生命周期视角下的建成环境对居民出行碳排放影响研究--以昆明市为例

Influence of Built Environment on Residents'Travel Carbon Emissions from the Perspective of Life Cycle--A Case Study of Kunming

城市建成环境对出行碳排放具有长期影响作用,两者关系一直以来受到学者们的广泛关注。已有研究忽视了生命周期变化带来人群影响的差异性,这可能导致错估建成环境影响程度。文章基于生命周期理论将人群分成单身期、新婚期、育儿期、教育期和向老期,利用多元线性回归探讨了建成环境对居民出行碳排放影响程度。结果表明:不同生命周期的人群出行碳排放受到建成环境影响的尺度和指标均存在一定差异性,并且这种差异性与生命周期变化存在一定的关联性。

The urban built environment has long term impact on travel carbon emissions,and the relationship between them has attracted much scholarly attention.In general,heterogeneity of residents due to the development of life cycle has been ignored in previous studies,and it may miscalculate the influence of built environment.Based on the theory of life cycle,this study which uses multiple linear regression equation discusses the effects of built environment on residents'travel carbon emissions by different stages of life cycle that is composed of single-period,newlyweds-period,parenting-period,educating children-period and ging-period.Result shows that the influence of built environment on travel carbon emission is affected by residents'stage of life cycle in terms of scales and indicators,and the differences are related to the development of residents'stage of life cycle.
