Abstract：By using the particle swarm optimization algorithm combined with the dislocation model， the model for jointly inversing threedimensional slip velocity of fault has been constructed. The threedimensional slip velocity of the main faults in Hexi area was inversed from GPS data in 2001-2004, leveling data in 2001-2004 and gravity data in 2003-2004. The results show that the main faults in Hexi are thrust faults, and all of then have compressional trend. The activities of Altyn Tagh fault, Qilian Mountain fault, HuangchengTa’erzhuang fault and the north part of Longshou Mountain are strong. There the occurrence of earthquake may be related with those fault.
