摘要

HMD岩芯(29°59.064'N, 121°21.754'E)采集于杭州湾南岸宁绍平原河姆渡文明遗址附近。岩心长45.3 m，主要岩性为粘土和粉砂。粒度、碳氮比、有机碳同位素(δ13CTOC)值和花粉分析结果揭示了LGM以来宁绍平原沉积环境变化和古气候演化阶段。HMD岩心的主要有机来源为内源水生植物，δ13CTOC值的变化主要受大气CO2压力变化的控制。这是对全球气候变化的一个很好的回应。

SEDIMENTARY ENVIRONMENTAL EVOLUTION OF NINGSHAO PLAIN SINCE LAST GLACIAL MAXIMUM

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.
