The study of spatial and temporal pattern analysis of urban land use carbon emissions and carbon balance zoning is of great importance for achieving carbon emission reduction and"dual carbon"goals.Taking 46 counties and cities in northern Xinjiang as the study area,using land use and energy data,the carbon emission coefficient method was used to calculate land use carbon emissions from 2000 to 2020,analyze the spatio-temporal evolution of carbon emissions,and make carbon balance zoning for each county and city.The results showed as follows:(1)Carbon emissions showed an overall upward trend,and an exponential upward trend from 2016 to 2020.Carbon uptake decreased slowly,carbon emission intensity decreased first and then increased,and carbon emissions were much higher than carbon uptake.(2)Carbon emission mainly comes from construction land,cities on the north slope of Tianshan Mountain are the main carbon emission cities,carbon absorption mainly comes from grassland and forest land,and the Ili Valley and the southern Altai Mountain are the main carbon absorption cities.(3)The spatial correlation of carbon emissions gradually weakened,the hot spots were concentrated in the vicinity of Karamay City,and the cold spots were concentrated in Ili Prefecture and Altay Prefecture.(4)According to the economic contribution coefficient,ecological carrying capacity coefficient and carbon emissions,it can be divided into five carbon balance zones:carbon sink function zone,carbon sink optimization zone,low-carbon economic zone,carbon source optimization zone and high carbon control zone.
