水文序列的一致性分析是水文计算中的一项重要内容 ,以黄河中游的无定河流域为例 ,运用斯波曼秩次相关检验法检验了该流域水文序列的趋势性 ,然后 ,利用有序聚类分析法推估了人类活动对序列的显著影响干扰点。结果表明 :1972年是无定河流域水文序列的突变点 ,1972年以后人类活动对该流域水文的影响更为显著。 The consistency analysis of hydrological sequences is an important part of hydrological calculation. Taking the Wudinghe watershed in the middle reaches of the Yellow River as an example, the trend of hydrological sequence in this basin is tested by using the Spolman’s rank correlation test. Then, Clustering analysis estimated the significant impact of human activity on the sequence of interference points. The results show that: 1972 is a sudden change in the hydrological sequence of the Wudinghe River Basin. After 1972, human activities have a more significant impact on the hydrology of the river basin.
