摘　　要：选择高石崖站作为孤山川流域代表站,采用年降雨量、年径流量和年输沙量序列资料,用滑动分析法分析序列的变化趋势,用传统的数理统计法检验序列的一致性,用滑动t检验、有序聚类法和Mann-Kendall检验法分析序列突变情况。结果表明:高石崖站年径流量、年输沙量序列发生了非一致性变异,突变年份为1996年,下垫面变化是孤山川流域水沙变化的主要原因。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.
