城市交通碳排放分析及实证研究

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。

Analysis and Empirical Study of the Urban Transport Carbon Emissions

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.
