Sustainable Renewal of Spontaneous Spatial Characteristics of a Historical–Cultural District: A Case Study of Tanhualin, Wuhan, China

Abstract

Based on a fixed-point survey of spontaneous space in the Tanhualin area of Wuhan, China, spontaneous space samples were obtained. The spatial typology method was used to summarize and compare the morphological and functional characteristics of the samples, and the space was divided into 10 types and seven functions. Through quantitative statistical analysis of the relationship between different spontaneous space forms and their spatial functions, it was found that residents’ behavior in daily life has a significant effect on spontaneous space renewal and district renewal. Based on the study of the spontaneous space of the Tanhualin historical–cultural district, this study determined the status quo of the space renewal and development of the district and put forward corresponding protection and renewal strategies. Finally, it provides a theoretical basis for the sustainable renewal and coordinated development of historical–cultural districts.

Research on Factors Influencing the Style of Chinese Historic Districts Based on the Mask R-CNN Deep Learning Model

“…Tanhualin historic and cultural district is situated in Wuchang District [15,25], Wuhan City, Hubei Province (Figure 2). As a significant historic and cultural district in Wuhan City, it embodies the coexistence and mutual influence of various cultures.…”

“…It emanates a rich humanistic ambiance with local distinctiveness. However, with the rapid pace of urbanization and continuous improvement of urban functions in recent years [25], the Tanhualin Historic and Cultural District (Figure 2) underwent renovation and reconstruction in 2004 in line with urban development. Throughout the whole process, commerce served as the core aspect, maintaining the continuity of the main district interface of the historic and cultural districts to a certain extent.…”

“…Commercial canopies are primarily installed above shop entrances, offering a significant overhang to provide more commercial space and to meet basic wind and rain protection requirements. However, due to the different depths and materials used for each store's canopies, they take up a certain portion of shared district space [25], affecting the overall coherence of the district and lacking a sense of order. Reasons for the formation of spontaneous commercial spaces include the following: The formation of spontaneous commercial spaces can be attributed to two main factors: residents seeking to capitalize on the commercial potential of their spaces, and merchants striving to expand their business areas and enhance the economic value of their commercial spaces.…”

Digital Twin Research on Masonry–Timber Architectural Heritage Pathology Cracks Using 3D Laser Scanning and Deep Learning Model

“…Additionally, the Western Church introduced innovative educational approaches and architectural styles to Wuhan. Notably, Tanhualin Historic Street (Figure 1c) stands out as an ancient neighborhood with the richest history and cultural heritage in Wuhan [20,21]. This area is recognized as the birthplace of China's first library and served as a pivotal hub for modern education in the country.…”

“…The research strategy involves utilizing the high-precision and extensive geometric information of architectural heritage images obtained through 3D laser scanning to detect, categorize, identify, and calculate pathology crack areas in architectural heritage. James Jackson Gymnasium, located in the Tanhualin Historic District [20] of Wuchang District, Wuhan City, China, is chosen as the study subject to validate the proposed methods for regional detection, categorization, identification, and calculation of architectural heritage 3D laser scanning based on pathology cracks technology and a deep learning model, as well as the resulting architectural heritage detection and restoration system. The outcomes of this research will not only offer robust technical support for the conservation and restoration of architectural heritage but also hold significance for the advancement of scientific knowledge in the field of architectural preservation and restoration.…”
