Sandy desertification is greatly influenced by wind,and threshold wind of transporting sand is major power shaping desert landform pattern.We analyzed surface wind field from wind speed,wind direction and sand drift potential by surface wind data from four national basic meteorological stations around the Hobq Desert from 1957 to 2014.The results showed that:(1)The correlation of mean wind speed and frequency of threshold wind of transporting sand is significant in the Hobq Desert.(2)Annual mean wind speed ...
