摘　　要：在对东山村遗址地层进行AMSC14年代测定的基础上,通过微体遗存、孢粉、矿物表面微形态等分析认为,东山村遗址附近区域在马家浜文化之前为湖沼相沉积环境。地层中水生草本植物花粉的变化说明,在7.4ka B.P.之后,湖沼相水体开始变得不稳定,受气候变化影响明显;同时,遗址附近的植被种类和数量受人类活动影响较大。This paper discusses the Holocene sedimentary environment at the Dongshancun Site based on AMS14C dating and examination of micro fossil remains and particle size distribution. Samples were collected examined from various horizons at the Dongshancun site. Microfossil remains analysis shows that the Dongshancun site and its nearby regions had witnessed long-term development of a lacustrine environment before the onset of the Majiabang Culture. Spore-pollen data from other horizons suggest that the lake water regime became instable after 7.4kaB.P. Meanwhile, evidence of deforestation appeared in archaeological records due to the neolithic human activities.
