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。
Under the dual background of global climate change and fossil energy crisis, theories related to low-carbon cities have gradually become the research hotspot in academia. How to reduce the per capita energy consumption of transportation by means of morphological design is one of the key topics that urban planning scholars face. Relative to the rich research results in the micro area, the research on the relationship between urban spatial form at macro level and per capita energy consumption of residents is relatively small. In the case of European and American cities, the spatial dimension involved is generally limited to the population density, , Other forms of urban space morphology such as road network attention is not enough. This paper attempts to use online map point of interest (POI) data to calculate the reachability index of various facilities around 286 prefecture-level cities in China, and then explore the relationship between facility reachability at the macro-city level and per capita energy consumption of residents Relationship, for the relevant low-carbon city planning put forward targeted suggestions.
