区域能源利用的碳足迹及其对生态经济影响分析

运用碳排放足迹的相关含义以及研究方法估算了2004—2008年江苏省能源利用的总碳排放、总碳足迹、碳足迹的产值与强度以及生态压力,提出了相应的管理策略。研究结果表明:总碳排放从2004年的41793.07万t上升到2008年的64750.84万t,一直呈现上升的趋势;总碳足迹由2004年的0.87hm2/人上升到2008年的1.30hm2/人,呈现上升的趋势;煤炭利用的碳足迹最大,石油次之,天然气与煤气所占比例较小;碳足迹产值从2004年的2.33万元/hm2增加到2008年2.66万元/hm2,碳足迹生态压力从2004年的193.77上升到2008年的307.64。

This paper used the relevant concepts of carbon footprint and research methods to calculate the total carbon emissions, total carbon footprint, value of carbon footprint, carbon footprint intensity and ecological pressure intensity of carbon footprint of Jiangsu Province from 2004- 2008, and finally put forward the corresponding management strategies. The study results showed that： the total carbon emissions increased from 417.93 million tons in 2004 to 647.51 million tons in 2008; the total carbon footprint from 0.87 hm^2/p in 2004 rose to 1.30 hm^2/p in 2008; The carbon footprint of coal use was the biggest, followed by oil, and natural gas and gas took a smaller proportion;value of carbon footprint of energy use increased from 233 thousand/m^2 in 2004 to 26.6 thousand/hm^2 in 2008; ecological pressure also increased from 193.77 in 2004 to 307.64 in 2008.
