Abstract: This paper briefly describes the peculiar geologic background of Dushanzi area,such as the newest erogenic movement,distinctive materials produced by mud eruption,broad gobi plain and particular deposits of depression. The geologic factors related to geologic background,including the foundation soil,topography,fault,colapse and landslide are also characterized by their regional particularity. Five earthquake hazards zones have been classified as A,B,G,D and E,on the basis of the analysis of seismic Vulnerability of geologic factors. According to the differences of ground effects in each zone,it is suggested that land utilization should avoid the southern zone but dwell on the northern zone,i. e. avoid the mud volcano and mountain front depression,but dwell on the gobi plain.
