低碳经济发展需要在区域协调下有效进行，这需要全面考虑城市之间工业碳排放的差异。随着全球工业化的飞速发展，越来越多的研究人员开始关注工业过程中的碳排放问题。近年来，许多学者都研究了全球以及国家等不同尺度碳排放的时空分布特征。这其中，标准偏差椭圆法（SDE）被用来量化和总结空间特征。该方法可用于测量特定生产活动分布的方向以及空间趋势。但目前，关于区域间碳排放的研究大都集中在国家和省级尺度，城市尺度的碳排放分析没有得到足够的重视，这不利于减排目标的进一步分解。在这种情况下，本研究主要关注两个研究问题。首先是从城市层面的能源消耗和水泥生产过程两个方面揭示工业碳排放的空间分布，其次是使用趋势分析和SDE方法描述碳排放的动态特征。

英文摘要：

Research on the dynamic distribution characteristics of carbon emissions and their evolution patterns is of importance to unify carbon reduction targets. This study aimed to measure the industrial carbon emissions by energy consumption and the cement production process in Guangdong from 2005–2015, and it empirically analyzed the distribution dynamics and evolution of the inter-regional carbon emissions. It concludes that, there was significant spatial non-equilibrium in the industrial carbon emissions, the carbon intensity in the Pearl River Delta (PRD) was less than that of the peripheral cities, and the results showed that the overall gap in the spatial distribution of the industrial carbon emissions showed an expanding trend with its evolution to the east. Among them, Northern Guangdong showed a downward trend. The carbon emissions of the PRD were greatly reduced with the external strong radiation. The carbon emission reduction policies should be tailored to local conditions according to the development levels.
