本文讨论利用重力资料反演莫霍面时，地壳横向不均一性，密度随深度变化以及异常数据滑动平均处理对解释结果的影响程度。
The lateral inhomogeneity and the variation of density contrast with depth in the crust and their effects on the inversion of gravity field are discussed.
在从观测布格重力异常中扣除上述密度异常引起的重力异常后的数据基础上，直接反演了中国西北区域莫霍界面的深度。
Subtracting the gravity anomalies caused by density anomalies from the observed Bouguer anomalies, we inversed the depth of Moho of northwestern China by using the residual anomalies.
