In response to the weak integration technology of flood forecasting and scheduling in rivers,reservoirs and detention and retention basins,especially the difficulties in real-time linkage simulation facing large-scale flood scheduling decision-making,we elaborated on the process and key points of constructing an integrated forecasting and scheduling system from three as-pects:spatial topology generalization,construction of a generalized model library,and construction of a digital scheduling rule li-brary and intelligent calling.We proposed a universal forecasting model that can consider detention and retention basins based on the Great Lake routing model and hydraulic model.The simulation model method for water surface profile forecasting in reservoir areas was introduced.We also introduced the method of simulating the upstream and downstream linkage of rivers,reservoirs,and detention and retention basins through spatial topology generalization and scheduling strategy setting.We took the Three Gorges Reservoir,middle and lower reaches of rivers and lakes,and detention and retention basins in Changjiang River as the research ar-eas,explained the improvement of model construction,the construction of integrated forecasting and scheduling system,and the ap-plication of simulation scheduling technology.Based on these factors,a system scheme for joint scheduling of water engineering in the middle and lower reaches of Changjiang River has been formed.Then,by setting up a simulated flood scene,the effectiveness and rationality of the simulation were analyzed.The results can provide technical references for regions involving joint scheduling of multiple complex water projects,and provide computational tools and decision-making basis for real-time forecasting and scheduling of water projects in Changjiang River Basin and scenario deduction.
