The railway architectural heritage in Jilin Province, as a significant component of Northeast China’s modern railway network, demonstrates how construction techniques, cultural integration, and social transformation have evolved throughout different historical periods. In this study, we conducted a systematic survey of 474 railway heritage buildings along the province’s main line. In order to quantitatively classify the spatiotemporal distribution characteristics of the heritage sites, we used five key Geographic Information System (GIS) methods—kernel density estimation, nearest neighbour index, spatial autocorrelation, standard deviational ellipses, and mean centre analysis—along with information entropy, relative richness, and the Bray–Curtis dissimilarity index. We continued our binary logistic regression using four prerequisite parameters—location, structure, architecture, and function—which contribute to the prerequisite, fundamental, and driving factors of architectural heritage. We concluded that local culture shapes geopolitics, population migration triggers economic conservation, and design trends carry ideology. These three factors intertwine to influence architecture and spatial patterns. Compared with previous studies, this research fills the gap concerning the architectural characteristics of towns at various lower-and mid-level stations, as well as the construction activities during the affiliated land period. This study provides a systematic framework for analysing railway heritage corridors and supports their sustainable conservation and reuse.

Residential architectural heritage in Jilin Province, particularly along the Chinese Eastern and South Manchuria Railways, represents the most abundant and widespread form of heritage in the region. This study investigates the distinctive features of these heritage buildings, which are often overlooked due to their technological simplicity, ubiquity, and atypical nature. We analyzed 28 floor plans of residential buildings from the Russian and Japanese colonial periods using GIS technology, space syntax, and Z-score normalization. The findings reveal that (1) Russian elite housing layouts are complex and circular, while Japanese layouts consist of multiple branching combinations; Russian common housing typically has single-node, multi-branch layouts, whereas Japanese housing features multi-node, fewer-branch designs; (2) Russian houses prioritize warmth and privacy, with enclosed layouts that emphasize defensiveness, while Japanese houses focus on space efficiency, rational movement, and multifunctional design, with open layouts highlighting spatial integration and functional differentiation; (3) cultural differences are reflected in factors such as the historical rivalry between Russian and Japanese powers, natural environments, family structures, and standardized construction techniques. This study offers new insights into the cultural characteristics and historical context of Jilin Province’s railway residential heritage and supports its protection and future research.
