| The current Northern Circumpolar Soil Carbon Database did not include organic
carbon storage in permafrost regions on the Qinghai–Xizang (Tibetan) Plateau
(QXP). In this study, we reported a new estimation of soil organic carbon
(SOC) pools in the permafrost regions on the QXP up to 25 m depth using a
total of 190 soil profiles. The SOC pools were estimated to be
17.3 ± 5.3 Pg for the 0–1 m depth, 10.6 ± 2.7 Pg for the
1–2 m depth, 5.1 ± 1.4 Pg for the 2–3 m depth and
127.2 ± 37.3 Pg for the layer of 3–25 m depth. The percentage of SOC
storage in deep layers (3–25 m) on the QXP (80%) was higher than that
(39%) in the yedoma and thermokarst deposits in arctic regions. In
total, permafrost regions on the QXP contain approximately 160 ± 87 Pg
SOC, of which approximately 132 ± 77 Pg (83%) stores in
perennially frozen soils and deposits. Total organic carbon pools in
permafrost regions on the QXP was approximately 8.7% of that in northern
circumpolar permafrost region. The present study demonstrates that the total
organic carbon storage is about 1832 Pg in permafrost regions on northern
hemisphere. |
