The evolution of the temporal and spatial distributions of the Coronal Holes(CHs), the evolutionary features of the magnetic fields in the CHs and their ralation to the solar cycles are analyzed in this paper by using the CHs data from 1970 to 1995. It is found that the equatorial CHs and the polar ones have opposite evolutionary regularity and characteristics related to the solar cycles.
