摘要
[目的]研究近15年来长江三角洲能源消费碳足迹的时空变化。[方法]计算了1998～2013年长江三角洲地区化石能源消费碳足迹和碳足迹产值，并利用GIS技术研究了该地区16城市碳足迹的时空变化。[结果]长江三角洲能源碳足迹呈持续增长趋势，从1998年的0．19 hm2／人上升至2013年的0．54 hm2／人，年均增长速度为7．09％；长江三角洲碳足迹的空间格局分布呈中部高、南北部低的特征，高值主要分布在沪宁沿线城市；各市碳足迹总体呈增长趋势，但各市之间的差异较大。[结论]该研究为实现我国低碳发展提供了科学依据。
Abstract
Objective] To study spatial and temporal change of carbon footprint of energy consumption in the Yangtze River Delta during 1998-2013.[Method] The carbon footprint and its output value of fossil energy consumption in the Yangtze River Delta were calculated from 1998 to 2013.Based on GIS technology, the temporal and spatial variation of carbon footprint in 16 cities in the region were also investigated.[Re-sult] Carbon footprint of energy consumption in the Yangtze River Delta showed an upward trend, increasing from0 .19 hm2/person in 1998 to 0.54 hm2/person in 2013, with an average annual growth rate of 7.09%.Seen from the spatial distribution, the carbon footprint in the Yan-gtze River Delta was high in the center but low in the north and south.The high values were distributed mainly along Shanghai-Nanjing.On the whole, the carbon footprint in each city showed an increasing trend, but there were greet differences between the 16 cites.[ Conclusion] The research can provide scientific references for the realization of low-carbon development in China.
