冲积河流河型分类的依据及数学方法分析

Analysis on Basis and Mathematical Method of Channel Classification of Alluvial River

摘要: 河型分类不统一给河型研究带来很多不便。根据河流动力学、河床演变基本理论以及数学原理,对河型按成因进行分类,从而有利于解释河床演变机理。由于河型分类问题具有模糊性,因此,河型分类问题应该采用模糊数学方法进行研究。

Abstract: The different classifications of channel bring a lot of inconvenience to study it.Based on the dynamics of river,basic theory of fluvial process and mathematics,with the forming reasons of river channel to classify the channel and explain the principle of the fluvial process.Because of the fuzziness feature of channel classification problem,the channel classification problem should be studied by the fuzzy mathematics method.
