Characteristic vegetation Ketchimovskogo field

The Main problem of the study and description of the vegetation of oil fields in Nizhnevartovsk region is currently difficult to cross the territory. Only the areas adjacent to roads and industrial sites are available for field research. Effects on plants and communities of oil production is possible both direct and indirect. In the process of setting up and operation of oil fields changing plant community structure and composition, there is a replacement on derivatives. During the growing period in 2013-2014 was conducted description of the vegetation of the field and the identification of changes in the structure and composition of plant communities. The aim of this work was the definition of rare and endangered species. Total number of descriptions - 54. Standard method was used geobotanical descriptions. The result was the identification of the typical plant communities and their description. In the paper, the characteristic vegetation Ketchimovskogo field located in the North-Eastern part of the Nizhnevartovsk district. Zonal vegetation on site Ketchimovskogo deposits are pine long-sphagnum and shrub-sphagnum forests in combination with shrub-sphagnum oligotrophic bogs. This type of vegetation is characteristic of badly drained flat surfaces of watersheds, speckled with tiny tatahouine depressions. Such locations are characterized by the distribution of peat or peat-gley soils with low upland peatlands and for a long period of abundant moisture. The distribution of this complex plant communities due to cryogenic processes and long-term conservation of soil and dirt perched water, enabling the logging of upland forests on soils of different mechanical composition. Zonal type of wetlands in this region are oligotrophic sphagnum bogs with the dominance of Sphagnum fuscum. In river valleys and on the first floodplain terraces are observed eutrophic sedge and sedge-hypnosia marshes, which in this subzone have little meaning. On-site deposits of this type of wetlands combined with oligotrophic and mesotrophic bogs on their periphery and in the center of them. Their distribution is due to the formation of zones of flooding during the construction of linear structures.
