| 摘 要： | 以大清河水系紫荆关流域和阜平流域1956-2005年的暴雨洪水资料为基础,利用Mann-Kendall秩次相关检验法研究了流域内产汇流特性的变化规律及其影响因素.结果表明:次洪量和径流系数呈下降趋势,洪峰滞时和汇流单位线峰现时间呈上升趋势.降水量的变化对大清河流域的产汇流规律有直接的影响,但下垫面的变化在一定程度上影响了流域的产汇流规律,引起产汇流特性的变化.

| Abstract: | To study the trend of runoff generation and convergence characteristics and the influencing factors,Zijingguan and Fuping sub-watersheds are selected.Mann-Kendall Rank Correlation Test is used to analyze the storm-runoff data during 1956-2005 in the two sub-watersheds.The results show that runoff volume and coefficients have a decreasing trend,and lag time of peak flow and time of peak are increasing.The decrease in precipitation has a direct effect on runoff generation and convergence,but the underlying su... |
