The invention discloses a near-surface meteorological element calculation method. The method mainly comprises the steps of collecting the meteorological related data of a target area; dividing the target area into an area A, an area B, an area C and an area D; determining an optimal input variable combination by using an ANN method; determining an optimal ANN mapping model according to the optimalinput variable combination; calculating meteorological element calculation data of the area B; calculating the meteorological element calculation data of the D area, wherein the station meteorological element data of the area A and the area C and thecalculation meteorological element estimation data of the area B and the area D jointly form the near-surface meteorological element data of the target area. According to the method, a remote sensing method and a spatial interpolation method are combined, so that the calculation error caused by station sparseness is effectively reduced, and the problem of near-surface met
