Spatial vegetation distribution and zonal vegetation type on islands in southern part of the Lena Delta (Eastern Siberia)

Abstract

In this research spatial distribution of the different vegetation types on Lena Delta islands described in connection with their relief, time of formation and geological substrates. It was shown that zonal vegetation can be find only on third river terrace on gentle slopes. Because of continuous permafrost predominant vegetation is presented by hydro serial communities united into successional cycles. Zonal vegetation types occupy not more than 1-2% of the whole area.
