Влияние плотности торфяных почв на возникновение ландшафтных пожаров

Abstract

The purpose of experimental studies is to determine the propensity to spontaneous combustion and forced ignition from heated bodies of peat samples at different densities. This article discusses the problems of the occurrence of natural fires on reclaimed developed peatlands introduced into agricultural circulation under the black culture of agriculture, which has become widespread in Russia, the causes are identifi ed and ways to solve this problem are proposed based on experimental studies. It has been established that the possibility of the occurrence of processes of spontaneous combustion and forced ignition of peat soils is mainly infl uenced by the density of the upper peat layer, due to the infl uence on thermophysical properties, such as thermal conductivity coeffi cient, thermal diffusivity coeffi cient, volumetric heat capacity coefficient. As measures to change the thermophysical properties of the surface of worked-out peatlands, special treatments are proposed using the prevention of pyrogenic destruction of agricultural land.
