应用文献［１］关于不同地貌类型及不同水保措施条件下黄河干支流中泥沙粒径分布的研究结果，可以对相应条件下的减沙效益进行有效的分析。利用文献［１］模型，本文不仅探讨了在给定地貌类型条件下各类水保措施实施前后流域汇入黄河干支流的泥沙总量的变化，而且还在扣除降雨变化的影响之后，预测了各类组合条件下非均匀泥沙中减沙效果最佳的粒径级和相应粒径级泥沙的减沙量，预测结果得到了黄河干支流各站所有实测资料的验证。文中还简要讨论了人类活动（主要是开矿）对减沙效益的影响。
Application [1] on different types of geomorphology and different measures of soil and water conservation in the Yellow River tributaries of the sediment particle size distribution of the results of the study, the conditions under which the effectiveness of sediment reduction can be effectively analyzed. Based on the literature [1], this paper not only explored the changes of total sediment inflows into the mainstream of the Yellow River before and after the implementation of various types of water conservation measures under a given landform type, but also deducted the effects of rainfall changes. The sediment yield at the particle size class and the corresponding particle size sediment with the best performance of sediment reduction in heterogeneous sediment under all kinds of combined conditions was verified. All the measured data of all stations in the Yellow River were verified. The article also briefly discusses the human activities (mainly mining) on the benefits of sediment reduction.
