The invention discloses a flood storage and detention area flood scheduling method and system based on virtual river channel replacement gate hole discharge calculation, and relates to the technical field of flood simulation. The method comprises the following steps: constructing a main stream river channel one-dimensional hydrodynamic model of a watershed; acquiring high-temporal-spatial-resolution underlying surface data of the flood storage and detention area of the drainage basin, and constructing a two-dimensional hydrodynamic model of the flood storage and detention area; parameters of a flood inlet gate and a gate hole of a flood storage and detention area of the drainage basin are obtained, and a virtual river channel drainage model is constructed; coupling the three models to generate a flood storage and detention area flood dispatching model; and carrying out simulation calculation by adopting the flood storage and detention area flood scheduling model, and outputting a drainage scheme with optimal
