摘要
基于近代关于流域汇流机理是地貌和水动力扩散作用的新观点，导出了根据霍顿（Ｈｏｒｔｏｎ）地貌参数计算ｎ和根据地形资料计算Ｋ的公式，并用实例作了检验。本文将有助于深化无资料情况下汇流计算方法的研究。
The equations of determining the parameters n and K in the Nash model are deried according to a newview that the mechanism of watershed concentration now results results from the combined effect of geomorphological and hydrodynamical dispersion.These equations are represented by the Horton's geomorphology parameters andits rationality is proved by means of the rainfall-runoff data of Gengwangzhuang basin.
