| Popis: | Soil respiration includes soil microbial respiration, soil fauna respiration, and plant root respiration, therefore it reflects the biological activity of the soil ecosystems. The Siberian Taiga often experiences serious damage from forest fire, due to the very low precipitation in spring. We measured the soil respiration in five forest soil ecosystems with different histories of forest fire in Yakutsk in August 1997. The dominant tree species was Larix cajanderi, and the soils were Spodosols with a sandy and loamy texture. We also measured the soil respiration in a grassland. At severely burned sites, almost all the trees had fallen, litter and vegetation on the forest floor had burned, other forms of vegetation, including bryophytes or herbs, had invaded. At less severely burned forest sites, the trees were still standing but litter and vegetation on the forest floor had disappeared. Soil temperature, moisture, pH, and EC all increased after severe forest fires, the A-horizon showed a higher or... |
