【Abstract】 Main research achievements in the soil erosion and sediment yield budget of watersheds in the world are summarized in this paper. The main sources of sediment yield in a drainage area and it’s main research methods are analyzed. The research progresses on the slope_channel process and linkage are introduced. The research issues about sediment storage and sediment delivery are put forward too. The advantage and disadvantage of several models are discussed. Finally, the tentative plan on soil erosion and sediment yield budget research in China is proposed.更多还原
