The sediment yield of the Yellow River have been reduced sharply since 2000. Based on the remote sensing information and local investigation in the sandy region of the Loess Plateau, this investigation analyzes the quantity and quality of the current terrace, the status of shrubs-herbs-arbor vegetation in 2010-2013 and the restoration effect comparing with its natural period. Their sediment reduction calculation methods and procedures for the coexistence situation of the terrace and shrubs-herbs-arbor vegetation restoration were demonstrated in this paper. Under the average rainfall condition of years, the calculation result revealed that the sediment reduction capacity of the current terrace and shrubs-herbs-arbor vegetation at their 2010-2013 level is about 1.065 billion ton in the area of above Longmen, Zhuangtou of the Beiluo River, Hejin of the Fenhe River, Xianyang of the Weihe River and Zhangjiashan of the Jinghe River, which account for 60% of its original sediment yield. ©, 2014, China Water Power Press.
