摘要
城市经济发展使得城市交通迅速发展,同时也造成了能源消耗过多、排放污染加剧。文章构建数学模型对城市交通子系统碳排放进行分析,并以西安市为例进行实证分析。结果表明,城市私人载客汽车和道路运输营运部门是主要交通碳排放源,占总排放的67%以上,并且有序发展私人交通、改变交通需求结构、提高能源利用率能有效降低城市交通碳排放。
City economic development leads to rapid development of urban transport, and also brings excessive energy consumption and pollution. The article constructs a mathematical model of the urban transport subsystem carbon analysis and takes Xi'an as an empirical example. The results show that the urban private passenger automobile and road transport operations department is a source of major transport carbon emissions, more than 67% of total emissions, and orderly development of private transport, to change the structure of the traffic demand, improve energy efficiency to reduce urban transport carbon emissions.
