The invention discloses a meteorological ground element interpolation method based on trust propagation, and particularly relates to the field of meteorological data interpolation. The method comprises the following steps: S1, setting a probability density kernel function, and calculating the station density; S2, adding a virtual site; S3, establishing a factor graph by using a k-NN Barns binary factor graph algorithm; S4, carrying out kNN gradient inspection; S5, introducing numerical elevation data, and performing meteorological element interpolation calculation on the station V on the basisof the station-station factor graph by using a trust propagation algorithm; S6, performing meteorological element interpolation calculation on each grid point in the grid point field by utilizing thestation V meteorological element value on the basis of the station-grid point field factor graph; and S7, calculating the wind speed variation. The station-station factor graph and the station-grid point field factor graph ar
