| Abstract | Delta C-14 values were measured from tree-rings (1948-2018) of Pinus tabuliformis Carr. that grew at the Shangdianzi (SDZ) regional background site in China. The objectives of this study are to establish a record of atmospheric Delta C-14, and to evaluate the influences of Chinese atmospheric nuclear tests and fossil carbon emissions on atmospheric Delta C-14 variations. The SDZ tree-ring Delta C-14 values are negative before 1956, and increase dramatically in response to global atmospheric nuclear tests, with a peak value of 844.0 +/- 4.2 parts per thousand in 1964. After the Partial Test Ban Treaty in 1963, the Delta C-14 values at SDZ decrease exponentially during 1964-2018. The half-life of the Delta C-14 decrease was protracted by approximately 2.7 yr during 1964-1984, due to Chinese atmospheric nuclear tests as well as Chinese forests as a carbon source during that period. Massive fossil carbon emissions in China lead to the SDZ decrease rate that is about 1.8 parts per thousand yr(-1) faster than that for the Northern Hemisphere background region during 2000-2010. SDZ Delta C-14 since 2000 show strong negative correlations with fossil carbon emissions from the Beijing-Tianjin-Hebei (BTH) region (r(2) = 0.954) and China (r(2) = 0.950), and a 1%o decrease in SDZ Delta C-14 indicates an increase of 2.3 +/- 0.2 Mt C and 23.3 +/- 1.7 Mt C fossil carbon emissions from the BTH region and China, respectively. |
