中文摘要： 四维城市指三维的城市空间中加入时间维度，是在时间作用下，由历史累积所呈现出的时空关系，反应了城市发展过程中的历史文脉。对四维城市的研究就是从时间的视角，以历史遗存（迹）为线索，在其空间表征的基础上，认识城市空间的形成逻辑，显示城市空间的文化特征，引导城市的保护与建设。 首先，本项目从城市空间的社会本质特征出发，首次提出四维城市的概念，并建立四维城市的理论框架；第二，探索基于时间矢量的城市空间演化规律，即长时段的山水格局、中时段的城市形态及短时段的建筑物，寻找其中的时间轨迹和空间结点；第三，构建城市历史空间的辩识方法，包括空间分辨率和语境分辨率的评价体系，基于结构、功能、物态、文脉识别的认知地图分析；第四，结合相关案例，将研究成果用于城市规划实践，为我国城市遗产保护提供理论指导和技术支撑。尤其对城市历史空间的计量和转译研究，对长期困扰在该领域的原真性与完整性问题，具有一定突破性意义。

英文摘要： For the four-dimensional city, besides the boundary of three space dimensions, it also has one time dimension. Thus a study on the four-dimensional cities will focus on the causation and consequences of space and time during urbanization process. By tracing the contextual and spatial representation of historical sites, the study is expected to learn the formative principles as well as the cultural characters of urban space so as to provide guidance for the practice of conserving design in urban construction. The study will start from defining the conception of four- dimensional cities. A first proposed theoretical framework will be established. Secondly, the study will analyze the spatial characteristics of urban evolutional law through time vectors. A comparative study on the long-term structure of landscape livable city, middle-time image of city and short-term form of building will be conducted so as to build a model of trajectory planning based on time interval. Thirdly, by using computer aided design techniques, the study will develop an identification system of historic urban spaces based on cognitive map. The category of identification system includes the resolution ratio of urban structure, function, state, and context. Finally, the theoretical knowledge shall be put into urban planning practices so as t
