摘　　要：本文利用文献记载建立了五代至北宋时期(中世纪温暖期)的降水等级指数,指数表明这个时期华北地区大范围降水比较多见,在百年尺度上有两次峰值,第一次出现在970s年代,第二次出现在1080s年代。降水等级的波动与黄河决溢次有数很好的相关关系,尤其是降水的峰值年代与黄河决溢的峰值年代完全匹配。因此华北地区汛期大范围强降水是当时黄河决溢的主要原因。中世纪温暖期华北地区出现了降水增加、洪涝多发,是整个时期的基本特征,而两者年代际的变化并没有完全的对应关系,但有寒冷事件记载代表冬季寒冷的年份通常夏秋汛不发生大范围降水。In this paper, the literature has established the Five Dynasties to the Northern Song Dy- nasty （Medieval Warm Period） precipitation level index, the index indicates that the large--scale pre- cipitation in northern China during the relatively common in the century scale has two peaks, first ap- peared in the 970s era, the second appearance in the 1080s. Fluctuations in precipitation levels and the Yellow River dike has a number of very good correlation between the peak years in particular, the peak years of precipitation and the Yellow River dike exact match. Therefore, a wide range of North China flood heavy rainfall, was the main reason for the Yellow River dike. Medieval Warm Period cor- responding increase in precipitation in North China emerged flood--prone is the basic feature of the whole period, both decadal changes did not fully correspond to the relationship, but there is a cold winter cold events recorded on behalf of the year is usually a wide range of summer and autumn floods do not occur precipitation.
