Abstract: This paper discussed the conception, characteristics and damages of black wind storms,Placing emphasis on the formation dynamics of strong black wind storms. Plentiful sand and dust sources constitute the material basis for the occurrence of black wind storms, while the unstable air is their important thermodynamic condition. In addition, the paper also descussed the geomorphological and anthropogenic fsctors causing the black wind storms and their main damages and finally puts forward four agricultural hszard reduction measures, namely fencing off the sandy land to rehabilitate the vegetation and protecting natural vegetation ; establishing protective forest to protect oases;establishing farmland shelterbelt to halt wind erosion; and fixing shifting sand with engineering and biological measures.

Key words: Black wind storm, synoptic phenomena, Unstable air
