Abstract:

Using the carbon footprint model, the carbon footprint of energy consumption and the ecological pressure of carbon footprint were analyzed from 2003 to 2013 in Xingtai City, Hebei Province, China. The results show that, in Xingtai City, the energy consumption was increasing during the past 10 years, with the consumption of fossil energy resources accounting for around 50% of total consumed energy. In the consumption of fossil energy, coal was primary energy. This is an inevitable result from the policies of coal supply. The per capita carbon footprint from total energy consumption and the per capita carbon footprint from coal consumption increased in a fluctuation way. The per capita carbon footprint from petroleum consumption changed slightly. The change of per capita carbon footprint from gas consumption showed a fluctuation stage, and then followed a sharp increase stage. The ecological pressure of carbon footprint show an increasing tendency, suggesting that CO2 production from the energy utilization has been far beyond the absorptivity of woodland. Therefore, the paper proposes feasible means and corresponding countermeasures on energy utilization and industrial structure in the future, which would provide the strategy-making reference for the continual development in optimization energy structure and establishment the low-carbon economic development model in Xingtai City.

摘要：

采用碳足迹模型, 分析2003—2013年邢台市能源消费碳排放足迹和碳排放足迹生态压力的动态变化。结果表明: 近10年来邢台市能源消费量逐年增多, 在总能源消费中, 化石能源消费所占比例在50%上下, 在化石能源消费中, 仍以煤炭消费为主, 这是受长期以煤炭为主要能源供应政策影响的必然结果; 人均总碳排放足迹与煤炭人均碳足迹呈波动增加的趋势, 石油人均碳足迹虽然有波动, 但总体变化不大, 天然气人均碳足迹呈现波动和快速上升两个阶段; 碳排放足迹生态压力总体为增加态势且其值大于1, 说明在能源利用过程中产生的CO2 远超出林地所吸纳的量。对邢台市未来的能源利用及产业结构提出相应的可行性对策, 以期为优化能源利用结构和构建低碳经济发展模式, 实现可持续发展提供科学的决策依据。
