道路交通设施便利度对家庭日常交通出行碳排放的影响——以武汉市为例

The Effect of Traffic Facilities Accessibility on Household Commuting Caused Carbon Emission:A Case Study of Wuhan City, China

以武汉为例,结合问卷调查和基础地理空间数据,计算样本家庭日常交通出行碳排放量。然后分析交通设施便利度与家庭日常交通出行碳排放的关系,并分析社会经济属性的影响。结果表明:全市层面,公交线路条数越多,交通出行碳排放越低;考虑社会经济因素影响,公交线路条数、道路交叉点越多,交通出行碳排放越低;反之亦然。考虑到武汉市多中心空间结构,分区层面交通设施便利度与碳排放呈现不同结果。最后提出低碳城市空间规划相关策略。

The paper, taking Wuhan as an example, first calculates the carbon emission of household daily travel based on questionnaire survey and some fundamental spatial data, then analyzes the relationship between traffic facilities accessibilities and carbon emission, and finally explores the influence of socio-economic factors. The results show that at the city level the number of bus route has significant correlation with family commuting carbon emission. If considering socio- economic factors including household income, education level, and the private car ownership, the number of the road crossing within 1 000 meters a/so bear correlation with family commuting carbon emission. In the district level, the results are distinct when considering the unique polycentric spatial structure of Wuhan city. Finally, the paper puts forward several suggestions on low carbon community planning.
