摘要
研究河川径流、泥沙沿程分布规律时,本文提出的河川径流气泥沙沿程曲线法较传统的区间百分比柱状图对比法为之简单、一目了然,是研究水资源空间分布规律的重要方法。
The author in this paper recommends that the columnar chart contrast method which is generally used to study the distributional regulations of runoff, sediment discharge along river course should be substitited by the method of curves of river flow and sediment discharge along the river course. Curves produced from runoff difference are suit to study the runoff distributional regulations along river course Curves produced from the sediment difference are suit to study the main sources of sediment and its distributional regulations along the river course Compare to the traditional columnar chart method, this curves produced from the difference along the river course is much simpler and more obvious It is a very important method for the research of the regional and seasonal distribution of water rescurces.
