Abstract: 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.

Key words: Yangtze River Economic Belt, Yellow River Basin, planting carbon footprint, ecological carrying capacity, supply and demand balance index
