Abstract: | Consideration is given to the results of studies on the postfire dynamics of Transbaikal forests, which are formed under conditions
of highly arid climate and extreme pyrological regime. Data are presented on tree die-off and recruitment in naturally burned
forests and in test stands affected by creeping fires differing in intensity. The hydrothermal regime of soils, precipitation
runoff, and its multifactor models are discussed. It is shown that fires aggravate moisture deficiency on mountain slopes,
impair the productivity of tree stands, and cause their digression. The statistics of forest fires and the risk of lightning
fires are analyzed. |
