After taking account of the selection effects in the identification of emission lines and choosing the sample within a narrow range of absolute magnitude, we can investigate the evolutionary function of quasars from their redshift distribution. From data given by slitless surveys with limiting apparent magnitude 19.5, we find that the evolutionary function takes form of ρ = ρo(1+z)6.5±1. The analysis has also showed that the observational redshift distribution of quasars is compatible with cosmological principle.
