贵州岩溶地区能源生态足迹及其效率的动态变化评价

为了把握贵州岩溶地区的能源生态足迹和能源生态足迹效率的动态变化情况,文章采用基于生态足迹模型的能源生态足迹效率的定量研究方法,利用1978-2011年的历史数据计算,分析了贵州岩溶地区能源生态足迹和能源生态效率的动态变化特征。研究结果表明,在研究时段,贵州岩溶地区能源生态足迹和能源生态足迹产值呈阶段性递增趋势,能源生态足迹强度呈阶段性下降趋势,能源生态足迹产值虽有所提高,但仍低于全国平均水平。社会经济发展与能源足迹灰色关联分析结果表明,贵州岩溶地区经济发展与能源消耗关系十分密切,高能耗经济问题比较突出。 

Evaluation on the regime of energy eco-footprint and its efficiency in Guizhou karst area

In order to grasp the regime of energy eco-footprint and energy eco-footprint efficiency in Guizhou karst area, the regime features of energy ecological footprint and ecological efficiency are analyzed by means of the quantitative research methods of energy efficiency that based on the eco-footprint model from historical data (1978 - 2011) in Guizhou karst area in the paper. The results show that, during the study period, the energy eco-footprint and the value of energy eco-footprint tends to increase progressively, energy eco-footprint intensity tends to descend. The energy ecological footprint and its value in Guizhou, even through improved to some extent, is still lower than the national averaged level. Through gray correlation analysis on the social economic development and the energy eco-footprint, it is proved that the relationship of economic development and energy consumption is very close, so the problem of high energy consumption and economy is more outstanding in Guizhou karst area.
