| 英文摘要 | Sedimentary organic carbon (OC) in coastal areas can effectively document changes in climate and environment. In this study, multi-biogeochemical date from core XHB-5 in Xinghua Bay were analyzed to elucidate the primary factors influencing the origins and changes of buried OC over the past 5.5 k years. Constrained by the coupled delta 13C and C/N ratios, the sedimentary OC was a combination of terrestrial OC sourced from nearshore riverine input and marine OC, with minimal influence from the Changjiang River or muddy belt. A two-end-member mixing model based on OC isotopes indicated that terrestrial OC (63.3 +/- 7.8 %) was the predominant OC source during 5.5-3.6 cal. Kyr BP, whereas marine OC (60.6 +/- 5.1 %) has been the dominant contributor since 3.6 cal. Kyr BP. The downcore changes in the proportions of terrestrial OC and marine OC contents can reflect the evolution of the East Asian monsoon. However, the variation in terrestrial OC contents did not align consistently with East Asian summer monsoon records, potentially due to the influence of sediment grain size and sediment accumulation rate on the burial of OC. Furthermore, the increasing anthropogenic activities since 1.6 cal. Kyr BP may also have had a significant impact on terrestrial OC contents. |
