Abstract By processing three period sophisticated leveling data of Xinjiang，including year 1951—1969，1976—1984 and 1991—1999，with the dynamic rank defect free network adjustment，we obtained the presentday crust movement rate map and gradient map and analyzed the crust vertical movement characters and predicted its future trend on the basis of the maps.Meanwhile the relations among vertical crust movement rate，vertical velocity gradient and seismic activity are analyzed with the collection of strong earthquakes（Ms≥7）since last century.The study shows that in network covered region，strong earthquakes mainly occure in or around the gradient abnormal zones with the rising crust vertical velocity rate.
