上海市城市外围大型居住社区居民碳排放分析

The Analysis of Carbon Emission from Residents of Large Residential Communities in Outskirts of Shanghai

随着城市化的快速增长,城市外围大型居住社区成为了一种新的趋势。通过对上海市外围大型居住社区居民出行行为的调查,以居民实际出行路径为依据,对居民通勤和非通勤情况下每日的碳排放量做了具体的计算和分析。研究发现,人均通勤碳排放量与社区距离城市中心距离有一定的关系,距离越近的社区人均碳排放量越小;距离越远的社区人均碳排放量越大。但是,远距离的城市外围居住社区居民通勤交通碳排放量有可能通过建立便利的轨道交通站点得到有效降低。

With the increasing of urbanization, the large residential communities in outskirts of the city became a new tendency. Based on the investigation of the behavior patterns of residents of large residential communities in outskirts of Shanghai, in accordance with personal actual travel route, this paper calculated and analyzed the daily carbon emissions in the case of the commuting and non-commuting. The results found that there is a certain relativity between per capita commuting carbon emissions and the distance from city center to the communities. The shorter distance from city center to the communities is, the less per capita commuting carbon emissions is. The longer distance from city center to the communities is, the more per capita commuting carbon emissions is. However, the per capita commuting carbon emissions from large residential communities, which is long distance from the city center, can be reduced through establishment the convenient rail transit site.
