The results based on fractal theory show that the model parameters obtained by scaling transformation are used to simulate the flow process of the Tianxiansi Basin from 2008to 2011.The average deterministic coefficient is 0.65，and the relative error of flood volume is within 3%，respectively.The effect is good.Therefore，in the scale interval，if the scale index of the spatially sensitive parameters of Xin′anjiang River is known，the values of the spatially sensitive parameters of the reference station and the area of the basin with no data can be used to obtain the estimated values of the model parameters of the sparse data region.Hydrological simulation is performed to realize the transfer of hydrological model parameter values in areas with data to areas without data.The scaled index of model parameters can be derived by drawing aparameter basin area relationship diagram.
