住区周边设施可达性对居民人均交通能耗的影响——以我国286个地级以上城市为例的实证研究

THE IMPACT OF AMENITY ACCESSIBILITY AROUND NEIGHBORHOOD ON HOUSEHOLD PER CAPITA TRANSPORTATION ENERGY CONSUMPTION:AN EMPIRICAL STUDY BASED ON 286 CITIES AT THE PREFECTURAL LEVEL AND ABOVE IN CHINA

在全球气候变化和化石能源危机的双重背景下,低碳城市相关理论逐渐成为学术界的研究热点,如何通过形态设计手段降低居民人均交通能耗是广大城市规划学者面对的一个重点课题。相对于微观领域丰富的研究成果,宏观层面城市空间形态与居民人均交通能耗的关系研究数量较少,且多以欧美城市为例,涉及的空间维度一般仅限于人口密度,对设施可达性、路网形态等城市空间形态的其他维度关注不够。本文尝试采用在线地图兴趣点(POI)数据,计算我国286个地级以上城市住区周边各类设施的可达性指标,继而探索宏观城市层面设施可达性与居民人均交通能耗之间的关系,为相关的低碳城市规划工作提出针对性建议。

The low-carbon city theory has gained attention of the research community worldwide due to global climatic change and the impending energy crisis.Cutting down household per capita transportation energy consumption has become a major issue,especially through morphology design method.Micro-level studies have yielded abundant accomplishments,yet the relationship between macro-level urban spatial morphology and household per capita transportation energy consumption has not been revealed.Moreover,other dimensions except density,such as amenity diversity and road network have been ignored in related morphology study.Amenity diversity indexes of 286 cities at the prefectural level and above in China are first estimated in this study based on POI(point of interest) data derived from online maps.The relationship between household per capita transportation energy consumption and amenity diversity is then investigated,and responding suggestions are given then.
