对江苏省苏州绰墩遗址马家浜期的文化层展开孢粉分析研究,结合绰墩遗址前期的研究成果,可以推论:全新世以来的气候变化,对长江三角洲新石器时期人类生存与发展,影响甚微。预测未来数百至数千年间冰期的气候事件,也不会对这一地区高速发展的经济带来威胁。孢粉分析的结果再次证明长江下游是中国稻作起源地之一,但在马家浜文化期,绰墩遗址可能存稻作活动的间断。 Based on the analysis of the sporopollen in the cultural layer of Majiabang period in Chuodun Site of Suzhou in Jiangsu Province and the research results of Chuodun site in the early period, it can be inferred that the climate change since the Holocene had significant impact on the survival and development of human beings in the Neolithic Period in the Yangtze River Delta, Little effect. Predicting climatic events over the next hundreds to thousands of years will not pose a threat to the fast-growing economy in the region. Pollen analysis again proved that the lower reaches of the Yangtze River is one of the origins of rice in China, but during the Majiabang culture, Chuodun site may contain intermittent rice activities.
