Four user platforms were laid – two on the terrace with sea grass-meadow vegetation and two on the bottom of the coastal slope Cape Canning under Erman and oak with bamboo forest. Vegetation description given. The structure of profiles and the morphological characteristics of soils were shown. The terrace on the sea developed sod-meadow soils, and on the coastal slope – burozems raw-organic humus ocherous. Feature exposed soil profiles is the lack of clear-cut ash horizons. Each plant has a specific association type soils was found. Under the stone birch is an intensive accumulation of humus at a lower pH than in soils under grass-meadow vegetation.
