Аннотация

Forest fires have an impact on forest stands, atmosphere and soils in forested areas. Many authors have established that the thermal effect on the near-surface layer of soil can have a negative impact both on the soil itself and the further development of grass stands and forest stands. It is necessary to develop systems for geoinformation monitoring, taking into account the thermophysical processes in the soil layer at the level of mathematical models. It is necessary to conduct experiments to verify such models. Experimental equipment is proposed in this paper to physically simulate heat transfer processes in a layer of model soil under the influence of relatively high temperature. It is considered the source of which is an inert heater. A set of thermocouples is installed in the soil layer at different depths of the soil layer. Typical curves are presented showing the temperature depend on time at different depths of the soil layer. The results of preliminary analysis are presented. Heater temperature is approximated using one-phase exponential decay function with time constant parameter. Considered equipment can be modified to use gas burner or model forest fuel ignition to simulate forest fire impact on soil layer.
