The invention discloses a loess plateau distributed flood simulation method for spatio-temporal differentiation of runoff production modes, and belongs to the technical field of model establishment methods. Comprising the steps of constructing a runoff production mode space-time differentiation recognition technical framework, perfecting a plant interception module, an infiltration module, an evapotranspiration module and a silt dam/terrace module, coupling a grid water drop confluence method and deep learning confluence calculation, and perfecting a model by combining a variable parameter theory and experience. On the basis of the influence mechanism of the changing environment on the rainstorm runoff production and confluence process, the space-time analysis characteristics of the loess plateau runoff production mode in the changing environment are further disclosed, the deep learning theory is combined, a distributed flood simulation model coupling runoff production mode space-time differentiation and the
