武汉市家庭碳排放的空间分布特征研究

Spatial Feature of Urban Household Carbon Emission:A Case Study of Wuhan City, China

目前国内外对家庭碳排放的研究主要集中在家庭经济属性、居民出行特征等方面,对家庭碳排放空间分布特征及规律的认识较少。本文以低碳武汉问卷调查为基础,以GIS为平台,运用空间自相关分析,探索武汉家庭碳排放的空间分布特征。结果表明,武汉市家庭碳排放存在明显的空间自相关特征,并且生活碳排放较高的家庭更容易出现在城市中心区,而日常出行碳排放较高的家庭出现在郊区的几率更高一些。最后,依据研究结果,从空间规划方面,提出旨在降低武汉居民日常家庭碳排放的策略。

As the basic unit of city, household carbon emission plays important roles in city＇s carbon emissions. However, present studies on household carbon emissions were heavily limited to socio- economic attributes and commuting characteristics, while the spatial features have largely been ignored. This research, leveraging on data from the ＂Low-carbon Wuhan＂survey in 2012, explored the spatial distribution of family carbon emissions, by spatial autocorrelation analysis in the GIS platform. The results show that household carbon emission has obvious spatial autocorrelation. The high-level and low-level carbon emission families aggregated in different areas, resulting in cold-hotspots. Moreover, families of the high-level household living carbon emission appeared more easily in the core urban area, while the high-level commuting-related carbon emission families have the higher possibility locating in the suburban area. Finally, the suggestions of spatial planning were put forward to reduce household carbon emission in Wuhan.
