渭河陕西段径流系列的一致性分析

水文资料是工程设计的基础资料，其资料的一致性直接影响工程设计结果的合理性。本文采用渭河陕西段林家村，咸阳，华县三站1951—2010年的年径流资料，定性分析、定量检验了其序列的一致性。结果表明：①径流序列的趋势、突变及参数等的变化并不足以表明其一致性的改变，需要进一步的检验；②通过定量检验表明：1969—1971年的突变并未通过显著性为0．05的一致性检验，而1991—1994年的突变却通过了显著性为0．05的一致性检验，说明渭河陕西段径流序列的一致性改变发生在1991—1994年间。

Consistency analysis of runoff series in Shaanxi section of Weihe River

Hydrological data is the basis of engineering design and the consistency of its data directly in- fluences the rationality of design results. The paper used the runoff data of the three station of Linjiacun, Xianyang and Huaxian in Weihe river of Shaanxi section from 1951 to 2010 to qualitatively analyzed and inspected the consistency of the sequence. By analyzing and contrast we concluded that the change of the trend, mutation and parameters of runoff series is not enough to show its change of consistency, need fur- ther inspection; the quantitative test showed that the mutation from 1969 to 1971 did not pass the consis- tency check of significance being 0.05, and the mutation in 1991 - 1994 is passed the significant consis- tency check for 0.05, witch shows that the change of the consistency of runoff series Shaanxi section of Weihe river took place during 1991 to 1994.
