摘要
古文化演变与环境变化具有较强的相关性,受到广泛关注。基于考古学资料及相关地学证据,分析了岷江上游和成都平原史前文化的时空演变;讨论了全新世环境变化对甘青文化南迁、岷江上游干旱河谷新石器文化繁荣及随后迁至成都平原、以及古蜀文化繁荣与中断等古文化演变事件的影响。全新世中期的冷干气候变化促使了甘青地区部分人群迁入岷江上游;高温多雨的气候及地形、地质条件是史前人类聚居干旱河谷的主要原因;成都平原表生环境在4 800—4 600 a BP发生的变化很可能是古蜀文化兴起的重要条件,而地震成因的堰塞湖溃坝造成了古蜀文化的中断。
The close relationship between ancient cultural evolution and climate change has received widespread at-tention.In this paper,the spatial and temporal distribution of prehistorical evolution in the upper Minjiang River and Chengdu Plain are analyzed in accordance with the archaeological archives and geoscience data,and the impact of Holocene climate change on the events of ancient cultural evolution are discussed,including the southward spread of the Gansu-Qinghai culture,the rise and prosperity of the Neolithic culture in the arid valley regions and its subsequent shift of central settlements to the Chengdu Plain,the prosperity and interruption of the ancient Shu culture and so on.It is found that the cold-dry event in the mid-Holocene triggers the human immigration to the upper reaches of Minjiang River from the Gansu-Qinghai region;the climatic,topographical and geological conditions play a key role in the selection of prehistorical settlements in the arid-drought valley;the rise of the ancient Shu culture is most likely triggered by the supergene environment change in the Chengdu Plain during4800-4600aBP and its interruption is caused by a dam burst after palaeoearthquake.
