Fire classification in natural ecosystems by physical and environmental characteristics
Abstract
To qualitatively and quantitatively characterize and classify the intensity of forest fires and their environmental consequences, it is necessary to develop a special scale similar to the scale of wind strength, sea storms, earthquakes, geomagnetic storms, etc.
Purpose. To describe the scales developed for the classification of forest fires according to various parameters characterizing physicochemical processes, environmental consequences and the level of danger from pyrogenic factors.
Methods. System analysis, multifactorial analysis, mathematical modeling.
Results. A seven-magnitude scale for classifying forest fires by intensity, energy characteristics, mass of emissions of the main combustion products and related chemical elements, as well as by environmental consequences and hazard level is proposed. It is substantiated that with moderate and weak winds, the intensity and energy of forest fires in Ukraine usually do not exceed 4-5 magnitudes, i.e., a moderate or high level. Fires of this level occurred, for example, in the spring, summer, and fall of 2020 in a number of regions of Ukraine.
Conclusions. The developed special scales for classifying forest fires according to various parameters are an effective tool for qualitative and quantitative characterization of the intensity of forest fires and their environmental consequences. The obtained results can also be used to assess environmental impacts, material damage and social losses.
