    The propagation properties of the 1+2-dimensional super Gaussian shaped optical beam in strongly nonlocal nonlinear media are discussed by means of variational approach. A set of parameter evolution equations, a critical power and an approximate evolution law of the beam width are obtained. In the general case, the beam width of the 1+2-dimensional super Gaussian shaped optical beam in strongly nonlocal media takes periodical oscillating variation with sine and cosine shape. But the beam width remains constant and the spatial optical soliton is formed when the input power equals the critical power. The critical power increases with the order of optical beam, but is independent on the order of phase factor. The speed of phase shift of the spatial optical soliton is related with the order of optical beam, the order of phase factor and the initial power. As the order of optical beam gets higher, the order of optical beam and the initial power plays more important role, and the effect of the order of phase factor can be ignored.
