深圳地铁碳排放量

本文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。首先，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吨，旅客人均耗电量为0.984度，旅客人均碳排放量207.025克；2009年为碳排放量28572.561吨，旅客人均耗电量为1.002度，旅客人均碳排放量206.697克。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11.62-7.26亿人次，相应地，旅客人均碳排放量将增加10.86-77.39%。

The carbon emission analysis of Shenzhen Metro

The carbon emission of Shenzhen metro was analyzed from power of train traction and metro station. Above all, the power consumption of train traction was 25.14GW?h in 2008 and was 26.35GW?h in 2009. The power consumption of metro station was 108.21GW?h in 2008 and was 112.2GW?h in 2009. After that, the carbon emission of Shenzhen metro was calculated according to 1 kW?h carbon emission of China southern power grid. The carbon emission of Shenzhen metro was 28052.695 tons in 2008 and was 28572.561 tons in 2009. The power consumption of per-passenger was 0.984 kW?h in 2008 and was 1.002 kW?h in 2009. The carbon emission of per-passenger was 207.025g in 2008 and was 206.697g in 2009. And then, Shenzhen metro was compared with Shenzhen Bus, medium-bus, taxi and Hong Kong metro. In 2008, because the lower passenger rides, carbon emission of per-passenger of Shenzhen metro only lower than taxi(46% of taxi). It was 1.99 times of bus and was 1.26 times of medium-bus. In additional, because 1 kW?h carbon emission of power used by Hong Kong metro lower than China southern power grid, although power consumption of per-passenger of Shenzhen metro was equal to Hong Kong metro, carbon emission of per-passenger still was 1.24 times of Hong Kong metro. In the end, carbon emission of Shenzhen metro in 2012 was predicted. The results showed that, in 2012, carbon emission of Shenzhen metro would increase 9.32times. Passenger rides were 1.162-0.762billions. Accordingly, carbon emission of per-passenger would increase 10.86-77.39%.
