Abstract ： Edge plasma parameters, including electron temperature Te , density ne , plasma potential Фp , radial electric field Er and the corresponding fluctuations in the Sino-United Spherical Tokamak, have been systematically measured with Langmuir probe arrays. Wavenumber spectrum analyses show that edge fluctuations have a radial propagation character of the drift wave turbulence, with a characteristic radial phase velocity vphr ～ 0.7 km.s-1 in the scrape-off layer and vsuB>phr ～ 0.9-1.4km.s-1 in the plasma edge.
