摘要
基于2006、2009、2012年统计数据,通过能值生态足迹的方法,对我国30个省份的能源消费进行了可持续性评价,并对能源消费与经济发展的关系做了初步探讨。结果表明,我国各省平均人均可再生能源承载力为5.34ha/人,人均能源消费生态足迹为13.58ha/人,生态盈余为-8.24ha/人,全国各省平均可持续发展指数为0.75。2006—2012年,能源生态赤字呈不断扩大趋势。2006—2012年,全国能源能值效率普遍提高,东部沿海城市能源效率较高。居民生活能源消费呈现出自东向西递减的趋势,反映出自然因素和社会经济发展因素的双导向作用。GDP总量与能源消耗能值线性相关。随着人均GDP增加,能源消耗总能值呈现倒"U"形,单位GDP消耗能源能值下降,居民生活能源能值消耗上升。总体上看我国经济发展依赖能源消耗,但随着经济发展,能源消费效率逐步提高,居民生活能源消费所占的比例逐步增大。
Based statistical data of 2006, 2009 and 2012, our study evaluated the sustainability of energy consumption of 30 provinces in China using emergy ecological footprint method and made a preliminary discussion on the relationship between the economic development and energy consumption. Results showed that the average renewable energy carrying capacity per capita in China is 5.34 ha/cap and ecological footprint per capita is 13.58 ha/cap, leading to an ecological surplus of 8.24 ha/cap. The average sustainable development index is 0.75. From 2006 to 2012, energy ecological deficit expanded gradually. Energy consumption increased with GDR With the increase of per capita GDP, energy consumption represented inverted ＂U＂ shape, GDP per unit energy consumption decreased and residents＇ living energy consumption raised. Overall China＇ s economic development rely on energy consumption. But with economic development, energy consumption efficiency improved gradually and residents＇ living energy consumption increased.
