史料及遗存匮乏困境下的传统产权地块判定方法研究——以辽宁省中小型历史城镇为例

Research on the Judgment Method of Traditional Property Parcels under the Lack of Historical Data and Remains through Historical Towns in Liaoning Province

产权地块是城市形态学的重要研究层级,是城镇肌理的构成要素之一。历史城镇的保护、更新与城市修补实践都与之紧密相关。国内历史城镇通常缺少产权地块层级的信息,中小型历史城镇的地块形态资料的缺乏、现状院落产权混乱、建筑遗存保护状态不完整,这些构成了国内历史城市形态的研究瓶颈。以辽宁省中小型历史城镇为研究对象,借助城市卫星图、测绘图、航拍图、实景照片信息,探索从混乱的建筑现状逆向推断传统产权地块的形态边界的工作方法,为传统城市形态的中微观特征研究提供支持。研究是针对国内历史城镇形态研究瓶颈的本土化探索,旨在对国际城市形态类型学研究进行补充和完善。

Property parcel is an important element of urban morphology and is a core factor in the urban fabric and morphology of historical towns. The preservation or renovation of historical towns and new construction near or in historical towns require basic data at the parcel level. However, parcel studies are limited in small and medium-sized historical towns in China with the lack of parcel morphology data. As such, urban morphological studies of historical cities in China have significant shortcomings. With a focus on small and medium-sized historical towns in Liaoning, this paper analyses, clarifies and determines the morphological boundaries of their traditional parcels. With the help of satellite maps, CAD mappings, aerial photos and other photos, we conducted inferential research by plan extrapolation and onsite judgment. Whilst clarifying traditional parcels, the study serves to facilitate the extraction and arrangement of data for existing urban historical remains and exploration of the meso–micro features of urban morphology. This paper presents a theoretical exploration of ways to meet the challenge of having insufficient historical documents and physical evidence of our urban heritage. We propose a method for studying local urban morphology in China, which will contribute to the study of urban typo-morphology worldwide.
