摘要
介绍了城市交通生态足迹的模型和方法,并以沈阳市为例对城市交通生态足迹、生态效率做了定量计算与分析.结果表明:沈阳市2004年交通生态足迹为35×104hm2,其中,能源消费间接用地占99%,而道路和场站直接用地仅占1%;从生态足迹构成看,小轿车和出租车生态足迹较高,分别为18.5×104hm2,5.61×104hm2,占交通总足迹的比例分别为53%,16%;从城市交通生态效率看,公共汽车最高,为3.06×104人次.hm-2,小轿车最低,为0.12×104人次.hm-2;从城市交通生态足迹强度看,小轿车最高,为8.38×10-4hm2.人次-1,公共汽车最低,为0.33×10-4hm2.人次-1.
The theory and method of ecological footprint （EF） were used to study quantitatively the sustainable development of urban traffic in Shenyang City. The results showed that in the year 2004 the urban traffic EF is 35 × 10^4 hm^2 among which the footprint of the energy consumption is up to 99 %, while the road surface is only 1%. In view of the structure of EF, car and taxi are 53% （about 18.5 × 10^4 hm^2）, and 16% （about 5.61× 10^4 hm^2）, respectively. However, in view of the ecological efficiency of urban traffic, bus is the top one up to 3.06 × 10^4 person-time＇hm-2, while car is the lowest one of all kinds of vehicles, only 0.12 ×10^4 persontime·hm^-1. The environmental pressure index of traffic shows that car is the highest in various vehicles, near to 8.38 × 10^-4 hm^2/person-time, while bus is the lowest, only 0.33 ~ 10^-4 hm^2/ person-time.
