The Study on the Sediment Production and Transportation on the Loess Hill Regions in the Eastern Parts of Inner Mongolia

摘要

The main production layer in loess hill region of in the eastern parts of Inner Mongolia is the loess, Pisayan, and Aeolian sediment. In which the Huangpucuan watershed sediment yield modulus is loess 17,000t/(km~2 • a), Pisayan 23,000 t/(km~2 • a), Aeolian sediment 1,400 t/(km~2 • a), in the Hunhe watershed loess reaches 5,200t/(km~2 • a)—7,500 t/(km~2 • a). Overland and cleuch have the same law on the sediment yield production and transport.
