| 摘 要： | 基于黄河内蒙古段系列历史冰情资料,利用小波分析方法对冰期气温、冰期径流、流凌日期、封河日期、开河日期进行了多时间尺度分析。结果表明:巴彦高勒、三湖河口、头道拐三站的冰期气温总体呈上升的变化规律,并且三站的冰期气温变化趋势一致,黄河内蒙古段冰期气温存在15 a左右的周期;实测径流在分析序列中不存在显著周期;三站流凌日期和封河日期整体上推迟,开河日期提前,封冻时间缩短;流凌日期存在12 a左右的周期,封河日期和开河日期不存在显著强周期。 |

| Abstract: | Based on the series history of ice information in Inner Mongolia section of the Yellow River and using wavelet method the paper carried out multiple time scale analysis on glacial temperatures,glacial runoff,ice-flow date,freeze-up date and break-up date and The results show that ice age temperature of the stations of Bayangaole,Sanhuhekou and Toudaoguai is increasing and the trend of ice age temperature of the three stations is consistency.There is an ice temperature cycle of about 15 years in the section.There is no significant period in the sequence of measured runoff.Three stations’ ice-flow date and the date freeze-up/break-up overall delay,open river date is advanced and frozen time is shorter.There is about 12-year cycle of ice-flow,freeze-up/break-up date and open rive date has no significant strong cycle. |
