摘要
基于生态足迹思想提出碳足迹和碳承载力概念,对甘肃省1995-2009年化石能源消费的碳排放和植被的碳承载力进行定量分析。结果表明:甘肃省化石能源消费的碳足迹由1995年的2 466.12×104 t C增长到2009年的4 464.47×104 t C;煤炭消费的碳足迹最大,其次为石油,天然气比重最小,2009年的比重分别为81.54%、15.20%和3.26%;碳承载力由1995年的1 158.89×104 t C增长到2009年的1 472.19×104 t C,其中,森林的碳承载力最大,其次为草地,农田最小;甘肃省能源消费碳足迹远高于生产性土地的碳承载力。伴随着碳足迹的高增长率,碳赤字持续增大。
The concepts of carbon footprint and carbon bearing capacity were introduced based on the idea of ecological footprint. Quantitative analysis was conducted on the carbon emission of the fossil energy and carbon bearing capacity of the vegetation in Gansu Province during 1995 to 2009. The results showed that the carbon footprint of the fossil energy consumption of the province increased from 2 466.12 × 10^4 t C in 1995 to 4 464.47 × 10^4 t C in 2009, in which coal consumption consisted the largest proportion, followed by petroleum and natural gas, which accounted for 81.54%, 15.20% and 3.26%, respectively in 2009. Carbon bearing capacity of the vegetation increased from 1 158.89×10^4 t C in 1995 to 1 472.19×10^4 t C in 2009, of which carbon capacity of forest was the largest, followed by grassland, and farmland, indicating that the carbon footprint caused by fossil energy consumption was much higher than carbon bearing capaci- ty of productive land. With high growth rate of carbon footprint, carbon deficit increased continuously.
