Based on the extended Huygens-Fresnel principle,the spatial correlation properties of partially coherent vortex beams in the turbulent atmosphere are studied synthetically in the paper.It is shown that the spectral degree of coherence and intensity of partially coherent vortex beams depend on topological charges,spatial relative coherence length and refractive index fluctuation et al.In the turbulent atmosphere,the spectral degree of coherence is shown to possess phase singularities,with the increase of spatial relative coherence length,coherence vortex gradually evolves into intenlsity vortex.Oppositely,with the increase of refractive index fluctuation,intensity vortex evolves into coherence vortex.
