空间规划通过提供节能住区和促进可再生能源的利用，在减缓气候变化方面发挥着越来越重要的作用。然而，城市空间规划对城市二氧化碳排放空间格局的影响却鲜有研究。城市分区规划的变化与主要经济部门的二氧化碳排放量之间的关系尚未在小于整个城市的规模上进行调查。本研究以台北都会区为例，假设：（1）二氧化碳排放在都市内部具有空间维度，主要是由于土地使用活动和都市化的异质性;（2）空间规划的改变可以影响都市形态，并通过交通需求和能源消耗的变化影响二氧化碳排放。本研究以台北都会区为研究对象，采用降尺度分析法，估算台北都会区各行政区不同产业的二氧化碳排放量。研究结果表明：1981- 2011年台北都会区4个部门的二氧化碳排放总量随着都市计划区的增加而增加，且二氧化碳排放量的增加与各行政区的土地利用分布相关。人口密度与交通部门二氧化碳排放量呈负相关。城市交通系统的紧凑发展和规划被认为是减少人均二氧化碳排放的来源。虽然许多研究强调空间规划对应对气候变化很重要，但这项工作表明，了解空间规划和二氧化碳之间的历史联系同样有价值。
Spatial planning plays an increasingly significant role in climate change mitigation by providing energy efficient settlements and promoting the utilization of renewable energy resources. However, the effect of urban spatial planning on spatial pattern of carbon dioxide emissions in cities is rarely discussed. The relationships between the changes in urban zoning plans and carbon dioxide emissions of major economic sectors has yet to be investigated on a scale smaller than an entire city. Using the Taipei metropolitan area as a case study, this study hypothesizes that: (1) carbon dioxide emissions have a spatial dimension within the city due mainly to the heterogeneous nature of land use activities and urbanization, and (2) changes in spatial planning can influence the urban form, and consequentially affect carbon dioxide emissions through changes in traffic demand and energy consumption. A downscaling analysis approach was used to estimate carbon dioxide emissions of different sectors for each administrative district in the Taipei metropolitan area. The analytical results reveal that the total carbon dioxide emissions of the four sectors in the Taipei metropolitan area increased with the increases in the growth of urban planned zones during the period 1981–2011.The carbon dioxide emission increases were correlated with the distribution of land uses in each administrative district. A negative correlation was found between the population density and theper-capitacarbon dioxide emissions in the transportation sector. The compact development and planning of urban transit systems are believed to be the source of decreasing per-capitacarbon dioxide emissions. While many studies have emphasized that spatial planning is important addressing climate change, this work demonstrates understanding the historic links between spatial planning and carbon dioxide is equally valuable.
