摘　　要：人类的生存与发展离不开能源,而能源大量消耗将会对环境产生严重影响,因此对能源消耗的碳足迹及生态压力进行研究具有重要意义。运用碳足迹的相关含义及研究方法,计算出2000—2010年四川省能源消耗的总碳足迹、不同能源和产业的碳足迹、碳足迹产值和生态压力值,并在此基础上利用STIRPAT模型进行岭回归函数拟合,进一步分析经济发展与能源消耗碳排放足迹之间的关系。结果表明:(1)四川省能源消耗的总碳足迹增长加快,从2000年的0.21hm2/人上升到2010年的0.53hm2/人,年均增长率为9.7%;(2)2000—2010年四川省能源消耗的碳足迹产值由2000年的3.3万元/hm2增加至2010年的5.5万元/hm2,年均增长率为5.2%;(3)碳足迹的生态压力从2000年的1.5上升为2010年的2.8,年均增长率为6.4%,对环境产生的压力越来越大;(4)四川省能源消耗的碳足迹与经济增长关系中虽呈现出环境库兹涅茨曲线的变化趋势,但目前尚未到达拐点,进一步证实能源利用对环境所造成的压力在不断增大。最后,针对存在的问题提出了相关对策与建议。Humanity＇s survival and development is heavily reliant on energy. Accompanied by the consumption of energy,a large number of environmental impacts will be produced. So it is important to study carbon footprint and ecological pressure. This paper used the relevant concepts of carbon footprint and the research methods to calculate carbon footprint of Siehuans total energy use,carbon footprint of all types energy and industry, carbon footprint of the output and ecological pressure from 2000 to 2010,and ridge regression function for STIRPAT model was applied to study the quantitative relationship between carbon emissions footprint of energy consumption and economic devel opment. The results show that the total carbon footprint is increased from 0.21 hm2/person to 0.53 hmperson dur ing 2000-2010,with the average annual growth rate is 9.7%. From 2000 to 2010,value of carbon footprint of energy use is increased from 33 000 yuan/hm2 to 55 000 yuan/hm2 ,with the average annual growth rate is 5.2%. Ecological footprint pressure increased from 1.5 in 2000 to 2.8 in 2010,with the average annual growth rate is 9.7% ,the pres sure on the environment is getting bigger. Kuznets curve appeared in the fitting results of the relation between carbon footprint of energy use and economic development, but it has not reached the inflection point at present, which further confirmed the fact that energy use brought increasing pressure on the environment.
