摘　　要：我国以化石能源为主要燃料的火电生产导致了严重的资源枯竭和环境污染问题,定量评估火电燃料消费对资源环境的影响是区域可持续发展研究的重要内容。在估算火电燃料燃烧及运输、生产过程中排放的主要大气污染物的基础上,利用成分法计算相应的生态足迹,定量评估火电燃料消费过程对资源环境的影响。结果表明:我国1kW.h火电的燃料消费过程中排放的CO2、CH4、NOx、SO2、烟尘分别为1.07kg、9.93×10-3 kg、6.46×10-3kg、2.60×10-3 kg、2.02×10-2 kg;全国火电燃料消费占用的生态足迹由2000年的50 674.44万hm2,增加到2007年的123 842.08万hm2,年均增长13.62%;CO2和NOx的生态足迹平均比重高达83.6%,是影响资源环境的主要因子,SO2、烟尘与CH4三者合计仅16.4%,对资源环境的冲击相对较小。Fossil energy resources are the main fuel for China＇s thermal power.This has led to severe resource depletion and environmental pollution.It is an important part of regional sustainable development to quantitative evaluation of the impact of thermal power fuel consumption on resources and environment.Based on estimates on main atmospheric pollutants of thermal power fuel generation and transportation,the paper calculated the corresponding ecological footprint by using component method.The results show that during consuming 1 kW·h thermal power,CO2,CH4,NOx,SO2 and dust were 1.07 kg,9.93×10-3 kg,6.46×10-3 kg,2.60×10-3 kg,2.02×10-2 kg,respectively.China＇s ecological footprint of thermal power fuel consumption increased from 50 674.44×104hm2 in 2000 to 123 842.08×104hm2 in 2007.Average annual growth rate was 13.62%.The proportion of the ecological footprint of CO2 and NOx was as high as 83.6%.The total proportion of ecological footprint of SO2,dust and CH4 was only 16.4%,and the impact was small.
