摘要: 【目的】作为主要的水运基础设施,运河通过人工建设连接不同的水域或流域,从而满足航运、引水、灌溉等功能性要求。随着绿色化水运基础设施的发展,运河航道建设过程需要更多地考虑生态环境因素,以最小化工程建设对生态系统的影响为目标,促进生态保护与景观利用。【方法】以国家级大型运河航道实践——“引江济淮”工程为例,基于GIS空间数据处理与叠图分析,利用地形、气候、植被、人文景观资源等信息,对运河沿线的空间信息进行叠加分析和可视化展示。【结果】依托运河开挖后形成的线性空间,提出以恢复生态廊道连通性和廊道景观在地化为双重策略,形成七大主题展示的景观分区,选择其中的4个核心节点控制线性空间变化与景观叙事节奏,从而形成完整的运河生态-人文景观建设路径。【结论】通过全面分析运河生态景观的建设要素,充分融合运河的生态修复与文化属性,探索自然与人文融合的运河航道生态景观构建策略,为生态文明背景下建设绿色生态水运基础设施提供景观规划方法支持。Abstract: [Objective] As a major water transportation infrastructure, canals connect different waters or basins through artificial construction, so as to meet the functional requirements of navigation, water diversion and irrigation. In view of the development requirements of greening water transport infrastructure, more consideration needs to be given to ecological factors during the construction of canals and waterways, with a view to minimizing the impact of construction on the ecosystem, and promoting ecological conservation and landscape utilization.[Methods] Taking the national large-scale canal waterway practice-Yangtzeto-Huaihe Water Diversion Project as an example, this research, based on GIS spatial data processing and map overplay analysis, achieves the overplay analysis and visual presentation of the spatial information along the canal by virtue of relevant information on topography, climate, vegetation and humanistic landscape resources.[Results] Relying on the linear space of the canal, it is proposed to restore ecological connectivity and localization of landscape as a dual strategy to form 7 thematic display landscape zones, and choose 4 core nodes to control the linear spatial changes and landscape narrative section, thus forming a complete ecological and humanistic landscape construction path of the canal.[Conclusion] By comprehensively analyzing the construction elements of canal ecological landscape, and fully integrating the ecological restoration and cultural attributes of the canal, this research explores the strategy for constructing ecological landscape of canal waterway based on the integration of nature and humanity, so as to provide the support of landscape planning method for the construction of green ecological water transport infrastructure in the context of ecological civilization.
