The potential of paludification is one of the most important indexes of
that process. It is determinated by mean slope weight value of paludified forests
and mires. The potential of paludification depends on the landscape relief morphogenesis. It intensifies with increasing of mean slope weight value of paludification surfaces. The obtained data testify the process of paludification in the north taiga sub–zone and decreasing of its activity in the mid–taiga subzone. It becomes apparent strongly in landscapes with hilly ridge relief. The potential of paludification of denudation–tectonic landscapes in the north taiga sub–zone 3–4 times as large than in the mid–taiga sub–zone but there is no difference in landscapes with plain relief.
