Against the backdrop of rapid economic growth,ecological and environmental problems are particularly prominent,and carbon emissions from land use change are the main factor of global warming.This article is from a city perspective,this paper constructs a comprehensive evaluation model and a carbon emission measurement model,analyzes its spatio-temporal evolution characteristics,and on this basis,uses geographic detectorsto explore the impact mechanism of land use recessive transformation on carbon emission intensity,and puts forward scientific suggestions on green,low-carbon emission reduction.The results show:In Jiangxi Province,the level of land use recessive pattern continued to rise and changed to a higher order pattern,and the northern region gradually evolved into a dual-core aggregation pattern.The net carbon emissions in the study area increased year by year,showing a significant difference in space,showing a north-south high,middle and low differentiation.Expansion of construction land encroaches on a large amount of agricultural and ecological land,which weakens the carbon sequestration function of land.The driving forces of factors affecting carbon emission intensity vary greatly in different periods,but the investment of fixed assets and the electricity consumption of the whole society are always the key driving forces,and there are other leading factors in each stage.Optimizing land use form,reforestation and strengthening ecological construction are of great significance to carbon emission reduction.Scientific layout of industrial structure,industrial green transformation as a top priority,accelerate the cultivation and expansion of green and low-carbon industries,and promote green and low-carbon development in Jiangxi Province.
