兰州市公共交通的生态足迹测算研究

以兰州市公共交通(分为公交车和出租车两种)为研究对象,运用生态足迹法,测算2010年-2014年兰州市客运交通生态足迹,并计算兰州市公共交通的生态效率和生态足迹强度.结果表明:公共交通生态足迹年均占比为7.41%;公共交通生态足迹和客运量呈同步增长态势,公共交通生态足迹年均增长1.71%;在影响公共交通生态足迹的因素中,公交车和出租车的化石能源足迹年均占比分别为76.06%和62.32%;就生态效率而言,公交车生态效率是出租车生态效率的6.24倍.

Calculation ofEcological Footprint of Public Transport in Lanzhou City

Based on the public transportation( divided into bus and taxi) in Lanzhou, this paper uses the ecologicalfootprint method to calculate the ecological footprint of passenger traffic in Lanzhou City from 2010 to 2014 and calculates the ecological ef-ficiency and ecology of public transportation in Lanzhou City Footprint strength. The results show that the annual ecological foot-print of public transportation is 7. 41%, the ecological footprint and passenger volume of public transportation are increasing and the average annual growth rate of public transport is 1. 71%. Annual average fossil energy footprint for buses and taxis is 76. 06%and 62. 32%;for ecological efficiency, the bus eco-efficiency degree is 6. 24 times that of taxis.
