摘　　要：生态足迹分析法因其基于生态生产性土地的量化指标、新颖的思路和简便的计算方法以及较为科学、完善的理论体系及方法本身的普适性而日益流行。应用该方法对兰州市的可持续发展状况进行了评价,兰州市人均生态赤字为1.692 88,其生态足迹是当地生态供给的近7倍,表明在现有发展和消费水平下,对生态系统的压力大,其发展超出了生态系统可承受的范围。并据对计算结果的分析提出了实现可持续发展的相应建议。生态足迹法自提出以来,在全球、国家及区域可持续发展评价中得到广泛应用,通过在兰州市的实际应用,对西北干旱区城市的可持续状况从侧重生态的角度进行了评价。The measure of sustainable development has always been an important but difficult subject. The ecological footprint is initiated by William E. Rees, Canadian ecological economist, and Wackernagel Mathis, the former＇s postgraduate . It is a new method includes biophysical assessments and get rid of some defects of the other models to quantify and analysis sustainable development, on account of its scientific theory, innovative thoughts and wide adaptability, it becoming more and more popular in recent years. Human consume the products and Services of nature, not only economic activities and resources used on life, ecological aggradations capacity of assimilating waste materials, but also many non-consuming life-supporting services, every one of us has an impact on the earth. Does the human load stay with in global carrying capacity？ The concept of ecological footprint has been designed to answer this question. It evaluates human activity effect on the global ecosystem by quantifying the biologically productive areas necessary to maintain human survival. With the Ecological Footprint method, the Ecological Footprint of Lanzhou region in 2002 is calculated and analyzed. According to the calculation, the ecological deficit of Lanzhou is 1. 69288, ecological footprint is 7 times of the ecological capacity. It shows that Lanzhou is in a unsustainable status. At the same time, according to the analysis on result of calculation, puts forward corresponding suggestions of realizing sustainable development. Since Ecological Footprint has been proposed, it used widely in the whole world, country and regional sustainable development study. Through the practical application in the area of Lanzhou, quantified the pressure and effect of city economic activities on natural ecosystems in Northwest area.
