Растительный покров болот богатого грунтового питания Южно-Уральского региона (в пределах Челябинской области)

Abstract

Two groups of fen vegetation were designated in course of our study: 1) South Ural mountain spring fens; 2) non-spring mountain and plain fens with groundwater feeding. The structure of their vegetation cover is studied. It is shown that despite the intrazonal character of mire ecosystems, fen vegetation observed has its own geographical peculiarities depending on regional and altitude belt structure of South Ural region. The analysis of peat deposits from the fens studied demonstrated that the composition of vegetation communities observed has almost not changed since their formation until now. There are just small variations in species share proportions in the structure of palaeocommunities. Thus we conclude that the environmental conditions of the fen habitats had insignificantly changed during the Holocene.
