摘　　要：采用碳排放系数法计算长三角地区建筑业碳排放量,运用slope指数、泰尔指数和对数平均迪氏指数法(LMDI)等方法分析长三角地区26市建筑业碳排放的空间差异、演变特征及驱动因素.结果表明:(1)2004~2020年间,长三角地区建筑业碳排放先增长后波浪式变化,整体呈东高西低的空间格局;(2)长三角建筑业碳排放总体差异有所减小,呈现出先波浪式上升后逐渐减小的趋势,且长三角省域内差异大于省际间差异对总体的贡献;(3)驱动因素中,经济发展效应、房屋施工面积效应促进碳排放增加,人口密度效应、能源消费强度效应、能源结构强度效应则呈抑制作用.The carbon emissions of the construction sector in the Yangtze River Delta region were calculated using the carbon emission coefficient method in this paper.The spatial variations,evolutionary characteristics,and driving factors of carbon emissions across 26 cities in the Yangtze River Delta were analyzed using the slope index,Theil index,and Logarithmic Mean Divisia Index(LMDI).The results indicated that between 2004 and 2020,the carbon emissions from the construction industry in the Yangtze River Delta were first increased and then exhibited a wave-like fluctuation,overall presenting a high-in-the-east and low-in-the-west spatial pattern.The overall disparity in carbon emissions within the construction sector of the Yangtze River Delta was diminished,first showing a wave-like increase and then a gradual decline.Notably,within the Yangtze River Delta region,the intra-provincial discrepancies contributed more to the overall variance than the inter-provincial discrepancies.Among the driving factors,the effects of economic development and housing construction area promoted the increase in carbon emissions,while factors such as population density,energy consumption intensity,and energy structure intensity played a suppressing role.
