%X The intensities, correlation coefficients, scales and spectra of velocity components of turbulence in the atmospheric surface- layer in the city of Guangzhou are studied using data from an UVW anemometer. The models of velocity spectra in different stratified atmosphere are also approached. The results show that in the urban surface- layer,the turbulent behaviour is nearly consistent with the laws of local isotropy in the inertial subrange, the velocity spectra conform to Kolmogorov's similarity theory. The turbulent energy (especially for the vertical wind component) in the coastal city surface- layer, because of the increase of the surface roughness in the wind di -rection, is larger than that over flat and homogeneous terrain.
