摘要

沙丘地貌学包括沙丘形态、组成物质及形成过程等3个方面的研究,野外观测、物理模拟及数值模拟是沙丘形成过程研究的主要方法。目前,随着"3S"技术及计算机技术的发展,沙丘动力学数值模拟方法在沙丘地貌研究中已很活跃。沙丘周围流场变化导致沙丘不同位置气流剪切力的不同,对沙丘形态的塑造起着至关重要的动力控制作用。本文主要介绍了沙丘周围流场动力学数值模拟研究工作所采用的方法及所取得的主要成就。

Abstract

Dune dynamics includes morphology, composition and formation process. There are mainly three methods used on formation process study: field experiment, physical simulation and numerical simulation. At the moment, with the technical development of 3S and computer, the dynamic numerical simulation on formation process of sand dune is very active. The flow variation around sand dunes results in difference of shear stress, which makes control effect on the pattern of sand dunes. The mainly used methods and achievements on the flow around sand dunes are presented in this paper.
