在中国古代都城规划史上，北魏平城具有承前启后的重要地位。目前，关于北魏平城规划设计的研究相对薄弱，亟待解决其空间布局和规划设计难题。本文在文献和考古的基础上，引入大地空间作为新材料，运用古都规画方法进行系统研究，探索还原平城格局以及规划设计的新路径。北魏平城规画研究对理解文明建构、古都规划研究、规画理论发展都有重要的学术价值。 北魏平城规画研究，围绕探索复原平城格局、还原规划形制的生成过程与逻辑、总结规划方法与挖掘历史地位三大核心问题，建立“文献梳理—空间分析—规划还原—规划方法—发展演变”的技术路径，从多学科角度探索北魏平城的空间格局与规划方法。第一，探索复原平城格局：基于文献总结出道武帝奠定框架、明元帝完善城郭格局、太武帝到献文帝增拓充实、孝文帝汉化改造四个时期。中原汉人士族、宗教力量、鲜卑军臣贵族与祭祀女巫都参与其中，明确了北魏平城营建的京畿和都城两大空间层次，厘清了规划建设尺度。将文献、考古与大地空间相结合，建构GIS空间分析平台，复原平城历史地理环境，考证平城人居关键点位置，以此探索复原平城格局，夯实研究基础。第二，还原规划形制的生成过程与逻辑：结合历史情景，复原选址、规划和营建过程。北魏平城规划有两大特征，一是从“军事边城”向“文化都城”的转变，北魏参照中原制定文化礼仪制度，制定区域规划。二是从“胡汉杂糅”向“中原正统”的转变，动态性地还原不同时期的平城形制与关键点经营，分析空间的形成逻辑和变化机制。第三，总结规划方法与价值：建构北魏平城规划方法，提炼平城规划设计特征。从规划史的角度，分析北魏平城对中古时期其他都城的影响，发掘其历史地位和价值。 研究发现，“规画”理论探索了平城空间格局和规划设计难题，并在区域设计上对“规画”理论有所发展，挖掘出北魏平城在都城规划史上承上启下的重要价值。

Capital city Pingcheng in Northern Wei Dynasty has played a significant role as a link between the past and the future in the ancient capital planning history of China. However, the studies on Pingcheng’s planning and design are relatively weak, because there are limitations on the studies that rely only on literature and archeology materials. Therefore, the new method is needed urgently to solve this problem. Based on study of literature and archaeology, this paper has presented terrain as a new study material, and conducted the systematic study by using “Gui Hua”(method of planning and design). “Gui Hua” is the new way to explore the restoring of Pingcheng’s framework as well as planning and design. The study has important academic value in understanding the construction of civilization, comprehending the evolution of ancient capitals and developing the sciences of “Gui Hua”. The study focuses on the three core issues, and establishes the technical route of “literature reviewing - space analyzing - planning restoring - planning methods - development and evolution”, in order to research the spatial framework and planning methods of Northern Wei Pingcheng from multidisciplinary perspectives. First, explore the restoration of space pattern. Filter the core literature, and based on above literature, sum up the four key periods, two major space hierarchical structures and the representatives of participants on the Northern Wei Pingcheng construction, therefore, clarify the planning and construction scale. Then, combine literature and archeology with the terrain space, set up the GIS space analysis platform, restore Pingcheng’s historical and geographical environment, verify the locations of the key points for human settlements, therefore, explore the restoring of the Pingcheng’s spatial framework, and so consolidate the research basis. Second, analyze the processes and logic of the planning: restore the historical scenarios, recover the locations, planning and construction process. The planning of Northern Wei Pingcheng has two characteristics; one is the change from a local military border city to a national cultural capital city. It rehabilitates the framework and planning method for Pingcheng County in Han Dynasty as the military human settlements. Northern Wei Dynasty draws the cultural etiquette system, and reconstructs the capital city from the basis of Pingcheng County, and so determines space range of outer city and the regional planning of the capital city. The other is the change from “a mixture of Hu and Han peoples” to “the legitimacy of the Central Plains”. It dynamically restores the system forms of Pingcheng city and key points' management; analyze the logical basis and changing mechanism of the space, in order to clarify the factors of Nomadism, Central Plains and Buddhism in Pingcheng system. Third, summarize the planning methods and values: establish the planning methods for Northern Wei Pingcheng, refines its planning features. From the perspective of planning history, it analyzes Pingcheng's influences on other capital cities in medieval times, and so that explores its historical status and values. It is concluded by the study that the theory of “Gui Hua” explores the planning and design problems of Pingcheng. This study develops the theory of “Gui Hua” in regional design. The Northern Wei Dynasty actually has participated in the evolution of China ancient capitals, and the Northern Wei Pingcheng was a transition and a significant part in the planning history of capitals.
