摘　　要：当前,可持续发展已经成为人类的共识。在诸多可持续发展评价模型中,生态足迹模型以其计算简单、结果明了得到了广泛的应用,但其在理论和方法上存在一些缺陷。为了弥补传统生态足迹在区域可持续发展评价中的不足,将能值分析理论与生态足迹方法结合,对甘肃省2000-2008年可持续发展状态进行评价。发现:①2000-2008年甘肃的人均生态承载力基本维持在55.5～63 hm2,且有逐年下降趋势;②生态足迹以年均10.6%的速度快速上升;③生态赤字以年均10.6%的速度快速增长;④能源资源的持续高消费是造成生态赤字扩大的主要原因。基于上述研究结论,提出了促进甘肃省可持续发展的策略。Sustainable development has become as a common view in the world.Along with rapid economic development and population growth,a series of contradictions,such as ecological degeneration and land degradation,have to be faced.In order to maintain the sustainable development,humanity must live within the limits of natural carrying capacity.In the 1990s,Rees and Wackernagel put forward an ecological footprint model,in which an easy and rapid method was offered to measure the environmental situation of eco-economic system.In the theory and method,however,there are some shortcomings to evaluate regional sustainable development.Energy theory offered by Odum H T was applied widely to track energy flow and evaluate ecological benefits and economic returns in eco-economic system.In this paper,the energy analysis and the conventional ecological footprint model were used to quantitatively evaluate the ecological footprint in Gansu Province during the period from 2000 to 2008.The results are as follows：（1） During the period from 2000 to 2008,the per capita ecological carrying capacity in Gansu Province was maintained at 55.5-63 hm2 and was in a decrease trend;（2） The ecological footprint was rapidly increased with an average annual increase rate of 10.6%;（3） The ecological deficit was rapidly increased with an average annual increase rate of 10.6%;（4） Continued high consumption of energy resources was the main cause resulting in the ecological deficit.Based on the conclusions above,some strategies were put forward for promoting sustainable development in Gansu Province.
