Abstract In this paper, the diffusion source model and the structure of magnetized accretion disk with self-gravity are used to study the density and the ionization parameter of the HII and H*1 zone, of which most likely the broad line emitting region consists. Two different densities and ionization parameters are determined: the first < n( HII) > and Ξ( HII) , corresponding to the mean density and ionization parameter in the completely ionized HII zone, and the second,< n (H*1) > and Ξ(H*1), to the mean density and ionization parameters in the H*1 zone.
