采用生态足迹模型与分解分析模型,定量核算了1990—2006年辽宁省能源足迹,分析了其变动趋势及其影响因素。结果表明,1990—2006年,辽宁省能源足迹呈不断增大趋势,总量由3508万hm2增加到6491万hm2,人均值则由0.896hm2扩大到1.542hm2,增加了将近1倍,在区域生态压力中的贡献额为30%。在各类贡献因素中,经济发展对能源足迹的贡献远高于其他因素,其次为能源结构效应、人口规模效应,能源强度效应最低。虽然能源强度不断下降,但其对区域生态压力下降的贡献不足于抵消由能源结构不合理和消费水平的提高造成的生态影响,导致辽宁省能源足迹持续增加。
Using the ecological footprint model and decomposition analysis model, the energy footprint of Liaoning Province from 1990 to 2006 was quantitatively calculated, and its changing trend and its influencing factors were analyzed. The results show that from1990to2006, the energy footprint of Liaoning Province is increasing continuously, the total amount increases from 35.08 million hm2 to 64.19 million hm2, and the average value expands from 0.896hm2 to 1.542hm2, which nearly doubled. In the regional ecology The contribution to stress is 30%. Among all contributing factors, the contribution of economic development to energy footprint is much higher than other factors, followed by energy structure effect, population size effect, and lowest energy intensity effect. Although energy intensity is declining, its contribution to the decline of regional ecological pressure is not enough to offset the ecological impact caused by unreasonable energy structure and rising consumption level, resulting in a continuous increase of energy footprint in Liaoning Province.
