摘　　要：距今 30 0 0a以来 ,黄河改道频繁 ,通常当河床高出两侧平地 2～ 3m ,最高达 5m时 ,便会发生河流改道。30 0 0～ 15 0aBP ,黄河通常自北向南改道 ;15 0aBP至今 ,通常自南向北改道。现在黄河河床已高出两侧平地 3m ,有些地方已高出两侧平地 10m。按河流演变的自然规律 ,黄河已达到其河床演变的临界值 ,很可能会再次改道。如人工改道 。The Yellow River course has changed frequently since 3 000 aBP.Usually the course changed as its river bed was 2～3 m or 5 m higher than the surround surface.The river usually changed from north to south during the period of 3 000～150 aBP,from south to north since 150 aBP.Now the river bed is 3 m,even 10 m higher in some places than the surround surface.In the natural river succession,the Yellow River course is in its critical situation and will probably change again.If changing by human,the most ideal river course is the low land between the two raised palaeochannels of the Hanzhi River and the East Han River.
