Abstract On the basis of crustal gravity isostasy theory,the theoretic isostatic crustal thickness(D) with Airy’s isostatic model in Hexi area was computed. In the same time, real crustal thickness(M) from the Bouguer gravity data was inverted,and then compared these two thicknesses with each other for researching crustal isostatic stability．The results indicate that the value D is generally larger than the value M and it means that the crust is in a monisostatic state.
Key words ：
Hexi area
crustal structure
Bouguer anomaly
vertical deformation
effect of gravity isostasy
