基于2008-2020年长江三角洲城市群27个地级市建筑部门碳排放数据,采用探索性空间数据分析(ESDA)模型和GTWR-STIRPAT模型分析城市群建筑部门碳排放的时空格局及其影响因素的时空异质性.结果表明:①时间上,2008-2020年长江三角洲城市群建筑部门碳排放持续增大;空间上,城市群建筑部门碳排放大体呈现"中间低、南北高"的分布格局.②城市群建筑部门碳排放空间聚集效果明显,主要呈现"低-低"、"高-高"的空间聚集特征.③各影响因素在不同城市存在较强的时空异质性,能源消耗强度、人口总量、建筑产业结构和人均GDP对城市群各市建筑碳排放具有正向影响,而城镇化水平和建筑减排政策数量对城市群大部分城市具有负向影响.最后提出了城市间联防联控措施和差异化减排建议.
Spatiotemporal pattern and influencing factors of carbon emissions from construction sector in the Yangtze River Delta urban agglomeration
Based on the carbon emission data of construction sector in 27 prefecture-level cities of the Yangtze River Delta urban agglomeration from 2008 to 2020,the spatial and temporal pattern of carbon emission from construction sector and the spatio-temporal heterogeneity of its influen-cing factors were analyzed by using the ESDA model and the GTWR-STIRPAT model.The re-sults showed that:①From 2008 to 2020,carbon emissions from the construction sector in the Yangtze River Delta urban agglomeration continued to increase;spatially,carbon emissions from the construction sector in urban agglomerations generally show a distribution pattern of"low in the middle and high in the north and south".②The spatial aggregation effect of carbon emissions from the construction sector in urban agglomeration is obvious,mainly showing"low-low"and"high-high"spatial agglomeration characteristics.③ The influencing factors are of strong spatio-temporal heterogeneity in different cities.Energy consumption intensity,total population,con-struction sector structure and per capita GDP have a positive impact on the carbon emissions of the construction sector in urban agglomerations,while urbanization level and the number of building emission reduction policies have a negative impact on most cities in urban agglomera-tions.Finally,joint prevention and control measures between cities and differentiated emission reduction suggestions are put forward.
