Abstract:
Objective The rural landscape of the Jiangnan Canal is characterized by a synergistic symbiosis of water basin habitats, canal water conservancy and transportation, and rural settlement creation.Based on the perspective of the association and coupling of water network-canal channel-rural landscape, the study explores the types of rural landscape features and spatial coupling patterns in the Jiangnan Canal Basin.
Methods The research selects the Tiaoxi river-Canal basin in Zhejiang Province, which is closely connected to the Jiangnan Canal, as the object of study. At the river-canal basin scale, method of multi-level spatial superposition is utilized to identify associative feature zones.At the village settlement scale. At the rural community scale, through spatial maximum expectation (EM) clustering, the types of rural landscape features are classified, and the types are spatial mapped through simulation algorithms.
Results The study identifies three major landscape feature zones including West Tiaoxi River-DiTang Canal Basin, East Tiaoxi River-Jiangnan Canal Basin, and Hangzhou Hangzhou Pond-Jiaxing Canal Basin and six types of rural landscape paradigms, including canal hydraulic engineering, regional agricultural production, township community linkage, canal trade operation, water conservancy culture collection and water network habitat maintenance types. And significant regional watershed differences are explored in the perspectives of spatial proportion, layout patterns, and coupling relationships between different types of rural landscapes
Conclusion The study re-examines the dynamic adaptation mechanism and spatial association pattern of rural landscape in the process of the Jiangnan Canal""s man-made waterway system and the natural water network system evolving from passive linkage to active mutual adaption, providing references for the planning of the resilience system which accounts for the protection of the Canal historical heritage as well as the high-quality integration and development of the urban and rural areas within Canal-Basin.
