摘要: 本文以灞河下游马渡王站的实测年径流资料为基础，分析了径流的年际年内变化以及径流的变化趋势、周期和突变点。研究结果表明：灞河下游径流年际变化大，年内分配不均匀；径流序列具有显著的下降趋势；径流序列存在7年、19年和34年的周期，19年的周期最为显著；径流序列突变起始时间发生在1971年。
Abstract: This article analyses annual runoff variation characteristics, including annual, inter-annual characteristics, tendency and mutation points, based on the runoff data series at Maduwang station in the BaheRiver. The main results are: the runoff has big inter-annual variability and its annual distribution is uneven; the tendency of the runoff is significant decline; the main periods of the runoff are 7 years, 19 years and 34 years, the period of 19 year is the most significant. The mutation of the runoff observed at Maduwang station took place around 1971.
