摘　　要：采用交通生态足迹理论,从城市规模层次上介绍了私人小汽车生命周期全过程生态足迹的计算方法,并计算出武汉市一辆私人小汽车生命周期生态足迹总量为40.44hm2,在小汽车的整个生命周期中,使用阶段的生态足迹值最大,占到了总量的79.94%以上。从生态足迹的计算项目来看,温室气体的排放所占用的生产性土地面积占总生态足迹的比例高达99.85%,温室气体的排放是私人小汽车对环境影响的主要因素。从时间序列计算了武汉市2003—2011年的生态足迹总量,发现有逐年增长的趋势。政府应合理限制私人汽车的数量,同时采取相应政策措施减少小汽车使用对于环境的污染。The ecological footprint theory is applied to introduce the ecological footprint calculation method of private ears life process and the total amount of ecological footprint of a private ear life cycle in Wuhan reaches 40.44 hm^2 ; in every life cycles of ears,the ecological footprint is largest and acceunts for above 79.94% of the total;seen from the calculation of eco- logical footprint,the productive land area occupied from sreenhouse gas emissions accounts for as high as 99.85% of the to- tal ecological footprint and the greenhouse gas emission is the contributing factor of cars impacting environment. The total amount of ecological footprint from 2003--2011 in Wuhan is calculated and it is found out that there exists the trend of increase year by year. The government should reasonably limit the number of private cars and meanwhile adopts relevant measures and policies to reduce environmental pollution of small cars.
