摘　　要：基于生态足迹理论模型,定量测度并分析了河南省1995-2008年生态足迹及化石能源利用效率的动态变化。研究结果表明:1995-2008年间河南省人均生态足迹从1.295 hm2迅速增加到2.613 hm2,是1995年的2.017倍,而同期生态承载力仅增长了47%,导致人均生态赤字在14 a间增长了1.34倍,其中化石能源足迹对人均总足迹和生态赤字的贡献率最大;化石能源足迹产值呈增加趋势,2008年为2.891 5万元/hm2,比1995年增加了1.495万元/hm2;2008年化石能源足迹强度最低,为0.345 8 hm2/万元,仅是1995年的48%;化石能源足迹对生态系统的压力指数1996-1999年逐步下降,随后持续上升并于2006年增长到最高值20.11。这说明河南省社会经济发展对资源的需求超过自然环境的再生能力,虽然化石能源利用效率有所提高,但其消费规模的大幅增加及化石能源承载力的有限改善,导致河南省域生态压力持续攀升。Based on the ecological footprint theoretical model,this paper quantitatively measured and analyzed the dynamic changes of ecological footprint and fossil energy economic efficiency.The results show that the ecological footprint in He＇nan Province has been increasing from 1.295 hm2 to 2.613 hm2 in 2008,which is 2.017 times that of 1995,while the ecological capacity just increases by 47% at the same time,which leads the pre ecological deficit increases by 3.14 times during 14 years,the fossil energy footprint is the greatest contribution in pre ecological footprint and ecological deficit.The economic value of fossil energy footprint（VEF） has been the growing trend from mid-1990s;the VEF in 2008 is 2.891 5 millon yuan/hm2 that increases by 1.495 yuan/hm2 than 1995.Fossil energy footprint intensity（FEFI） continues to reduce,and the FEFI in 2008 is 0.345 8 hm2/millon yuan which is the lowest level that was just 48% that of 1995.The ecological pressure intensity of energy footprint（EPIEF） was being gradual decline during 1996-1999,then continued to grow,and reached the highest level 20.11 in 2006.We can conclude that the resource demand in the course of social and economic development in He＇nan has surpassed the regeneration of natural environment.Though the economic efficiency of fossil energy has been improved,its consumption scale increased and fossil energy capacity improvement limited,which caused that the ecological stress has been rising in He＇nan province.
