摘　　要：土地用途转换是碳排放的重要来源。基于湖北省2000-2020年土地用途转换数据,计算碳排放量,研究其空间关联性特征。研究表明:湖北省土地用途转换率呈现“二增四减”的变化特征;土地用途转换导致碳排放量增加8577×104 t,增幅达到68%,主要源于单位GDP能耗的提高;空间上,碳排放量总体呈现“一个中心,半环递减”的格局;分区域来看,各地区土地用途转换碳排放量存在空间关联性,但空间关联处于低密度联结状态;武汉市始终处于碳排放量空间的中心和空间净受益的主导地位。Land use conversion is an important source of carbon emissions.Based on the land use conversion data from 2000 to 2020 in Hubei Province,this study calculates the carbon emissions and examines their spatial correlation characteristics.The findings indicate that the rate of land use conversion in Hubei Province shows a pattern of“two increases and four decreases”.The conversion has led to an increase in carbon emissions by 857.7 million tons,an increase of 68%,mainly due to the increased energy consumption per unit of GDP.Spatially,the overall pattern of carbon emissions presents a“central hub with a semi-circular decrease”.Regionally,there is spatial correlation in carbon emissions from land use conversion across different areas,but the spatial connections are of low density.Wuhan city remains at the center of carbon emissions and dominates in terms of net spatial benefits.
