Regional carbon budget and compensation are one of the current research hotspots, which is great practical significance for dealing with climate change promoting coordinated development low carbon. Based on energy consumption land use data, a measurement model was established to analyze characteristics spatial differentiation 11 prefecture-level cities in Jiangxi Province from 2010 2020 carry out functional zoning, further calculate value each city. The results showed that (1) during study period, emissions an increasing trend, average annual growth rate 6.00 million tons, showing distribution pattern “high west east.” province mainly represented by net sources. (2) During forest main sink. sink absorption capacity declined 60.56 tons 59.69 2020. (3) regional difference economic contribution coefficient relatively tiny. ecological support has apparent heterogeneity, feature south north.” (4) could be divided into four regions: area, low-carbon optimization total control intensity area. By calculating according value, high-compensation areas, three low-compensation compensated areas. larger is, higher amount; conversely, smaller budget, more amount can obtained. According above conclusions, should improve emission reduction mechanisms strengthen management utilization. Meanwhile, formulate differentiated development, strategies developed promote low-carbon, coordinated, sustainable among regions.
