and food provision ser-vices increased,whereas the SDMD of water production and carbon sequestration services decreased.SDMD ex-hibited 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 high-quality economic and social development,ecological protection,and the restoration of the urban agglomeration on the northern slope of the Tianshan Mountains.关键词
