永定河流域径流变化特征及影响因素分析
Analysis of Variation Characteristics of Runoff and Their Influencing Factors in the Yongding River Basin
摘要
Abstract
The Mann2kendall test, Pettitt test, Moving2T test, and Wavelet analysis were applied to analyze the trend, periodicit y, and mutation of annual runoff in the Yongding River Basin according to the annual runoff data at the Shixiali, Xiangshuibao, and Guanting reservoir stations from 1956 to 2003, and the influencing factors w ere also discussed from the aspects of climat e change and human activit ies. The results show ed that ( 1) the annual runoff in the Yonding River Basin decreases significant ly from 1956 to 2003, and 27( 28) is the first major period while 20( 21) is the second major period;and ( 2) the annual runoff varies abruptly in 198221983. The variation of runoff was mainly caused by human activities, such as land utilization, gate dam construction, and groundwater overexploitation. Meanw hile, climate change has also effects on the variation of runoff to some extent.关键词
