摘　　要：生态足迹分析法是一种可持续发展程度的生物物理评价方法,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。应用生态足迹分析方法对兰州市的可持续发展状况进行评价,计算结果表明兰州市生态足迹需求总量大于生态足迹供给,表明在现有发展和消费水平下,区域发展超出了其生态系统可承受的范围,生态足迹需求以化石燃料和耕地为主,主要生态生产性土地均出现生态赤字,区域发展中的生态压力相对较大。Ecological Footprint 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. With the Ecological Footprint method, the Ecological Footprint of Lanzhou City in 2002 is calculated and analyzed. According to the results, the demand of ecological footprint of Lanzhou in 2002 was beyond the available ecological capacity, it shows that Lanzhou City is in a unsustainable status; the demand of ecological footprint takes petrochemical industry fuel and cultivated land as the core; the mainly productive land such as fossil fuel land ,cultivated land ,meadow land ,forest land and water areas present the ecological deficit ; the ecological pressure while developing in the area is relatively greatly.
