摘要: 干旱区生态系统服务供需平衡对区域可持续发展至关重要。本研究以新疆为研究区域,从生态系统服务的供给和需求视角出发,采用双变量空间自相关方法,分析2000—2020年粮食生产、生境质量、碳储存、土壤保持、产水量和绿地休闲的供给和需求与人类活动强度的时空关联特征。结果表明: 2000—2020年,研究区6种生态系统服务处于供给远大于需求的状态(供需比>1),研究区单位面积产水量、碳储存和土壤保持的供给分别增加28.61 m3·km-2、18.24 t·km-2和3147 t·km-2,单位面积需求分别增加14.2 m3·km-2、59.85 t·km-2和7151.52 t·km-2,粮食生产、绿地休闲和生境质量供给和需求变化不显著;粮食生产和产水量供需比分别增长118.2%和34.9%,而碳储存、土壤保持的供需比分别下降83.7%、108.9%和20.9%,生境质量和绿地休闲的供需比变化不显著。研究期间,98%的区域的人类活动强度指数(HAI)在0.25以下;空间上呈现出以天山为界北高南低、零星分布的格局。粮食生产、产水量和生境质量的供需比与HAI整体呈显著负相关关系,而碳储存、土壤保持和绿地休闲的供需比与HAI则呈显著正相关。粮食生产、碳储存、生境质量和绿地休闲的供需比与HAI在天山北坡城市带和塔里木河流域绿洲区以低-高集聚为主,而土壤保持和产水量的供需比与HAI在天山山脉和环塔里木河流域以高-高集聚为主。

Abstract: The balance between supply and demand of ecosystem services in arid zones is crucial for regional sustainable development. Taking Xinjiang as the study area, we analyzed the spatial and temporal variations of the supply and demand of food production, habitat quality, carbon storage, soil conservation, water yield and greenfield leisure in relation to the intensity of human activities during 2000-2020 by using bivariate spatial autocorrelation method. The results showed that from 2000 to 2020, the six ecosystem services in the study area were in a state where their supply was far greater than demand (supply/demand ratio>1). The supply of water yield, carbon sto-rage and soil conservation per unit area increased by 28.61 m3·km-2, 18.24 t·km-2 and 3147 t·km-2, respectively. The demand increased by 14.2 m3·km-2, 59.85 t·km-2, and 7151.52 t·km-2, with insignificant changes in supply and demand for food production, greenfield leisure, and habitat quality. The supply-demand ratios for food production and water yield increased by 118.2% and 34.9%, respectively. Carbon storage and soil conservation decreased by 83.7%, 108.9%, and 20.9%, respectively. The supply and demand ratios of habitat quality and greenfield leisure did not change significantly. From 2000 to 2020, human activity intensity index (HAI) in 98% of the study area were below 0.25. Spatially, HAI showed a pattern of sporadic distribution, with the Tianshan Mountain as the boundary, high in the north, low in the south, and sporadic distribution. The supply/demand ratios of food production, water yield, and habitat quality showed a significant negative correlation with HAI as a whole. The supply/demand ratios of carbon storage, soil conservation, and greenfield leisure showed a significant positive correlation with HAI. The supply-demand ratios of food production, carbon storage, habitat quality, and greenfield leisure were mainly low-high clustered with HAI in the urban belt of the northern slope of Tianshan Mountain and the oasis area of Tarim River Basin, while the supply-demand ratios of soil conservation and water yield were mainly high-high clustered with HAI in the Tianshan Mountain Range and the Tarim River Basin.
