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 prov...
