Abstract:: Above and underground biomass and allocation of carbon storage across an age-sequence of five secondary stands (18, 20, 25, 38 and 42 years old) in Pinus tabulaeformis forest in Taiyue Mountain of Shanxi were studies. The results showed that C contents in above and belowground components in the 18, 20, 25, 38 and 42 years old Pinus tabuliformis forests were 0.411 2～0.556 0 g/g and 0.424 8～0.532 8 g/g, respectively. Biomass in above and underground increased with age, and C storage in components had positive relationship with biomass. C storage in total aboveground biomass was 38.18 t/hm², 42.28 t/hm², 56.64 t/hm², 86.36 t/hm² and 95.74 t/hm², respectively, and it in total belowground biomass was 8.58 t/hm², 8.46 t/hm², 8.92 t/hm², 19.92 t/hm² and 38.70 t/hm², respectively. Stem is the most important carbon sink, with the largest carbon storage, followed by root stump, live branches, and the lowest C storage is in the bark, accounting for 30.90%～54.70%, 11.93%～28.41%, 8.55%～15.77% and 0.45%～0.88% of total C storage, respectively. Ratios of aboveground C storage to belowground C storage in five ages stands decreased rapidly from 0.22 in 18 years old stand to 0.16 in 25 years old stand. Capacity of carbon storage potential in Pinus tabuliformis forest increased with age, the large C sequestration potentials were observed in the maturing stands with the ages ranging from 25 years to 42 years
