Ecological-geographical Assessment of Nature Reserve (Zakaznik) "Gerbikanskiy" (Amur Region)

Year: 2018, Number: 3, Pages: 21-42

The thematic mapping of dangerous exogenous geological processes and hydrological phenomena, soils, vegetation and landscapes on a scale of 1: 150000 was carried out for the territory of the Zakaznik "Gerbikanskiy". The analysis of the obtained cartographic materials was carried out, which showed the current state of the territory. Assessment of the ecological significance of the natural ecosystems of the SNR "Gerbikanskiy" and its individual natural objects is given. In the relief of the reserve there are kholmogorye (44,8 % of the total area), low mountains (51,6 %) and middle mountains (3,6 %). The territory of the reserve has complex engineering and geological conditions associated with the widespread occurrence of permafrost. Vegetation has a haze-mountain-taiga character with a predominance of zonal larch forests (from Larix gmelinii) and azonal wetland vegetation. The boreal forest vegetation occupies the largest areas (82,6 %). Rare communities should be considered: pine and larch-pine forests; communities with Juniperus sibirica; communities with rare species such as Eriocaulon chinorossicum, Corallorhiza trifida, Epipogium aphyllum, Hammarbya paludosa, Listera savatieri, Cortusa amurensis, Saxifraga selemdzhensis, Rhizomatopteris sudetica; community, where there is an extreme option of mixing boreal and non-moral elements. According to preliminary data, about 250 species of vascular plants are found in the Zakaznik "Gerbikanskiy". In the soil structure of the reserve, the largest areas are occupied by rusts and burozemes (43,5 %). The remaining areas are occupied by hydromorphic soils - glezemy, gley, peat and alluvial soils. Glezems, peat and gley soils belong to the permafrost soils, they formed on permafrost soils and themselves support and preserve the permafrost. The mosaic of landscape is quite high, which provides a great variety of habitats for the animal population. The ecological significance of the natural ecosystems of the Zakaznik "Gerbikanskiy" both on a regional scale and in the planetary one is very high. Natural reserves of the reserve are especially representative for the biogeographic mountain-taiga region. The reserve has large (48 %) wetland areas, recognized by the world community as refuges of specific biodiversity and climate stabilizers. The reserve is of particular value for maintaining genetic and ecological diversity in the region due to the quality and originality of its flora and fauna.
