| Popis: | To study the temperature regime of soils, an autonomous atmospheric-soil temperature complex is used. The complex is installed at three sites with sandy soil and various kinds of vegetation cover: burnt areas, pine forest, and open sand. Observations are made from October 13, 2011 to August 16, 2019 in a soil profile from the surface to the 320 cm depth. An analysis of the temperature regime of sandy soil reveals main similarities and differences between the three sites with different types of vegetation cover. In summer, the sites with pine forest and burnt areas of pine forest warm up less intensively than the site with open sand. Due to the greater openness, this site is the warmest during the warm period. In winter, pine forest, due to its high vegetation, is a barrier to wind, reducing snow blowing, and prevents the radiation cooling of the surface. To a slightly lesser extent, these functions are performed by loose vegetation in the burnt areas. The influence of vegetation under different weather conditions (clear sky/overcast) is considered. Cloud cover, as well as vegetation, helps to reduce the variability of soil temperature. The results of the study show that after forest fire restoration of vegetation cover naturally contributes to the partial restoration of the soil temperature regime. |
