摘　　要：应用生态足迹理论与方法,对绥宁县国家级生态示范区可持续发展进行度量分析结果表明,2001年绥宁县人均生态足迹为1.517888hm2,人均生态足迹供给(生态承载力)为1.286877hm2,人均生态赤字为0.231011hm2,绥宁县生态经济发展处于不可持续状态;其2005年、2015年生态足迹分别为1.343577hm2、1.328835hm2,生态承载力分别为1.320071hm2、1.423893hm2,生态盈亏分别为-0.023506hm2、0.095058hm2,万元GDP生态足迹值分别为2.46hm2、0.83hm2,生态承载发展度分别为0.98、1.07。实施生态示范区建设可使该县生态赤字、万元GDP生态足迹值逐渐减小,生态承载发展度逐渐增大并达1左右,能源消费结构逐渐优化,资源得到合理利用,社会经济迈入可持续发展轨道。The measure of sustainable development of Suining national eco-demonstration area was studied. The results show that the ecological footprint per cap. was 1. 517888hm^2, the ecological carrying capacity was 1. 286877 hm^2 and the ecological deficit was 0. 231011 hm^2 in 2001 ,showing that the social economy of Sulning County was not sustainable. But after eco- demonstration area construction, the ecological footprint will be 1. 343577 hm^2, 1. 328835 hm^2 , the ecological carrying capacity 1. 320071 hm^2, 1. 423893 hm^2 ; the ecological surplus 0. 023506 hm^2, 0. 095058 hm^2 ; the ecological footprint per 10000 yuan GDP 2.46 hm^2 ,0.83 hm^2 ;the ecological carrying ratio 0.98,1.07 in 2005 and 2015 respectively. The ecological deficit and ecological footprint per 10000 yuan GDP become decreasing, the ecological carrying ratio becomes increasing and reaches about 1 after eco-demonstration area construction, which makes resources utilization and energy constructure optimization, social economy becomes sustainable.
