1996-2010年中国能源碳足迹生态压力研究

The ecological pressure intensity of carbon footprint in China from 1996 to 2010

文中基于能源碳足迹及其相关理论和研究,定量分析了1996-2010年间中国能源碳足迹生态压力的变化,并对能源碳足迹生态压力与人均GDP进行脱钩分析。结果显示:从1996-2010年间,由于煤炭和石油的大量使用,中国能源碳足迹从50,766hm2增加到116,920hm2,增长2.303倍。能源碳足迹生态压力从0.97hm2/hm2增加到1.96hm2/hm2,增加2.021倍,现有森林和草地的面积远远不能够满足日益增加的能源碳足迹。能源碳足迹生态压力与人均GDP之间主要表出弱脱钩的关系,脱钩指数大体上经历了先快速上升、后持续下降的过程,最终稳定到0.2左右,这表明:经历了初期的波动之后,现阶段中国能源碳足迹生态压力与人均GDP的弱脱钩关系是连续和稳定的。

China＇s ecological pressure intensity of carbon footprint from 1996 to 2010 was analyzed, and the de- coupling analysis between per capita GDP and ecological pressure intensity of carbon footprint was done. The re- suits showed that from 1996 to 2010, Due to the over use of coal and oil in China, energy carbon footprint had in- creased from 50,766hm2 to 116,920hm2, increased 2. 303 times. Ecological pressure intensity of carbon foot- print continued to increase from 0.97hm2/hm2to 1.96hm2/hm2, increased 2. 021 times. China was mainly in weak decoupling stage in the past for a long time. The decoupling index experienced rising firstly and falling late- ly, finally being stable, which means that the weak decoupling in China is stable.
