摘　　要：大运河长期参与并影响沿线人居环境建设活动,由此衍生的水利枢纽工程影响着区域生态安全的维持。文中以大运河关键水利枢纽工程区域——四女寺枢纽区域为研究对象,基于2023年土地利用数据,通过形态学空间格局分析、景观连通性评价和最小累积阻力模型,对区域蓝绿基础设施数据进行收集、分析,结果共识别出16个生态源地、15条重点潜在生态廊道与105条一般潜在生态廊道;构建“一核两心,三带四轴,多节点,多廊道”的区域生态安全格局;最后,基于区域上位规划与景观空间特点提出生态安全格局优化建议,即蓝绿整合的韧性优化、多样保护的体系优化和突破边界的协同优化。研究结果可为大运河枢纽区域文化遗产保护和生态环境保护修复提供循证依据,并为国土空间规划与生态文明建设提供参考。The Grand Canal has long been affected by the construction of human settlements,and the resulting water conservancy projects have affected the maintenance of regional ecological security.The paper takes Sinvsi hub region,the vital water conservancy hub project area of the Grand Canal,as the research object,to collect and analyze the regional blue-green infrastructure data based on the land data in 2023 through morphological spatial pattern analysis,landscape connectivity evaluation and minimum cumulative resistance model.In the region,16 ecological sources,15 key potential ecological corridors and 105 general potential ecological corridors are identified.The regional ecological security pattern of'one core,two centers,three belts,four axes,and multiple nodes and corridors'is constructed.The paper puts forward suggestions for optimizing the ecological security pattern based on the regional master planning and landscape spatial characteristics,i.e.,enhancing ecological resilience through blue-green integration,establishing a diverse protection system,and breaking down administrative boundaries for optimal management.The relevant results can provide an evidence base for the protection of cultural heritage and eco-environment protection and restoration in the Grand Canal hub area,and provide references for land spatial planning and ecological civilization.
