摘要

According to the observation data, the characteristics and changing tendency of annual rainfall. runoff and sediment was analyzed systematically. At the same time, the temporal-spatial course of the rainstorm and correspondence sediment-runoff relations were analyzed too. The results showed that: (1) Annual rainfall, runoff and sediment distributed unevenly and the amount of runoff and sediment declined as a whole; (2) The storm centre and covering area was stochastic in the valley. All that resulted in complicated runoff and sediment process; (3) When the streamflow was slow. with the runoff increasing, the sediment concentration would increase too. But. when streamflow reaches a certain value. sediment content tends to a constant. All these results would provide scientific reference in valley fathering and programming.
