Yardang landforms research is one of the important contents in aeolian erosion landforms research, but it is weaker than Aeolian deposition landforms research at present. Yardang landforms, named by Sweden explorer Seven Hedin in 1903, have been studied over 100 years. Although many scientists made important progress with the technological improvement and methodological update in the history, lots of issues have not been resolved. In this article, the authors summarize the progress and issues in 8 aspects, including scientific definition, spatial distribution, morphology character, formation and evolution conditions and processes, formation chronology, relationship with environments and classifications. Base on the abovementioned, we make research prospects in the future, and give some suggestions,which include clarifying scientific definition, field investigation combined with laboratory quantitative study, breaking research bottleneck of formation chronology, relationship between Yardangs and environments in deep and increasing research fund.
