Analysis and Research on Spatial Nodes of Historical Villages based on Spatial Syntax Theory: Cuiwei Village in Qianshan Area of Zhuhai as an Example

This research takes Cuiwei Village located in Qianshan District of Zhuhai City as an example. The village is investigated and analyzed through field research, and the street scale, spatial structure, functional characteristics of streets, internal commercial distribution forms, and functions in the Cuiwei Historic Block are studied and analyzed. Based on the convex space analysis method and the line of sight analysis method in the space syntax theory, with the help of the Depthmap software, the complex street nodes, that is, the space of the two nodes A and B analyzed. Through the establishment of a viewshed model, including the analysis of the viewport integration degree, the viewport agglomeration degree, the viewport connection value and the spatial characteristics of the historical area, the most representative traditional buildings in the village, namely the Sanwang Temple and the Weishi Mansion, are selected. =N and when the radius R=3, observe the changes of the two parameters, the integration of the visual field and the visual depth of the two historical buildings. And with the help of Baidu time machine photos in different periods to observe and record the store's changes and people's behavioural characteristics. The results show that: at the present stage, the coordination of villages is poor, people's recognition in the village space is weak, and people cannot use local perception to reflect the overall space. There are obvious sub-interfaces between the interior of the village and the outside world—good but poor global intelligibility. After an on-the-spot investigation and analysis, it can be seen that although people can walk out of Cuiwei Village, they are always in a state of confusion, and it is difficult to grasp the spatial form of the overall area. Therefore, the space syntax analysis results are consistent with the field survey results, so this research method has good reference value and reference significance in the study of village space.
