基于不同出行方式的城市微观主体碳排放研究

从城市微观主体的角度出发,通过构建城市微观主体碳排放评测模型,探讨了城市微观主体土地利用模式对碳排放的影响。以南京市某单位为例,采用交通周转量与连续逼近法,对研究单位园区间流通带来的碳排放进行了评测。结果表明,交通方式的选择对碳排放量的影响较显著,不同交通方式的碳排放量排序为:城市公交<综合交通<单位通勤<私人轿车。

Research of Urban Micro Subject Carbon Emission Based on Various Travel Mode

This paper established the carbon emission evaluation model of the urban micro subject,and discussed the effect of carbon emission by the land-use pattern of urban micro subject from the view of urban micro subject.In the case study of one unit in Nanjing,with the aid of traffic turnover and the continuous approximation,the evaluation model was applied to calculate the carbon emission of the circulation between areas in the urban micro subject.The results showed that the selection on urban traffic mode had significant effect on carbon emission.By the comparison of the four different kinds of traffic situations,the carbon emission order of rank increase was the urban public traffic
