The invention relates to a method for calculating a central region effect of a northbound component of external disturbance gravity, which is technically characterized by comprising the following steps of: calculating the central region effect of the northbound component of the external disturbance gravity by utilizing a generalized Stokes formula, and extracting a main item of the generalized Stokes formula for calculating the northbound component of the external disturbance gravity; adopting plane approximate conversion and Taylor series expansion under a polar coordinate system for main items of the generalized Stokes formula, an external disturbance gravity north component central region effect calculation formula is obtained, and the calculating high-precision external disturbance gravity north component central region effect through the formula. The method is reasonable in design, the generalized Stokes formula is adopted to calculate the central region effect of the external disturbance gravity north c
