Krajobraz eoliczny wyspy Jarki na północnym Bajkale

Abstract

Against the background of general characteristics of physicogeographical conditions of northern Baikal and its neighbourhood the origin (lagoon formed in result of accumulation of lacustrine and fluvial deposits of the Verkhnaya Angara and Kichera) and de-velopment of Yarki island were presented, taking the special account into its contemporary degradation under the influence of natural factors (general development of Baikal rift) and anthropogenic ones: tourism development, vegetation disturbing, dune blowing out and their washing by Baikal waves, intensified after dam building in Irkutsk. The contemporary aeolian relief of island was also described (predominance of blown old dunes and diversifying of aeolian relief by north-eastern and – to smaller degree – by south-western winds, and vegetation, which is floristically poor, weakly diversified and to significant degree changed by human being, was also presented.
