Abstract. Thermal radiation is one of the damaging factors of forest fire. As a result of exposure to radiant heat flow, thermal damage of the human skin is possible. A layer of skin is considered with effective thermophysical characteristics. Thin layer of sweat excretion situated on top of the skin. A mathematical model of heat transfer in the system of "skin-excretion" is developed taking into account evaporation of moisture. Typical simulation results are presented.

“…The analysis of tables allows to draw the conclusion, that longer influence of radiation from 01005-p. 4 forest fire leads to thermal defeat of subcrustal zone at smaller distances from a fire and density of thermal radiation. Logical the conclusion serves that fact, that advancement of an edge of forest fire on more short distance from a concrete tree raises probability of a thermal trauma of this tree.…”

“…There is their damage, fragmentation, destruction as a results of influence of forest fires on forest stands [2,3]. Development of fire impact (influence on forest ecosystems, especially, on forest stands) monitoring and forecasting technologies is prominent aspect along forecasting of forest fire danger [4]. Now overwhelming majority of papers devoted to the analysis of an actual statistical material on forest fires incidents and their ecological consequences [5,6].…”

Abstract. Numerical research results of heat transfer in layered tree trunk influenced by heat flux from forest fire presented. The problem solved in two-dimensional statement in Cartesian system of co-ordinates. The typical range of influence parameters of heat flux from forest fire considered. Temperature distributions in different moments of time obtained. Condition of tree damage by forest fire influence is under consideration in this research.

“…High temperatures of forest fires have a negative impact on forest stands, leading to their damage and even death [3,4]. Besides predicting forest fire danger [5], it is extremely important to develop technologies that predict the damage caused by forest fires to stands.…”

Abstract. We present the numerical simulation results of heat transfer in a layered structure of the root branch when exposed to a high temperature from a forest fire in this paper. The problem is solved by the method of finite differences in a cylindrical coordinate system using a onedimensional formulation. Typical exposure times and temperatures in the forest fire front are considered. The temperature distributions are presented for the system "root fragment-soil-forest fuel-air". We revealed the character of the temperature distribution and the depth of the soil layer heating to the values which are dangerous for the coniferous tree root system.
