利用松花江,嫩江流域1951～1995年期间的气象和水文资料,采用相关分析,经验正交分析等方法,讨论了该流域洪涝发生的规律及其与流域内降水分布的关系.文章指出,江流域的水位变化有明显的阶段性,且具有全流域一致的特性,目前正处在80年代以来洪涝较严重的阶段;嫩江流域降水异常偏多对松花江洪涝的影响比第二松花江的作用要大;1998年夏季,松花江,嫩江流域出现超历史纪录特大洪水的关键原因是嫩江流域6～8月的降水距平百分率远远超过了历史上的的最大值.

With the meteorological and hydrographic data in Songhuajiang and Nenjiang valley from 1951 to 1995,using correlation analysis and empirical orthogonal analysis,the rule of the flood and relation between flood and precipitation distribution in this region are discussed.The results show that periodic change of water level is obvious in this region.Now water level is in the serious stage from 1980's.There are great relation between the water level of flood period and the precipitation.The unusual precipitation of Nenjiang valley has greater impact than that of Second Songhuajiang valley.At the summer in 1998,Songhuajiang and Nenjiang valley encountered the ghastly flood and the reason for that is the anomalous precipitation great exceeding the historic maximum.
