Studying Changes in the Tazovsky Peninsula Vegetation Cover Based on Satellite Images. Arctic: ecology and economy, 2011, no. 4(4), pp. 46-57. DOI: . (In Russian). Abstract: The possibility of quantitative estimations of man-caused vegetation disturbances in the regions of oil-and-gas field development in the Russian subarctic zone using satellite images of different years is considered and justified in the paper. Based on analysis of NOAA and Landsat archive satellite data of 1988 and 2001, variations in the area of dominant types of natural tundra and forest-tundra vegetation cover were estimated for the first time for Tazovsky Peninsula (at a small scale) and for the Urengoy oil-and-gas condensate field (at a large scale). The investigation was based on surface-type ranking as well as on variations of spectral indices (NDVI and SWVI) and the radiation temperature. As established, the natural tundra-type vegetation (burnt reindeer moss) is mostly replaced by the following secondary species: grasses, low shrubs and green mosses, such disturbed zones being principally found close to oil-and-gas fields and gas-main pipelines. According to the results achieved, in 2001 the area of transformed (secondary) vegetation equaled about 14% (10 000 km2) of the Peninsula surface. The developed procedure may be used when drawing different- scale maps of man-caused transformation of the vegetation cover in the Arctic and subarctic regions of active economic development.
