The analytical propagation expressions for the average intensity of flat-topped vortex hollow beams in atmospheric turbulence are obtained by using the extended Huygens-Fresnel diffraction integral. And the influences of atmospheric turbulence on the average intensity of flat-topped vortex hollow beams are given by numerical examples. The results show that the flat-topped vortex hollow beams propagating in atmospheric turbulence will evolve into Gaussian-like beam with the propagation distance increasing, and the beam propagating in atmospheric turbulence with larger structure constant class="mathmlsrc">title="View the MathML source" class="mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0030402616307902&_mathId=si5.gif&_user=111111111&_pii=S0030402616307902&_rdoc=1&_issn=00304026&md5=a6945ccbe81781657bcfad2da9cfa038">class="imgLazyJSB inlineImage" height="17" width="16" alt="View the MathML source" title="View the MathML source" src="/sd/grey_pxl.gif" data-inlimgeid="1-s2.0-S0030402616307902-si5.gif">class="mathContainer hidden">class="mathCode">$C_n^2$ will lose its initial dark hollow centre more rapidly.
