Jinsha river is a main sediment source in the upper reaches of the Yangzi river.Through statistical analysis to water and sediment data of major hydrological control station in Jinsha river basin
the sediment transport characteristics of the basin which include sediment sources and distribution
annual variation and annual distribution of sediment discharge
the relationship between runoff and sediment discharge
and the genesis of sediment are discussed.It provides a scientific basis for the rule of soil eorsion and sediment transportation researching
and soil and water resources reasonable developing and utilizing in Jinsha river basin.
