| 摘 要： | 运用生态足迹方法计算出1990—2007年中国能源消费的生态足迹。在此基础上,分析了能源足迹强度(EFI)、能源足迹生态压力(EPIEF)的时空动态变化特征。结果表明,近20年来我国能源足迹波动上升,能源消费结构有所改善,但煤炭足迹仍占主导,近几年又有回升趋势;能源足迹强度呈幂指数衰减,能源利用效率不断提高;EPIEF呈上升趋势,说明能源利用对自然生态系统的压力逐渐增大。在空间分布上,各省区能源足迹差异显著,能源足迹强度由西向东逐渐降低,而EPIEF则由西向东呈增大趋势。依据EPIEF指数将中国30个省区划分为能源足迹生态盈余区(EPIEF1)、生态轻度亏损区(1EPIEF5)和生态严重亏损区(EPIEF5)3种类型。

| Abstract: | In this paper,energy ecological footprint(EEF) in China from 1990 to 2007 was calculated.On this condition,spatial-temporal dynamic characteristics of energy footprint intensity(EFI) and ecological pressure intensity of energy footprint(EPIEF) were analyzed.The result showed that during the past two decades,EEF in China showed fluctuation increased trend,consumption structure of energy was improved,whereas proportion of coal footprint was also major and becoming rising in recent years.EFI showed exponential... |
