摘要
定量分析内蒙古十大孔兑输沙量是分析十大孔兑对黄河干流河段造成淤积影响的前提与基础。本文充分利用现有水沙资料,采用相关性分析与频率曲线分析相结合的方法对十大孔兑年输沙量进行估计与插补,在此基础上与前人研究结果进行比较分析。研究结果表明,除50年代推算值与其他两家推算结果相差较大外,其他年代计算结果较前人成果接近,故认为本次推算方法和计算结果基本合理。
Quantitative analysis of sediment transport amount of ten tributaries of the Yellow River in Inner- Mongolia is the premise and basis to analyzing the importance of ten tributaries to the main Yellow River depo- sition. In this paper, making full use of the existing water and sediment data, the annual sediment transport a- mount of ten tributaries is estimated and interpolated with the integrated method of correlation analysis and fre- quency curve, and the result is compared with others. The result shows that the estimated values are almost the same as the results of other methods except those in 1950s. Thus, this method and the result are basically reasonable.
