祁连山区三大内陆河近50年来出山径流特征分析
Analysis of the features of the mountainous runoff in three inland river basins of Qilian mountain during recent 50 years
摘要
Abstract
Based on the runoff data of three inland rivers from the control hydrologic stations for mountainous runoff ( Zamusi, Yingluoxia, Changmapu ) from 1956 to 2006, the numerical method, Mann -Kendall nonparametric test, Hurst index analysis methods were used to analyze the annual variation of runoff in recent 50 years. The results showed that there was marked runoff change in record series but in different years; Shiyang River had a decreasing tendency especially in the 1990s, runoff of Heihe River and Shule River were increasing, Shule River had a marked change in 1997; Hurst index analysis indicated Heihe River had an high increasing tendency , Shiyang River had an low increasing tendency.关键词
