1977年,南通博物馆在江苏中部海安县青墩,发掘了一处新石器时期的遗址,1978、1979年,南京博物院继续主持发掘,先后出土了大量陶器、石器、骨器和玉器;发现丰富的动物化石(亚化石)及一批古人骨架。有关单位对遗址的文化层进行了划分和研究,采集古土样品做孢子花粉分析,并对埋藏的古树根做放射性碳的绝对年龄测定。本文以孢粉分析为依据,结合其它资料,推证新石器时期江苏青墩古人生活的地理环境及全新世中、晚期自然环境的变化。
In 1977, the Nantong Museum unearthed a Neolithic site in Qingdun, Haian County, central Jiangsu Province. From 1978 to 1979, the Nanjing Museum continued to host excavations and unearthed a large number of pottery, stoneware, bone implements and jades; Animal fossils (fossils) and a group of ancient skeletons. The relevant units of the cultural layer of the site were divided and studied, collecting samples of ancient soil spores pollen analysis, and the ancient tree roots buried radiocarbon absolute age determination. Based on the sporopollen analysis and other data, this paper deduces the geo-environment of the Qingdun ancient life in the Neolithic period and the changes of the natural environment in the middle and late Holocene.
