城市化进程中，开放空间对改善城市中人与自然、公共空间的关系具有战略性意义。结合空间分析手段系统地梳理近代以来城市开放空间形态演变，在我国是一个基本的却未引起足够重视的问题。本项目以城市形态学、生态学、历史地理学等为理论基础，以包含时间维度的地理信息系统为平台，利用多时期现状图、规划图及人口、交通、土地价格等社会经济数据，对1900s至2010年间的南京城市开放空间形态及其前因后果进行研究。主要内容：1）开放空间形态整体分析；2）开放空间与聚居区交界面形态演变及动因研究；3）多尺度开放空间生态脉络演变；4）公平可达性、城市风貌与意象分析；5）架构历史地理信息数据库。研究将清晰地再现近代以来南京开放空间演变历程，形态追溯、动因分析和后果演绎将丰富相关的知识图景，探索适合于开放空间形态研究的多角度分析方法，并将形成开放和共享的历史地理信息平台，为理解和改善开放空间形态提供科学支撑。

During modern urbanization, open spaces provide significant assets in harmonizing nature and human society, citizen and public spaces. Investigating morphological changes of open spaces from the early modernization to contemporary with digital mapping and spatial analysis, is a basic issue but has received little attention hitherto in China. Based on urban morphology, ecology and historical-geography etc, this research proposal focus on open space morphology of Nanjing from 1900s to 2010. Historical maps, planning proposals, social-economical circumstance such as demographical data and traffic networks and land price will be digitalized and integrated via the Historical-GIS platform. Sub-topics include five parts: 1) the holistic analysis of open space morphology in the municipal scale; 2) the interfaces between open space and built-up area, as well as the driving forces causing changes; 3) multi-scale ecological context analysis; 4) equity mapping, urban landscape and image analysis; 5) architecture of Historical-GIS database. The exploring research will trace explicitly the morphological process of open space in Nanjing. With morphological mapping, drives analysis and consequences deduction, new insights as well as multi-perspectives and relevant approaches will take shape. Besides these, the constructing of Historical-GIS platform, will be potential catalyzer for interdisciplinary research and public-participation; therefore provide sound foundation for understanding and hence improving open space form.
