LIU Jian-jun;ZHAO Li-xia;TIAN Wen-jun;XING Xiao-li;  
The Gaoshiya station is chosen as the representative station of the Gushanchuan river basin. Based on data sequences of annual precipitation, annual runoff and annual sediment runoff, the paper analyzes the change trend of the sequences by using the moving analysis method, the consistency of the sequences by using mathematical statistics method, and the mutation of the sequences by using the moving t test, order cluster method and Mann-Kendall test method. The results show that the non-coincident changes occurred in sequences of annual runoff and annual sediment runoff, the mutation year was 1996, the change of underlying surface is the main cause for the water-sediment change of Gushanchuan river basin.
