* * Mamoru Taniguchi*，Ryouji Matsunaka**，Masahiro Hirano* 最近，人们一直在努力减少对汽车的依赖，以减少二氧化碳排放。虽然“紧凑型城市”被广泛用于这一目的，但其明确的定义尚未确立。特别是，“人口密度的增加”和“城市功能布局”哪个效应更显著，目前尚不清楚。首先，本研究旨在捕捉时间序列趋势的汽车CO2排放量在日本38个城市1987年至2005年的基础上，全国人的行程调查。其次，通过回归模型分析了几种类型的“城市功能布局”的影响。阐明了各城市汽车CO2排放量仍在增加，特别是局部城市。基于统计分析，建议采用“功能性城市布局”，如走廊城市形态，以减少汽车CO2排放。
* ** *** Mamoru Taniguchi*, Ryouji Matsunaka**, Masahiro Hirano*** Recently there is an ongoing effort to reduce automobile dependency to decrease CO2 emission. Though “compact city” is widely used term for this purpose, its clear definition is not established. Especially, it is not clear that which effect is more significant, “increase of population density” or “functional urban layout”. Firstly, this study aims to catch time series trend of automobile CO2 emission in 38 Japanese cities from 1987 to 2005 based on National Person Trip Survey. Secondly, effects of several types of “functional urban layouts” are examined by the regression model. It is clarified that automobile CO2 emission is still increasing in each city, especially in local city. “Functional urban layouts”, such as the corridor urban form is recommended for less automobile CO2 emission based on statistical analysis.
