The study estimates the landscape-recreational potential of the Ob left bank plain according to biological parameters. For functional estimation of recreational suitability of environmental components of investigated territory following biological characteristics were used: territorial coverage with forest, variety of useful plants (fruit, berry and medicinal plants), variety of kinds of the hunting animals and birds, fish resources. Basing on mark estimation of biological parameters the researcher has allocated three zones differing by prevalence of that or those parameters.

Key words: landscape-recreational potential, horizontal dismemberment, vertical dismemberment, landscape, coverage with forest, variety of useful plants, specific variety, moistening of territories, recreational suitability.
