Spatial morphological traits,influencing factors and implications of typical traditional villages situated along the Jiangsu section of the Grand Canal
The Grand Canal,a testament to China's prosperity and changes for thousands of years,features traditional villages along its route as living embodiments of the rich historical culture.Examining the spatial morphology of these villages offers a profound comprehension of traditional villages,which is crucial for supporting their conservation and development ef-forts.The study focuses on 48 traditional villages situated along the Jiangsu section of the Grand Canal.Spatial syntax indicators are utilized to quantitatively characterize their spatial configurations,while hierarchical clustering techniques powered by machine learning classify the spatial patters.The findings of this study illuminate the diverse spatial patterns,distribution traits,and influencing factors of representative traditional villages along the Jiangsu section.The research findings are as follows:(1)Spatial patterns of traditional villages along the Jiang-su section encompass 6 categories:high permeability,high compactness,high recognizability,high permeability-compactness,high permeability-recognizability,and high compactness-recog-nizability,accounting for 25％,6％,10％,17％,19％,and 23％respectively.(2)In terms of spa-tial infiltration,travel potential,spatial compactness,and local space recognition,villages along the Jiangnan section of the Grand Canal(south of the Yangtze River)are superior to those along the Zhong and Li canals.Villages in Suzhou,Wuxi,Changzhou,and Zhenjiang primarily feature three types of double-high patterns.Huai'an is characterized by high compactness and high recognizability,Yangzhou by high permeability-compactness and high compactness-recog-nizability.Villages in Xuzhou and Suqian are primarily noted for their high permeability.(3)In-fluencing factors encompass natural factors(e.g.,terrain,landscape patterns),which impact vil-lage boundaries and morphological growth;subjective and social factors,actively adapted by actors;and economic and policy factors regulating rural construction.In conclusion,the Grand Canal National Park construction and world heritage protection,rural planning and construction along the Jiangsu section should clarify spatial boundaries,emphasize village characteristics,and enhance transportation efficiency.This will safeguard Grand Canal's historical culture,fos-ter sustainable rural development and harmony between humans and nature.
