【摘要】 针对金沙江李庄站洪水特性进行汛期分期计算。从优化设计角度出发,提出最小汛期平均设计流量法,对根据水文特征值统计法、矢量统计法、概率变点分析法和成因分析法等得到的分期结果进行评价和综合分析,划分李庄站汛期。基于提出的方法和利于汛末蓄水的原则,可确定李庄站主汛期为7月1日～8月25日。最后,用Cunderlik法验证分期结果的合理性。更多还原

【Abstract】 This paper analyzes and evaluates flood seasonality for the Lizhuang hydrological station on the Jinsha River.A method of mean design discharge is proposed for evaluation of the results by several other methods,such as the change point method,and after this evaluation is done,a segmentation pattern of flood seasonality can be determined.Results show that the main flood season of this station is from 1st July to 25th August if the reservoir refill in after-flood season is considered.Cunderlik method is used to verify the results.更多还原
