The invention discloses a method for establishing and visualizing a spatial dynamic particle model in three-dimensional virtual earth software, which comprises the following steps: acquiring grid dataparameters, obtaining position information of spatial particles in the grid, and interpolating the particles to realize continuous motion of the particles and construct a vector field; creating a three-dimensional scene in the three-dimensional virtual earth software and driving the spatial particle model to create particles through an interactive operation; continuously updating particle state and position to realize dynamic display of the spatial vector field data according to a set time interval, and. The method for establishing and visualizing the spatial dynamic particle model in three-dimensional virtual earth software in the invention integrates the flow field data into the three-dimensional virtual earth software for three-dimensional dynamic display, achieving instantaneous stateand particle motion track of the flow field with good user interaction experience, high operation efficiency, clear and smooth rendering and high precision.
