On the basis of the analysis of the non-simultaneous data from satellites Landsat, snapshots of a
high-resolution КФА-1000 and materials of land observations the estimation of area change of dominating
types of vegetation on territory including a central part Urengoys deposit is conducted. In operation
some algorithms of classification of types of a surface, from which one, in the total were utilized, the algorithm
of Minimum distances shown the most authentic outcomes was selected. The state transition of
an earth's surface also was estimated on spectral indexes NDVI and SWVI, and, SWVI has appeared by
more informative, that contacts to features of transformation of tundra vegetation after fires. It is found
that for period with 1978 on 2001 on researched territory, change has exposed about 31,6% of square,
from them about 7,6% at the expense of construction of objects and 24,0% because of attendant fires and
defoliating. For period with 1988 on 2001 square of deer lichen (Сladonia rangiferina), as main
geobotanic indicator of anthropogenous load, has decreased on 5,7% that in some times it is less, as contrasted
to by similar period from a beginning of an opening of a deposit.
Keywords: tundra vegetation, oil and gas objects, remote sensing of the Earth, classification of the vegetation types, geobotanic indicators, anthropogenous load
