【摘要】 森林能够产生包括固碳功能在内的大量生态效益,即使是用来生产木材的商用人工林,林木生长的长期性决定了其被全部采伐以前,也能够产生巨大的生态效益。基于这样的观点,本文认为在生态足迹理论与方法中,仅仅计算森林提供木材的直接效益,而将能够提供的化石能源用地作为0的计算方法是不正确的。论文用第6次全国森林资源清查的数据计算出2003年中国森林能够提供固碳作用的林地等量面积为人均0.1663 ghm2,约是同时期全部化石能源足迹的20%;中国林业固碳作用林地的供给潜力等量面积为人均为0.27 ghm2,使化石能源生态赤字可降低约33%。计算我国能源消耗和化石能源用地供给的状况,结果表明在不同省份之间能源消耗和提供的化石能源用地的状况也有很大差距。经济发达、森林资源比较少的地区,能源生态足迹较大,而在经济不发达、森林资源比较多的地区,能源足迹较小。更多还原

【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 ghm~2 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.更多还原
