Abstract: To improve the physical connectivity and hydraulic relationship between rivers and lakes, describe the connectivity characteristics theoretically and systematically, the development of related connectivity ecological models is reviewed. The con nectivity characteristics are analyzed on three spatial dimensions, which are flows from upstream to downstream in the length ways ,the flood overflow in lateral, and flows exchange between surface water and groundwater in vertical respectively. The eco logical impacts of the material flow, species flow and information flow in three spatial dimensions are discussed. Based on the above analysis, considering the structures, functions and processes of ecosystem, three types flows via 4D connectivity ecological modelisproposed to summarize the connectivity mechanism of river and lake system integratedly. The parameters of connectivity ecological model and the criterion to determine the transition of different connectivity conditions areput forward. The result shows that, three types flows via 4D connectivity ecological model can be used to evaluate the connectivity status of rivers and lakes by establishing a reference system and a grading system. On the other hand, it can be used to simulate and calculate the connectivity characteristics and the ecological processes, which will promote the restoration of natural hydrological processes and the relevant ecosystem functions, improve the scientificity and reliability of water ecological restoration projects, and improve the integrity of aquatic ecosystems and ensure the service functions of ecosystems. Keywords: connectivity； material flow； species flow； information flow； ecological model
水生态修复工程的科学性和可靠性，达到改善水生态系统整体性、保障生态系统服务功能的目的。
