An approximate statistical description of the formation and evolution of structure of the Universe based on the Zel'dovich theory of gravitational instability is proposed. It is found that the evolution of dark matter (DM) structure shows features of self-similarity and the main structure characteristics can be expressed through the parameters of the initial power spectrum and cosmological model. For the CDM-like power spectrum and suitable parameters of the cosmological model the effective matter compression reaches the observed scales Rwall∼20–25h−1 Mpc with the typical mean separation of wall-like elements DSLSS∼50–70h−1 Mpc. This description can be directly applied to the deep pencil beam galactic surveys and absorption spectra of quasars. For larger 3D catalogues and simulations it can be applied to results obtained with the core-sampling analysis.
