Correlation Between Land Use Change and Land Use Carbon Emissions from the County Perspective:A Case Study of Hohhot
To promote the low-carbon development and utilization of urban land,this study explores the correlation between land use change and land use carbon emissions in Hohhot by using land use dynamics,carbon emission calculation,and grey correlation degree.The followings are found from the research.(1)Construction land had the highest land use change degree in the study area with an average dynamic degree of 3.34%from 2010 to 2020,followed by unused land,cultivated land,grassland,water area,and woodland.The degree of land use change in Yuquan District was higher than those in other banners and counties.(2)The research on the carbon emission effect of land use shows that the carbon emission of construction land is the largest.The land use carbon emissions in Saihan District are the largest,and land use in Wuchuan County has the largest carbon sink.The net land use carbon emissions are the largest in Saihan District.(3)The correlation between land use change and land use carbon emissions is greater than 0.5.This indicates that land use change has a significant influence on land use carbon emissions,with construction land having the greatest influence,which is followed by water area,woodland,grassland,cultivated land,and unused land.Therefore,the change of construction land area has the greatest impact on land use carbon emissions.To alleviate the pressure of carbon emissions from construction land,reasonable planning and control of construction land expansion is necessary,and energy structure update is needed to enhance the use of renewable and clean energy.Additionally,efforts should be made to increase carbon sink land and protect woodland,grassland,man-made lakes,etc.,so that carbon sink reserves can be enhanced.
