摘要: 文章以鄱阳湖流域6个水文控制站1955-2007年的逐日平均流量数据为基础,分析了该流域年径流量的年际变化及年内变化特征,并采用Mann-Kendall非参数检验法(MK检验)对其时间序列的变化趋势进行分析。结果表明各站径流量年际变化较大;年内径流主要集中在4~7月,与降水量的年内分配保持一致;1950s以来流域年径流量呈不明显的上升趋势。

Abstract: Based on the daily runoff data of 6 control stations in Lake Poyang basin from 1955~2007, the feature and trends of annual and seasonal runoff were analyzed by using Mann-Kendall test. The results showed that:Monthly runoff of the basin was mostly concentrated between April and July, which was consistent with precipitation;annual runoff has increased slightly since 1950s.
