河湖水系连通是调整水土资源匹配关系、提升河湖服务功能、提高水资源调配能力、改善生态环境状况、降低洪涝灾害风险的重要手段与措施。目前河湖水系连通相关研究十分薄弱，许多实践经验也亟待总结。本文根据河湖水系连通的历史演变过程，从军事和航运、灌溉和供水、江河湖泊治理、水资源配置及水生态环境修复等五个方面，对国内外河湖水系连通工程进行了分析，总结经验。揭示河湖水系连通的发展趋势，为推进河湖水系连通研究提供参考。

Interconnected River System Network (IRSN) is an important approach for regulating the matching relationship between water and land resources, enhancing river service function, enhancing water resources allocation capacity, improving ecosystem environment, and reducing flood risks. IRSN has rarely been investigated in the literature, thus there is an urgent need to summarize the practical experiences. In this paper, based on the historical evolution process of IRSN, the IRSN practices in China and abroad were analyzed from the perspectives of military and transportation, irrigation and water supply, river management, water resources allocation, and restoration of eco-hydrological environment. The development trend of IRSN was identified, which can provide good reference for the future studies on IRSN.
