Carbon storage and its allocation of 4-, 8-, 12-, and 16-year-old Armeniaca vulgaris plantation ecosystems on the eastern slope of Taihang Mountain were studied based on a biomass survey. The results showed that the carbon contents in different organs of apricots ranged from to 447.3 to 488.1 g/kg. The carbon content of stems decreased significantly with stand age, whereas no significant differences in carbon content were observed among the roots, branches, and leaves of the apricot plantations with different ages. The carbon content in the soil layer (0-100 cm) increased significantly with increasing stand age, but decreased with increasing soil depth (P < 0.05). The carbon storage in the arbor layer, soil layer, and whole ecosystem of the apricot plantations was obviously age dependent. The values of total carbon storage in the 4-, 8-, 12-, and 16-year-old apricot plantation ecosystems were 27.810, 72.647, 82.450 Mg/hm² and 102.336 Mg/hm², respectively. The carbon storage in the soil layer accounted for >90.1%of the carbon storage in the apricot plantation ecosystem, which was accumulated at higher levels in the 0-40 cm soil layer. The carbon storage and distribution patterns in the apricot plantations varied obviously with the stand age. In addition, carbon storage allocation increased in the arbor layer but decreased in the soil layer with increasing stand age. Our results suggested that the soil layer was the major carbon pool, and also impliedthat the plantation ecosystems at these stand ages could accumulate organic carbon continuously. Quantifying carbon storage and distribution patterns of apricot plantationscould help design sustainable forest management strategies for achieving its potential in mitigating climate change.
