Based on the data of annual average sediment transport modulus that 4 mountain river hydrological stations of Liuchong river, Shancha river, Chishui river, and Yeji river,monitored in Bijie region of Guizhou Province, and land use structure of these rivers basin, the BP artificial neural network model is set up.
According to proportion of land use structure of Bijie region, the model is applied to simulate , annual average sediment transport modulus of the whole region's rivers are obtained which is 628.47 t/km~2·a.
