| 摘 要： | 运用生态足迹分析方法,对榆林地区1997、2001和2005年3个时间序列的生态足迹和生态承载力进行了计算和分析。结果显示：榆林地区1997、2001和2005年的生态足迹分别为1.047946、1.165550、1.866326hm2/cap,呈现出增长趋势,且增长幅度越来越大（1997～2001年增长11.2%,2001～2005年增长60.1%）;同时,该地区生态承载力呈现逆向变化,3年的生态承载力分别为2.036859、1.977902、1.807088hm2/cap,共降低11.3%;1997和2001年全区尚处于生态盈余状态,1997年生态盈余0.988913hm2/cap,2001年生态盈余0.812352hm2/cap,但到2005年全地区生态盈余消失,生态赤字0.059238hm2/cap。

| Abstract: | The ecological footprint method was used to calculate the ecological footprint (EF in short) and ecological carrying capacity of Yulin district.The results showed that EF in 1997,2001 and 2005 were 1.047 946,1.165 550 and 1.866 326 hm2/cap respectively.EF was growing up year after year and the extent increased more and more (increase 11.2%from 1997 to 2001,increase 60.1% from 2001 to 2005).Meanwhile,the ecological carrying capacity (EC in short) showed the opposite rule:in 1997,2001 and 2005,EC were 2.036 8... |
