In order to improve energy conservation and emission reduction measures and reduce carbon emissions in Shaanxi Province,the temporal and spatial variation and spatial agglomeration characteristics of carbon emission and carbon emission intensity in Shaanxi province from 2000 to 2017 were analyzed by ArcGIS technology, spatial statistical analysis and spatial autocorrelation methods based on the view of city scale. The study found that the overall carbon emission of Shaanxi Province showed an increasing trend, the carbon emission intensity decreased significantly, and the number of urban areas in low carbon emission zones and high carbon emission intensity decreased significantly. Some cities became sub high carbon emission zones and high carbon emission zones. Yulin had the highest carbon emission and the fastest decline in carbon intensity. The carbon emission intensities of cities in Shaanxi Province had strong spatial autocorrelation. The intensity decreased gradually from north to south and showed a significant aggregation state, forming a trend of high aggregation in the northern urban area and low aggregation in the southern urban area.
