Research on heritage characteristics based on railway architectural heritage database in Jinzhou section of the Peking–Mukden Railway

This research interprets the background of Jinzhou section of the Peking–Mukden Railway, and puts forward 65 heritages as cases based on the scope definition and investigation. After the data collection, processing, and visualization, the database composed of 9 sub-databases, with B/S architecture mode, is constructed based on SQL server platform. The ArcGIS tool is used to analyze the distribution of the heritages, including spatial distribution characteristics, spatial agglomeration, and spatial equilibrium. "Image and model information database" and "text attribute information database" is used to analyze the architectural ontology features. The conclusions are drawn as follows: 1) The integral distribution has the characteristics of "cohesion", while the 5 medium types of heritages show obvious and different directions. 2) The overall pattern of spatial agglomeration is characterized by high cohesion with a single high agglomeration point as the core. The low agglomeration area shows a point-line-point pattern. 3) The integral heritages and three main types of buildings differ in distribution, and the equilibrium is low. The architectural ontology analysis shows that the image information can be used as the basis for ontology characteristics analysis, architectural form and style judgment, and architectural functional space analysis.
