Abstract:

Forest include artificial commercial forests is able to provide great ecological benefits of forest carbon sequestration and others from its long time of growth before be logged. Based on this, it was pointed out in this paper that the most of current researches on footprint take fossil energy land supply as zero without consider the situation of forest in growing period can provide a great deal of environment benefits is not proper. It was calculated in this paper based on the data of China's sixth forest resource inventory and the energy consumption statistics data in 2003 in the way of treated standing forest as source of environment benefit supply in that China's forest was able to provide 0.166 3 ghm² per capita as fossil energy land supply to take 20% of total energy footprint and the potential which was 33% forestation on all forest lands. The energy footprint and fossil energy land supply data in provincial level was counted and shown that the gap between developed provinces with little forest resource to that of developing provinces with rich forest resources were great.

Key words: ecological footprint, energy footprint, fossil energy land supply, forest carbon sequestration
