目前应用计算机数值模拟研究风成沙丘的动力过程、影响因素、形态变化已经取得长足进展，我们在梳理计算机数值模拟风成沙丘研究文献的基础上，通过分析比较不同模拟方法，指出数值模拟的未来研究方向应该朝着高精度参数获取、验证指标的建立、多尺度耦合的实现、不同沙丘类型之间的转换等方向发展。

When it comes to the computer numerical simulation study of dynamical processes， influencing factors and morphological changes of dunes， we have been made some advances and gained a series of important conclusions. On the basis of summing up the previous study conclusions in this topic， we use different methods to analyze the results of different assess their advantages and disadvantages. So we can get a clear vision in the study direction. More importantly， it is pointed that more attention should be paid to high-precision parameter obtaining， the establishment of verification index， realization of multi-scale coupling， and the conversion among different types of dunes， and so on.
