摘　　要：减碳、节水是黄河流域可持续发展面临的重要问题。从水资源生态及碳足迹角度出发,将区域水碳关系进行耦合研究,有助于揭示水资源质量与碳排放之间的关系,为宁夏沿黄城市带实现生态环境保护可持续均衡发展提供指导。基于水资源生态足迹与碳足迹理论,从时空分布差异、水碳关联性特征入手,计算并分析了2010—2019年宁夏沿黄城市带4个中心城市的碳足迹、水资源生态足迹及其时空变化趋势。结果表明:区域内已经形成了以吴忠市-银川市为重心的碳排放和水生态压力区,且与经济高度发展区域有空间重合,但不同地区由于产业结构及资源条件的不同,碳排放与水资源的关联性差异明显,其中水质生态足迹与碳足迹之间的关联性更显著,呈现出水、碳、环境、产业等发展的区域不均衡性。Carbon reduction and water conservation are important issues that affect the sustainable development of the Yellow River Urban.From the perspective of water resources ecology and carbon footprint,the coupling study of regional water-carbon relationship will help reveal the relationship between the quantity and quality of water resources and carbon emissions,and provide some guidance for the sustainable and balanced development of ecological environment protection along the Yellow River Urban Belt in Ningxia.Based on the theory of water resources ecological footprint and carbon footprint,the carbon footprint,water resources ecological footprint and their spatiotemporal change trend of the four central cities along the Yellow River Urban Belt in Ningxia were calculated and analyzed from the perspective of spatiotemporal distribution differences and water-carbon correlation characteristics.The results show that a carbon emission and water ecological pressure region has formed,with Wuzhong and Yinchuan as the center of gravity,which overlaps with the highly developed region in the belt;however,due to the different industrial structure and resource conditions,the correlation between carbon emissions and water resources in different regions is significantly differentiated,among which the correlation between water quality ecological footprint and carbon footprint is more significant,showing the regional imbalance of water,carbon,environment and industry development.
