摘要

格鲁吉亚橡树(Quercus iberica Stev.)主要分布在格鲁吉亚东部温和干燥的气候区。格鲁吉亚橡树自然生长在海拔500-1000 m的地方,在南露坡上可以达到1400 m。格鲁吉亚的橡树林以单一和混合林分的形式呈现。在佐治亚州栎林的活生物量中,总共积累了10,324 Tg C,其中地上生物量为7765 Tg C(75.2%),地下生物量为2559 Tg C(24.8%)。0.616 栎林的枯树和倒腐木中碳的累积Tg。单位面积碳储量达到2.48 t/ha。森林死亡盖度- 0.637 Tg C(2.6 t/ha)。土壤- 23,480 Tg C(94.6 t/ha)。在乔治亚州以橡树为主的森林中,累积了35.06 Tg C,相当于从大气中吸收的128.6 Tg CO2。在空气交换过程中,乔治亚州以橡树为主的森林分布于248313 ,平均每年从大气中吸收565 Gg CO2,向大气中释放438 Gg O2。

Carbon Stock Sequestered in the phytocenosis of oak forests in Georgia

Georgian oak (Quercus iberica Stev.) is basically prevailed in moderately warm and dry climate zones of Eastern Georgia. Georgian oak naturally grows at elevations of 500–1000 m above sea level, it can reach 1400 m on the southern exposure slopes. Oak forests in Georgia are presented in the form of single and mixed stands. In total, in the living biomass of oak forests of Georgia 10,324 Tg C are accumulated, 7765 Tg C (75.2%) of this amount accounts for the aboveground biomass, and 2559 Tg C (24.8%) for the belowground biomass. 0.616 Tg of carbon are accumulated in the dead standing trees and fallen deadwood of the oak forests. The carbon stock per unit area attains to 2.48 t/ha. Forest dead cover - 0,637 Tg C (2.6 t/ha). Soil - 23,480 Tg C (94.6 t/ha). In the oak dominated forests of Georgia 35.06 Tg C are accumulated that correspond to 128.6 Tg CO2, absorbed from the atmosphere. In the process of air exchange, oak dominated forests spread in Georgia on 248313 ha annually absorb from the atmosphere 565 Gg CO2 on average and release in the atmosphere 438 Gg O2.
