水-运-村关联耦合视角下江南运河流域乡村景观特征研究——以浙江苕溪-运河流域为例

Research on the Rural Landscape Characteristics in Jiangnan Canal Basin from the Perspective of Water Network-Canal Channel-Rural Landscape Association Coupling: The Case of Tiaoxi River-Canal Basin

  • 摘要: 【目的】江南运河乡村景观具有水系流域生境、运河水利漕运与乡村聚落营造多系统协同共生的特质。研究基于水-运-村耦合互动的视角,探讨江南运河乡村景观的特征类型及空间关联机制。【方法】以浙江苕溪-运河流域为研究对象,在流域尺度,通过多层级要素空间叠加,划分流域乡村景观关联特征分区;在乡村聚落尺度,通过空间最大期望聚类分析乡村景观特征类型;通过空间模拟算法进行乡村景观类型的空间映射。【结果】研究识取出西苕溪-頔塘运河流域、东苕溪-江南运河流域及杭州塘-杭嘉运河流域三大景观特征分区及运河水工营造型、地域农业生产型、乡镇聚落联动型、漕运商贸经营型、水利文化汇集与水网生境维育型六类乡村景观类型;并发现流域乡村聚落分布密度、空间布局模式及水-运-村耦合关联强度存在明显的空间分异。【结论】研究厘清江南运河人工航道体系与自然水网体系从被动联系到主动互适的过程中,流域乡村景观的动态适应机理及空间关联模式,为大运河文化遗产保护与流域城乡高质量融合发展的韧性规划提供参考。

     

    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.
