Carbon Storage and Its Distribution Characteristics in the Planted Forest of Larix prinicipis in Southern Daxinganling
摘要
Abstract
This study was conducted in Saihanwula forest ecosystem national research station in southern Daxinganling. Our main subjects were to determinate carbon storage and distribution characteristics of carbon storage in the planted forest ofLarix prinicipis, by using the method of combination of plot-level survey and laboratory analysis.The results showed that the total carbon storage of Larix prinicipis plantation ecosystem was in the order of 32 a (205.83 t·hm-2)>28 a (186.38 t·hm-2)>16 a (155.84 t·hm-2); Carbon storage of the vegetation layer was 9.11~26.73 t·hm-2, contributing 5.85%~14.0% to the total carbon storage of the ecosystems, as it grew and then decreased with age; The carbon storage of litter layer was 0.29~0.40 t·hm-2,which contributed 0.19% to the total carbon storage of the ecosystems,with the increase of forest age tends to be stable;The order of carbon storage of soil layer was 32 a (178.70 t·hm-2)>28 a (159.92 t·hm-2)>16 a (146.44 t·hm-2), contributing 86.82%~93.96% to the total carbon storage of the ecosystems, as it decreased with age; The carbon storage ofLarix prinicipis plantation stage characterized by soil layer>vegetation layer>litter layer, underground>aboveground;The biggest carbon storage of the vegetation layer was the tree layer (6.85~26.46 t·hm-2), about 75.21%~98.99%, in which the trunk dominants (2.53~14.98 t·hm-2) of 36.93%~56.61%, and the carbon storage increased with the forest age. The carbon storage in the soil layer mainly concentrated in 0~30 cm soil layer, which contributed 70.78%~78.82% to the total soil carbon storage.The results can provide theoretical basis forLarix prinicipis plantation management and efficient cultivation.关键词
