基于能源消费碳足迹的喀斯特山区低碳经济发展研究——以贵州省为例

Study on Development of Low-Carbon Economy in Karst Area Based on Carbon Footprint of Energy Consumption: A Case Study of Guizhou

采用碳足迹方法对贵州2000-2011年化石能源消费碳足迹的动态变化进行了定量分析。结果表明：贵州经济快速发展的同时，能源消费量不断增加。能源消费碳足迹从2000年的0．13hm^2／cap上升到2011年的0．31hm^2／cap，年均增长率为11．56％。消费碳足迹构成以煤炭为主。碳足迹产值由2000年的2．20×10^4CNY／hm。增加至2011年的5．38×10^4CNY／hm^2，年均增长率为12．02％。碳足迹生态压力也从从2000年的0．49增加到2011年的1．08，2011年为2000年的2．22倍。这揭示发展低碳经济的任务还很艰巨。文章根据研究结果提出减少能源消费足迹、缓解资源环境压力的对策建议，以期为责州节能减排和发展低碳经济提供参考依据。

Based on the model of carbon footprint, the paper calculates and analyzes the dynamic changes of fossil enemy consumption carbon footprint in Guizhou from 2000 to 2011.The results show that with rapid economic development, energy consumption has increased in Guizhou. The carbon footprint of energy consumption increases from 0.13 hm^2 per capita in 2000 to 0.31 hm^2 per capita in 2011; the annual average increasing rate is 11.56%. The carbon emissions in coal consumption is the main source of total carbon emission. The output value of energy consumption carbon footprint increases from 22 000 CNY per hm^2 in 2000 to 53 800 CNY per hm^2 in 2011, with an average annual growth rate of 12.02%. Ecological pressure intensity of carbon footprint has increases from 0.49 in 2000 to 1.08 in 2011, 2.22 times of 2011 to 2000. It is easy to see that developing a low carbon economy is still very difficult. According to the results, the countermeasures and suggestions are proposed to reduce energy consumption footprint, and relieve pressure of environmental resources, in order to provide reference for energy conservation and low carbon economic development in Guizhou Province.
