摘　　要：黄河中游地区黄土高原遭受严重侵蚀,随着治理工程实施,地区水土保持率逐年提高,生态显著改善。选取黄河中游多沙粗沙区的昕水河为研究区,利用水沙数据、无人机影像和淤地坝数据分析时间序列上的水沙变化趋势,定量计算降雨和人类活动对减沙效益的贡献率。结果表明,该地区输沙量显著减少,人类活动占主导作用,其对径流和泥沙的影响作用在2003年后大幅增强。The Loess Plateau in the middle of the Yellow River has suffered severe erosion.With the implementation of the governance project,the regional soil and water conservation rate has increased year by year,and the ecology has improved significantly.This study selected Xinshui river in the middle reaches as the research area.The use of water and sand data,drone images,and silt dam-based data analysis time sequence of water and sand changes,quantitative calculation of rainfall and human activity pairs of human activities pairs.The contribution rate of sand reduction benefits.The results show that the amount of sediment transported in this area has significantly reduced,human activities play a dominant role,and its impact on runoff and sediment has increased significantly after 2003.
