摘　　要：利用生命周期法测算了我国各省区火电燃料消耗产生的CO2,CH4,SO2,NOx和烟尘排放量及相应的生态足迹,发现我国火电行业环境压力主要来自于CO2和NOx排放,二者合计比重达91.72%;各省区环境压力差异较大,环境压力与环境容量在空间上呈高度不均衡分布格局,不均衡因子多为东部发达城市或经济大省。研究结果为制订区域差别化的火电污染减排方案提供了参考依据。By use of life cycle method,this paper estimated emissions of CO2,CH4,SO2,NOx and dust from thermal power production.Furthermore,the corresponding ecological footprint was calculated.So we found that the pressure on the environment mainly came from the CO2 and NOx,and their proportion was 91.72 %.The environmental pressure difference among provinces was quite significant.The environmental pressures and capacity show a highly spatial uneven pattern and the uneven factors mostly were the eastern provinces.The results provide the references for regional ejection-decreasing program.
