Summary: | The data on carbon stock and its distribution on the main pools in the ecosystem are presented for mature pine forest bilberry type in the middle taiga. The ecosystem of mature pine forest bilberry type concentrates 158.2 t C ha–1. Upper 1 m soil layer contribute 53 %, phytomass – 44, coarse woody debris – 3 % to total carbon stock. Net primary production is determined. Input of stand is 70 %, ground cover – 30 %. It is found active accumulation of wood. It forms about 36 % of biomass production. Litter fall and it distribution on separate fraction are characterized. Litter fall ranged from 1.13 to 1.53 t C ha–1. It is equal 3–5 % of forest floor mass. The tree plants are generating the most part of litter weight. Needless and leaves play the key role in litter of stand. Inactive fraction (branches, cones) are characterized by big inter-annual variation in litter fall production due to changing weather conditions during study period. Dynamic soil temperature is described on lower boundary of forest floor. We estimate that during growing season carbon flux from soil surface is 2.28–3.21 t С ha–1. |
