Abstract

The article describes the quantitative relations between characteristics of fires, vegetation and climate data on the territory of the Republic of Tyva. According to meteorological stations in the region since 1970s an increase in the average temperature has been recorded. On the background of small annual precipitation this led to an increase in the duration of active insulation, and as a consequence, sharp increase in the number of wildfires and area burned. During 1975-2005 the air temperature of warm season has increased by 2.9±0.7 °C. With increasing temperature the number of wildfires increased 2.2 times compared to 1960-1990, burned area forest increased 19.6 times. During this period, on forest lands of the region 5020 fires occurred on a total area of 578463 hectares, the average area of 1 fire being 54 ha. In recent years (2006-2016) in warm season air temperature increased by 1,9±0,7 °C. The number of wildfires increased 0.9 times, the area of burned plots increased 19.6 times. During the period 2117 wildfires have occurred on a total area of 461455 hectares, the average area of 1 fire being 198 hectares. Statistics show the catastrophic situation with the fires of the vegetation in the region. On average large wildfires of 85.4 % of all wildfires in the republic. The years have seen 2002, 2007, 2008, 2014 and 2015 most fire with large burned areas.

Keywords
