摘　　要：基于区域环境扩展型投入产出模型,对黄河流域水-土-能-碳资源消耗及足迹流动、区域资源及碳排放流通状况、水-土-能-碳网络特征进行了模拟分析。结果表明:2017年黄河流域九省区水资源消耗总量为1 073.69亿m^(3),占用土地面积为266.69万km^(2),能源消耗为6.95亿t(标准煤),碳排放量为31.57亿t。在流域内部足迹流动中,河南水、土、能、碳足迹均最大,综合循环利用率最高;宁夏是最大的虚拟水资源供应地;山西能、碳足迹调出量最大;山东土地足迹循环利用率最高;青海是主要的水、土、能资源供应地,四川承接了黄河流域19.3亿t碳足迹。黄河流域水-土-能-碳关联系统的生态关系主要以竞争关系为主,控制、掠夺关系占比较小,无互利共生关系;水-土-能-碳关联系统的生态关系处于高冗余、低效率状态,能源网络的效率最高。Based on the regional environmentally-extended input-output model,the resources consumption and footprint flow of water-land-energy-carbon in the Yellow River Basin,the circulation of regional resources and carbon emissions,and the characteristics of water-land-energy-carbon network were analyzed.The results show that in 2017,the water consumption of nine provinces in the Yellow River Basin was 1073.69×10^(8) m^(3),the occupied land area was 266.69×10^(4) km^(2),the energy consumption was 6.95×10^(8) t of standard coal,and the carbon emission was 31.57×10^(8) t.In the internal footprint flow of the Yellow River Basin,Henan Province has the largest water,land,energy,and carbon footprints and the highest comprehensive recycling utilization rate.Ningxia is the largest virtual water resource supply area.Shanxi Province has the largest transfer of energy and carbon footprints.Shandong Province has the highest land footprint recycling utilization rate.Qinghai Province is the main source of water,land,and energy resources.Sichuan Province has undertaken 19.3×10^(8) t of carbon footprint in the Yellow River Basin.The water-land-energy-carbon system in the Yellow River Basin is dominated by competition,with less control and plunder,and without mutualism.The water-land-energy-carbon correlation system is in a state of high redundancy and low efficiency,and the energy network has the highest efficiency.
