Monitoring, evaluation and spatio-temporal analysis of carbon emissions from urban building operations at the microscale
At present,there are some problems in the research of urban carbon emissions,including the lack of consideration for urban expansion factors and the insufficient research scale,which ignore the spatial heterogeneity of the carbon emission phenomenon,and these problems can easily lead to extensive management of "dual carbon". Based on the narrow accounting method of building carbon emissions,this paper integrated statistical data on building electricity and gas energy consumption, urban development boundaries,point of interest(POI) and planning data to finely map and spatio-temporally analyze the distribution and intensity of urban building carbon emissions. The results show that from 2010 to 2020,the study area experienced an urban expansion of 63.5％,and total carbon emissions increased by 3.74 times. Industrial land,residential land and commercial land are three types of urban functional areas with high carbon emissions,where carbon emission spatial movement and blowout phenomena have occurred with industrial transfer and urban renewal.At the same time,more than half of the expansion areas are low-carbon emissions,which is related to social and economic phenomena such as inefficient land use and low residential occupancy rates in the expansion areas.The results of this study provide a reference value for decision-making departments to conduct refined carbon emission management work.
