The invention discloses a reservoir scheduling graph drawing method for coupling ensemble forecast information, and the method comprises the steps: building a runoff forecast error random simulation model based on an in-reservoir runoff forecast sequence, and generating M in-reservoir runoff sets with certain forecast precision; reducing the M in-reservoir runoff scenes into J (M>>J) representative typical scenes by adopting a synchronous back substitution reduction method, and obtaining corresponding occurrence probabilities; describing the scheduling graph by adopting key control parametersbased on the typical in-reservoir runoff situation and the occurrence probability, and establishing a scheduling graph parameter-simulation-optimization model, namely a multi-objective optimization model; and automatically optimizing the key control parameters of the scheduling graph by adopting a multi-objective optimization algorithm to obtain a Pareto solution set, performing scheme optimization on the Pareto solution
