LIU Rui1,2,3,QIN Jungan4(1.School of Earth Science and Engineering,Nanjing University,Nanjing 210093; 2.Key Laboratory of Marine Hydrocarbon Resources and Environmental Geology,Ministry of Land and Resources,Qingdao 266071; 3.Qingdao Institute of Marine Geology,Qingdao 266071; 4.Zhanjiang Branch Corporation of COONC,Zhanjiang 524000)  
The HMD Core(29°59.064′N、121°21.754′E) was collected near the Hemudu Civilization site at Ningshao Plain,the southern bank of Hangzhou Bay.The core is 45.3 m long with clay and silt as its main lithological components.The results of grain size,C/N ratio,organic carbon isotope(δ13CTOC) value and pollen analysis reveal the sedimentary environmental changes and paleoclimatic evolution stages in Ningshao Plain since LGM.It also shows that,the main organic source of HMD Core was from endogenous water plants,and the δ13CTOC values variation was mainly controlled by the change in atmospheric CO2 pressure.It is a good response to global climatic changes.
