摘　　要：为助推城市低碳开发利用土地,通过土地利用动态度、碳排放量计算、灰色关联度等方法,探究呼和浩特市土地利用变化与土地碳排放之间的关联性。研究结果表明:(1)研究区的土地利用变化程度最大为建设用地,2010—2020年平均动态度达到3.34%,其次为未利用地、耕地、草地、水域、林地,玉泉区的土地利用变化程度高于其他旗县;(2)土地利用碳排放效应研究发现,建设用地的碳排放量最大,赛罕区的土地利用碳排放量最多,武川县的土地利用碳汇量最大,土地利用净碳排放量中赛罕区最大;(3)各地类变化与土地利用碳排放量变动的关联度均大于0.5,说明土地利用变化对土地利用碳排放有显著影响,其中,建设用地的影响最大,其次是水域,林地,草地,耕地和未利用地。因此,建设用地面积的变化对土地利用碳排放的影响是最大的,如要缓解建设用地带来的碳排放压力,一方面要对建设用地扩张进行合理的规划和管控,更新能源结构,提升可再生清洁能源的使用;另一方面增加碳汇土地,保护林地、草地、人造湖泊等利用类型,增加碳汇储备。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.
