摘要The GDGT distribution patterns provide evidence that they might be an indicator for certain environmental parameters. Proxies based on GDGTs are increasingly being utilized in palaeoclimatology to reconstruct palaeoenvironmental parameters. Core sediments collected from the mud area of the central South Yellow Sea were measured for TOC, delta C-13, GDGTs, and related indicators (BIT, CBT/MBT, etc.) to determine palaeoenvironmental variations in the South Yellow Sea during the last glacial-interglacial cycle. The results reveal: Though the input of aquatic plants in the study area decreased slightly from 43000 aB.P. to 33370 aB.P., material source remained largely unchanged, there was marine input (mainly aquatic low bacteria algae) rather than any terrigenous input. The climate warmed during this period. Seawater was alkalescent, and the alkalinity increased as the sediment samples became younger. Alkaliphiles were the dominant species, and the amount of alkaliphiles increased overall. What's more, the South Yellow Sea was in a cooling climate, which was in accordance with the global change in the last glacial period. Sea surface temperature (SST) was more affected by the last glacial period than mean annual air temperature (MAAT), it means that SST was more sensitive to climate changes; over the course of the period, both the early stage and the late stage were characterized by the stabilization of environmental change, whereas the middle stage was characterized by diverse environmental fluctuations.
