摘　　要：生态足迹的理论和方法为度量区域可持续发展提供了新的审视角度。利用生态足迹模型,依据河南省2002年、2004年、2006年、2008年和2010年5个年份的统计资料,计算和分析了河南省生态足迹和生态承载力供给的变化,并在此基础上以省辖市为单位研究了2010年河南省生态足迹和生态承载力供给的空间分布格局。研究结果显示,河南省2002年、2004年、2006年、2008年、2010年的生态足迹始终大于其生态承载力,生态赤字呈扩大趋势,分别为3 194.04×104hm2、4 504.54×104hm2、5 167.95×104hm2、6 324.59×104hm2、7 323.16×104hm2,表明河南省的经济发展超越了其生态承载力供给范围,处于一种不可持续状态;空间上由于生态承载力供给和生态足迹分布不平衡,导致生态赤字在空间分布上也存在差异,生态赤字严重的地区主要集中在河南省中部及北部经济发展速度较快,以高耗能产业为主的一些省辖市。The theory and method of ecological footprint provides a new perspective for measurement of regional sustainable development. By using ecological footprint model,based on the statistical data of Henan Province in 2002,2004,2006,2008 and2010,the changes of ecological footprint and ecological capacity of supply was calculated and analyzed. And on this basis,according to the provincial cities as a unit,the spatial distribution pattern of ecological footprint and the supply of ecological capacity in Henan Province in 2010 were also researched. Results showed that the ecological footprint of Henan Province in 2002,2004,2006,2008,2010 is always greater than the supply of ecological capacity. Ecological deficit in this five years is widening,31 940 400 hm2,45 045 400 hm2,51 679 500 hm2,63 245 900 hm2,73 231 600 hm2in turn. The above shows that the economic development of Henan Province beyond the supply of ecological capacity,in a state of unsustainable. Due to the unbalanced distribution of ecological footprint and ecological capacity,ecological deficit also exists difference in the spatial distribution. The areas of ecological deficit seriously are mainly centralized in the middle and northern part of Henan Province,in these cities with high speed development and high energy- consuming industry.
