Forest fires impact on microclimatic and soil conditions in the forests of cryolithic zone (Yakutia, North-Eastern Russia)
Data analysis on the fire occurrence and frequency in Central Yakutia (North-Eastern Russia) has been considered. Calculate the impact of socio-economic and climatic conditions of region on inflammability parameters. A close relationship was found between quantity and density of population and the f...

Data analysis on the fire occurrence and frequency in Central Yakutia (North-Eastern Russia) has been considered. Calculate the impact of socio-economic and climatic conditions of region on inflammability parameters. A close relationship was found between quantity and density of population and the frequency of fires occurence (0.95–0.99). Not so much negative correlation observed between the amount of precipitation during the fire-dangerous period and the frequency of fire (–0.53). The results of our study relating to the fire impact on microclimatic and soil conditions of the forests of Central Yakutia are brought in the article. Studies have revealed that strong changes microclimate and soil conditions in the burnt areas occur in the first 10 years after the fire.
