摘要
通过研究国内外现有的河型判别式及其建立的过程,结合河型研究的出发点和归结点认为,理想的河型判别式应该同时具有河型判别、河型预测和河型控制三项功能,河型判别、河型预测、河型控制应该采用同一种表达式。为了使河型判别式同时具有三项功能,唯一的办法是依据河型成因建立河型判别式。河型成因问题不解决,河型判别、河型预测和河型控制问题不可能达到根本的解决。
Based on existing studies on channel pattern discriminants for alluvial rivers, the authors concluded that a good channel pattern discriminant should have at least three functions, i.e. discriminating, forecasting and instructing. Such discriminant could be established if it is purely based on the formation causes of channel pattern. Therefore, it may not be possible to develop an expression with all the three functions if the problem of formation causes of channel patterns remains unsolved.
