In order to explore the current situation of carbon balance in Nanjing, with the above designated size industrial enterprises, 4993 residential communities and green areas as research objects, ArcGIS and ENVI software are used to spatially analyze the main carbon sources and carbon sinks in Nanjing. The calculation formulas of carbon sources and carbon sinks are used to calculate the carbon emissions and absorption of various districts in Nanjing, and compare the carbon balance of each district. The results show that: (1) the industrial and residential communities in Nanjing show the characteristics of agglomeration distribution; (2) the green land is mainly concentrated in the outskirts, which is mostly based on cultivated land; (3) the carbon balance coefficient of Nanjing city is 68, and all regions are in the carbon imbalance state, in which Qinhuai District is the most severe. Finally, from the planning point of view, suggestions for the construction of Nanjing City to improve the ecological environment of Nanjing and promote green sustainable development are proposed.
