Updating regional fire hazard scales for forest areas of Krasnoyarsk Krai

Abstract

Due to the intensive industrial development of the territory of Krasnoyarsk Krai, significant changes have taken place in the vegetation cover and the number of fire sources has increased. Due to climate change, the number of lightning discharges, which are the main cause of forest fires in the underdeveloped northern territories of the region, has also increased. The development of a regional fire hazard scale for weather conditions is caused by the fact that the existing unified federal fire hazard scale for weather conditions does not accurately characterize the fire hazard of forest areas in the region and does not allow rationally regulating the work of forest fire services and forestry. On the basis of data on the number and area of forest fires and the causes of their occurrence, generalizations and analysis of the timing of fires and the causes of fires in the forest areas of Krasnoyarsk Krai were performed. It is revealed, that in modern conditions the area of the region is characterized by an increase in fire activity. Due to the complexity of the relief, the diversity of climatic and forest conditions for each forest area, we have constructed regional fire hazard scales for weather conditions and compared them with the unified federal scale. The use of fire hazard scales developed by us for the forest areas of the Krasnoyarsk Krai will allow timely detection and extinguishing of forest fires and, consequently, reduce damage from forest fires.
