【Abstract】 Based on a series of data of the suspended load discharge measured at He-jin station in Fen River (1934-1987), Shi Xia-li station in Yong-din Rivet (1950-1988)and Luan-xian station in Luan River (1930-1988), this paper analyses theproducing-sediment characteristic and the Changing tendency of the annual sediment yield inthe rivers in both Jin and Ji provinces. In addition to this, it studies the innuence of the twofactors of the climate and human being action on the annual sediment yield.更多还原
