Dynamic Measurement of Ecological Footprint of Energy Resources and Its Economic Efficiency in Last Ten Years, China
中国1996年～2005年能源生态足迹与效率动态测度与分析

In this paper, the energy consumption in China from 1996 to 2005 was investigated using ecological footprint (EF). In addition, the dynamic characteristic of energy utilization in China is analyzed, and the value of energy footprint, the energy footprint intensity and the ecological pressure intensity of energy ecological footprint is also caculated. At last, we draw conclusion on development trend of energy consumption in China and give available ways for sustainable energy policies in the future. The results show that ecological footprint (EF) of coal consumption is dominant, which occupying 83.30% of the total in 1996, and 77.5% in 2005, with a trend of decrease. The EF of energy consumption for production also occupied a large proportion of the total, which was 83.30% in 1996, and 85.59% in 2005, with the trend of increase. As for the EF of energy consumption for daily life, the proportion decreased, 12.75% in 1996 and 10.48% in 2005. The value of EF of energy increases from 0.19×104 dollars/ha in 1996 to 0.33×104 dollars/ha in 2005. The intensity of ecological pressure of EEF decreases and the pressure index was 0.84 in 1996 and 0.63 in 1999. But it has increased continually since 2000, and reached 1.20 in 2005. These results indicate that the total EEF per capital is increasing continually along with the fast economic development. The EEF for production occupies large percentage of the total EEF, which is above 80%. The EEF of coal consumption is declining generally, and clean energy has been used with considerable scale. The value of EEF is increasing; the intensity of ecological footprint of energy is reducing gradually. Although the efficiency of energy utilization has been enhanced and energy structure has been improved, the EEF has heavy pressure on ecological environment. Another fact is that, although the intensity of EEF presents the tendency of decline, increased pollutant discharge will lead to enormous economic and environmental cost.
