The column density distribution of the Lyman alpha forest is predicted for a minihalo model in which the baryon clouds responsible for the absorption lines are supposed to be in gravitational equilibrium under the potential of cold dark matter. It is determined primarily by the density profile across a typical cloud. The evolution of minihalos within various environments is discussed in relation to the redshift dependence of the Lyman alpha forest.
