Abstract

A 3.12-m sediment core named HMD was retrieved near the Hemudu archaeological site to decode the rice farming history and its connection to the environment change at the site since mid-Holocene. Microfossil results together with core lithology indicated a brackish supra-tidal flat deposition prior to ca. 6500 years ago, on which the Hemudu people settled. A desalinized environment indicated by abundant aquatic herbs and declined dinoflagellate at ca. 6500–6200 cal yr BP would have favored human occupation and rice farming assisted by clearing and firing. This then followed by a significant increase of Pinus pollen and fern spores, suggesting enhanced fluvial processes possibly under a cooler..
