摘　　要：从列车牵引用电和地铁站场用电两方面分析了深圳地铁的碳排放量。计算出深圳地铁2008年牵引用电量为2514万度,2009年为2635万度;地铁站场2008年的用电量为1.08亿度,2009年为1.12亿度。其次,根据南方电网单位电力碳排放量计算出深圳地铁2008年的碳排放量为28053.695 t,旅客人均耗电量为0.984度,旅客人均碳排放量207.025g;2009年为碳排放量28572.561 t,旅客人均耗电量为1.002度,旅客人均碳排放量206.697g。然后,与深圳公交、出租车和香港地铁进行了比较。2008年,由于运量客较少,深圳地铁的旅客人均碳排放量,约为出租车的46%,是深圳公交大巴的1.99倍、中巴的1.26倍。此外,深圳地铁的旅客人均耗电量与香港地铁大致相当,由于香港地铁所用电力的碳排放较低,使得深圳地铁旅客人均碳排放量是香港地铁的1.24倍。最后,对2012年深圳地铁的碳排放进行了预测。结果显示,2012年,深圳地铁的碳排放总量将可能增加9.32倍。客运量约为11.78—5.89亿人次,相应地,旅客人均碳排放量将增加9.36%—118.71%。Carbon emission of Shenzhen metro was analyzed on basis of the power consumption of train traction and metro station. First of all, power consumption of train traction was calculated according to the annual mileage and power consumption of train in 100km. In 2008, all trains of Shenzhen metro consumed 25. 14GW·h power. In 2009, power consumption of train traction was 26.35GW·h. And then, power consumption of metro station was analyzed according to monthly average temperature and the quantity of metro station. In 2008, all metro stations of Shenzhen metro consumedl08. 21GW·h power. In 2009, power consumption of metro station was 112.2GW·h. After this, carbon emission of Shenzhen metro was calculated according to 1kW·h power carbon emission of China southern power grid. In 2008,1 kW·h power of China southern power grid emitted 210.36g carbon. In 2009, carbon emission of 1 kW·h power was 206.21g. Accordingly, in 2008, Shenzhen metro emitted 28052. 695 tons carbon. Per-passenger consumed 0. 984kW ·h power and emitted 207. 025g carbon. In 2009, carbon emission of Shenzhen metro was 28572. 561 tons. Per-passenger consumed 1. 002kW·h power and emitted 206. 697g carbon. In the end, carbon emission of per-passenger of Shenzhen metro was compared with Shenzhen Bus, medium-bus, taxi and Hong Kong metro. In 2008, per-passenger of Shenzhen taxi emitted 450. 125g carbon and was 2. 174 times of Shenzhen metro. Carbon emission of per-passenger of Shenzhen bus and medium bus was 103. 886g and 164. 429g. Shenzhen metro was 1.99 times of bus and 1.26 times of medium-bus. Per-passenger of Hong Kong metro consumed 0. 988kW·h power and emitted 166. 752g carbon in 2008. Power consumption of per-passenger of Shenzhen metro was almost equal to Hong Kong metro. But carbon emission of per-passenger was 1.24 times of Hong Kong metro. The reason was the power used by Hong Kong metro emitted lesser carbon than China southern power grid. In 2008, 1 kW·h power of China Light ＆ Power Company and Hong Kong Electric Holdings Limited
