摘　　要：种植业碳足迹供需平衡分析是明确种植业碳减排方向的前提和基础。通过构建黄河流域及长江经济带种植业碳足迹及生态承载力账户,基于时空维度对其动态演化进行分析,并引入供需平衡指数表征其种植业碳资源供需现状。结果表明,黄河流域种植业碳足迹基本呈"M"型变动,长江经济带则呈逐年上升趋势。二者碳生态承载力均呈逐年上升趋势,耕地碳吸收功能不断增强,但上升幅度有所减缓。黄河流域内省际间种植业碳足迹相差较大,长江经济带差异值较小且总量值低于黄河流域。二者碳生态承载力中下游省份均高于上游省份。黄河流域供需平衡指数值均高于长江经济带,生态盈余省份所占比例均低于长江经济带。The supply and demand balance analysis of carbon footprint of planting industry is the premise and foundation of defining the direction of carbon emission reduction.In this paper,the carbon footprint and ecological carrying capacity accounts of planting industry in the Yellow River Basin and the Yangtze River Economic Belt were constructed,and the dynamic evolution was analyzed based on the spatial and temporal dimensions,and the supply and demand balance index was introduced to characterize the supply and demand status of carbon resources in the planting industry.The results showed that the carbon footprint of planting industry in the Yellow River Basin was basically“M”type,while that of the Yangtze River Economic Belt was increasing year by year.The carbon ecological carrying capacity of the two increased year by year,and the carbon absorption function of cultivated land increased continuously,but the rising range was slowed down.In the Yellow River Basin,there was a large difference in the carbon footprint of planting industry among provinces,and the difference value of the Yangtze River Economic Belt was small,and the total value was lower than that of the Yellow River Basin.The carbon ecological carrying capacity of the middle and downstream provinces was higher than that of the upstream provinces.The supply and demand balance index of the Yellow River Basin was higher than that of the Yangtze River Economic Belt,and the proportion of ecological surplus provinces was lower than that of the Yangtze River Economic Belt.
