Abstract: For the recent years,the erosion and sediment yield on the Loess Plateau tend to decrease obviously,as a result of the periodical reduction in precipitatior.Starting from the condition of global climatic warming in the future,this paper discusses the tendency of variation in the erosion and sediment yield on the Loess Plateau,Based on the correlation between the variations in erosion and climate in history,it has been identified that both the strong erosion and the deposition occurred during dry periods Because of the oncoming global climatic warming,the Loess Plateau will go into a wetter period,with an increasing precipitation.Consequently,the cover of vegetation will increase,leading to a reduction in erosion and sediment yield.ue to a limited environmental capacity and an over-laden population,the erosion and sediment yield will still remain at the present level

Key words: climatic warming, erosion and sediment yield, wetter period, dryer period, the Loess Plateau;
