摘要

The Alpine group of landscapes includes the following salient typos:n1. the landscape of the bald mountain tops and slopes with its rock waste, talus, mountain terraces, rare glacial forms in the shape of curries with a moss-lichen cover on a rocky substratum and scattered sedge meadows with a thin layer of mountain-meadow soil.n2. The landscape of the northern slopes with a cedar and cedar-large taiga. The slopes are relatively steep and covered with a thin layer of fine earth;there is abundant gross-type forest soil covered with cedar-begonia, berry cedar and cedar larch taiga with a small admixture of birch and pine.n3. The landscape of the southern slopes with a cedar-larch taiga and motley grass covered steppe sections. Most of the slopes are gentle and rocky, and the soil cover is made up of dark grey forest soil and mountain chernozem. The cedar-larch taiga covers mostly the upper portions of these slopes, with edge, meadow grass, alpine aster, anemone, cinquefoil and other types of motley grass growing on the lower parts.n4. the landscape of the narrow mountain valleys with Arctic birch of the willow family not subjected to glaciation, the valleys are several dozens to several hundred meters wide, flat bottomed with indistinct flood plains frequently littered with boulders and large blocks. The valleys are highly humid and frequently swampy which accounts for the marshy meadow soil around there. There is little grass in the Arctic birch forests but a fairly widespread moss cover.n5. The landscape of the narrow mountain valleys with glacial deposits. It differs from the previous landscape by its more inlet hills and small sinkholes occasionally filled with water. The shady slopes of the hills are usually covered with larch and birch groves.
