中文摘要	近半个多世纪以来国内外学者对沙纹各方面有了详尽的研究,使沙纹研究理论逐渐趋向系统化和完善化.在扼要回顾了风成沙纹的研究历史的同时,分别从沙纹形态、沙纹形成过程和沙纹形成中的颗粒分异机制等几方面阐述了沙纹研究的现状及主要进展.最后根据沙纹研究的现状和目前沙纹研究中存在的问题,对将来的研究趋势作了初步探讨.
英文摘要	Research in all over the world has made great progress in the investigation of aeolian sand ripples for more than half century. Also, the theory of aeolian sand ripples has becoming more and more complete. Aeolian sand ripples are the result of the interaction of the sand and airflow. At present, the research is focus on the measurement and description of ripples conformation, the experiment of the formation and simulation of the grain segregation mechanism in the sediment.This paper reviews the development of the research of aeolian sand ripples briefly . It describe ripples conformation , the process of ripples formation and grain segregation mechanism in ripples formation respectively to explain the entire process . It also gives a talk about the problems and the trend of these research in the future. At the same time, it analyzes the results in all the aspects which different researchers get with different method in detail. First, it abstractly overview the history of ripples research up to now. Then show the results we have got from the investigations and experiments. About ripples conformation, we describe the measurement of the element, which characterize the variation of the ripples. On the other hand, it explains the factors that bring about the form of the ripples t and the interaction between them by experiment. In special, it deals with the characteristics, rules and action of the sand flow during the process of the ripples formation. Simultaneously, it summaries all kinds of theoretic about ripples formation which different researchers have got from vary environment all over the world. Also, in other respects of ripples investigation, different scholars have studied with different techniques and educed varied conclusion. Nowadays, there are many disputed question in all facets of ripples, researchers have not agreed with each other in not only ripples dynamics, but conformation and grain segregation mechanism.With the development of technology, our instruments and means are becoming more and more improved . As a result, we can do work more accurately and get more perfect conclusion. Especially with the progress made in the computer, we can anticipate numerical simulation with computer will play an important part in the study of ripples. And in the future, our study will comply with the evolution of desertification in order to content the requiring of the construct.
