Study on spatial form evolution of traditional villages in Jiuguan under the influence of historic transportation network.

Traditional villages are China's cultural heritage resources; they carry rich historical and cultural information and have important historical significance and cultural value. Studying their spatial forms can suggest new ideas for the protection of traditional villages. The spatial configuration of traditional villages is shaped by a complex interplay of natural geography, socio-economic factors, transportation infrastructure, and essential facilities. Various developmental scenarios lead to diverse spatial development patterns, each demonstrating unique dynamic characteristics throughout its evolution. This article focuses on the exploration of the spatial morphology of Jiuguan Village, located along the Jingxing Ancient Post Road. By using kernel density analysis, space syntax, spatial form index, and so on, the spatial form of Jiuguan Village was studied from three aspects: public facilities clustering degree, road system, and spatial form index. Through a hierarchical approach involving points, lines, and planes, our study unveils the multifaceted influence of transportation factors on the village's historical development and its dynamic adaptive attributes within the context of traditional village spatial morphology. The results indicated that the location advantage of traffic is the driving force behind land expansion. Secondly, the areas with high traffic accessibility tend to be public spaces in villages. Third, the change in the transportation market will lead to a change in village land use functions. Finally, the renewal of transportation modes will change the spatial scale of the village. This research offers a deeper comprehension of the historical context surrounding traditional villages and provides a scientifically guided framework for heritage preservation and sustainable village development.
