Analysis of Ecological Condition of Taiga Topsoil During Commercial Development

Sivkov Y., Nikiforov A.

Journal of Ecological Engineering

2018

Vol. 19, nr 1

163--169

The paper analyses the ecological properties of taiga topsoil during its commercial development and assesses the consequences of impact which will be made by the future facilities on the environment (taking into account the types of impact, their characteristics, the tendencies of transformation in the nature systems growing with the increase of service life, which were detected at the producing fields), sanitary and socioeconomic aspects of the facilities operation under the conditions of specific geographical complexes. The object of study included waspodzolic and swamp-podzolic soils located in the Uvat district in Khanty-Mansiysk Autonomous Region of Tyumen region, in the area of potential impact of industrial facilities. The method of study implied the selection of soil specimens and their examination according to the standard practices. Ten specimens were taken from each of three areas of sampling. The specimens were subjected to office study in order to determine eleven parameters. The sources of impact made by the oil and gas facility on the environment were the material objects (buildings, constructions etc.), elements and assemblies of basic and auxiliary technologies which result in pollutants emission. The major impact on topsoil at the stage of preparatory works and construction of facilities was the mechanical damage to the natural state of soils. It is primarily connected with sites stripping from forestry and ground leveling. The paper reviews the issues of ecological condition of topsoil and forecast of possible changes while commercial development of the studied area. A negative load on soil may be decreased through planning and implementation of organizational measures on assessment of current state of the topsoil within the field and environmental threat from basic and auxiliary industrial facilities.
