Parameters’ acquisition is a key step for the distributed hydrological model when simulating a basin. Based on remote sensing technology, this article proposed a parameters acquisition method of distributed hydrological model. That is extracting the important ground objects’ information from the images to obtain some parameters of the model. This article also used the hierarchical classification principle, and introduced the extraction method of several ground objects. At last, by means of TopModel, we simulated the Xueye Reservoir, Laiwu City in Shandong Province. The experiment shows that this method can effectively improve the accuracy of model simulation.
