基于额尔齐斯河流域1966年—1989年和1990年—2010年2个时间序列的降雨、径流数据,对其进行一致性修正,结果表明:径流在2个时间序列中共发生2次突变,并以此为依据对跳跃前后的径流序列进行一致性修正,对修正后的序列进行假设检验和趋势分析,结果表明修正后的序列具有较高的一致性水平。
Based on the two rainfall and runoff data from 1966 to 1989 and from 1990 to 2010 in the Irtysh River Basin, the consistency correction was made. The results show that there are two mutations in two time series, Based on this, the runoff sequences before and after jumping were uniformly modified, and the hypothesis test and trend analysis of the corrected sequences were carried out. The results show that the modified sequences have a high level of consistency.
