Abstract: Historical geomorphology is normally a study of the changes of landforms in the historical period.It has developed rapidly with its growing needs in the. production and construction of our country.Geologists, pedologists, by draulic engineers, archeologists and conservationists often consult historical geomorphologic knowledge.In theory, we know that the river meandering channel would migrate on the flood plain,but when did it cut off the meander neck? The gully would be elongated continually,but how many meters has it been elongatedy The piedmont would be buried by debris and sand coming down from the mountain slopes, but how many meters per 100 years? Historical geomorphology answers such kind of questions.Therefore, after researches on historical geomorphology, one would get some good ideas,which are helpful to the production and construction in our country. For example, the yellow River was not in one channel during the historical time.The present single channel form is the result of building dykes by human beings,so it must be noted,that its floods have destroyed the dykes and channged its course.And thus,in this article, the author suggests that the Yellow River might be branched into a fan-like channel system instead of one channel at the present day.For the fan-like channel system can make all the soil and water stay in the great, thirsty North China plain.
