Abstract

In this paper, we collected 457 samples of AGNs. According to the theory that the evolution of AGNs is the change on the timescale of the Universe;we discussed the influence of the redshift on the evolution. The results of our analysis indicates that the evolution of AGNs could be divided into two parts (1) one is from quasar to Seyfert galaxy, (2) the other is from FSRQ to BL Lac then to Radio Galaxy.
