新疆化石能源碳足迹及生态压力的动态研究

Dynamic on Carbon Footprint and Ecological Pressure of Fossil Energy in Xinjiang

利用碳足迹的概念和研究方法对新疆2002-2011年能源利用的碳排放、碳足迹、碳足迹强度、碳足迹产值和生态压力进行计算,结果表明,新疆能源利用的碳足迹在2002-2011年10年间呈现上升趋势,其中主要以煤炭的碳足迹占主导地位,石油次之,天然气最小;碳足迹产值呈现上升趋势,从2002年的0.93万元/hm^2增加到2011年的1.28万元/hm^2;碳足迹强度呈现下降趋势,从2002年的1.08 hm^2/万元下降到2011年的0.78 hm^2/万元;碳足迹生态压力逐年升高,从2002年的2.63增加到2011年的7.70。碳足迹分析结果反映出目前新疆经济发展状况良好,能源利用效率不断提高,但是经济发展也主要是依赖于能源的消费,能源消费过程中给生态环境带来的压力也越来越大。

The concepts of carbon footprint and research methods were used to calculate the carbon emissions,carbon footprint, value of carbon footprint, intensity of carbon footprint and ecological pressure of carbon footprint in Xinjiang from 2002 to 2011. The results showed that, the carbon footprint increased from 2002 to 2011, the carbon footprint of coal was the largest, followed by oil, and natural gas was the smallest. The value of carbon footprint of energy use increased from 9 300hm2 in 2002 to 12 800 hm^2 in 2011. The carbon footprint intensity of energy use decreased from 1.08 ×10^-4hm^2/per yuan in2002 to 7.8×10^-5hm^2/per yuan in 2011. The ecological pressure of carbon footprint increased from 2.63 in 2002 to 7.70 in2011. The analysis showed that the development of economic was good in Xinjiang, and the efficiency of energy use improved gradually, but the development of economic depended on the energy use, and the ecological environment pressure was increased continually.
