A method for continuous routing forecasting and operation of a reservoir group under influence of river fragmentation includes: decomposing and quantitatively characterizing a physical structure of a cascade reservoir group system based on an upstream-downstream hydraulic connection and a river channel composition feature, thereby decomposing a fragmented long river system into a river-reservoir system including water channel-reservoir-water channel basic units; generalizing an upstream-downstream relationship of each constituent unit in the system, quantifying a wave characteristic, and establishing upstream and downstream flood routing process equations; and extracting and quantifying an operation rule based on a historical reservoir operation scheme of the constituent unit, enabling a dynamic coupled feedback computation between an operation process and flood routing under different operation modes, and connecting the constituent units sequentially to complete continuous routing of the fragmented long river system.
