The Influences of the Sand-driving winds on the Silt Content of Some Tributaries in the Middle Sand-blowing Reaches of the Yellow River |
| |
| Abstract: | The climates in the middle reaches of the Yellow River is semi-arid, andthere locate Ulanbuh Desert, Kubqi Desert and Mu Us Sandy Lnnd.Inthis region, the frequent activities of the sand-driving winds have profoundeffects on the silt content of the Yellow River in many respects. In thisPaper, the characteristics of the climates in this particular area are expoun-ded. The amount of sand blown into some tributaries of the Yellow River iscaculated on the basis of field observation, and the macroscopic influencesof the sand-driving winds on the silt content of these tributaries is also dis-cussed. |
