| 摘 要： | 本文基于长江中游江汉—洞庭盆地18个钻孔岩性、沉积特征及年代数据,结合研究区考古遗址点时空分布特征,恢复研究区全新世以来水文环境演变过程,并探讨了区域水文环境演变的成因机制及其与人类活动的关系。结果表明,受东海海面上升和泥沙淤积等因素影响,距今11.5—5.5 ka,长江中游地区河湖水位呈上升趋势,随着新石器文化的发展及稻作农业活动的增加,人类文化聚落自山前平原地带逐渐向盆地平原中部扩展;距今5.5—4.0 ka,长江中游河湖水位有所下降,新石器晚期的屈家岭—石家河文化迅速发展,聚落数量增多,平原腹地聚落比例增加;距今4.0 ka前后,河湖水位再次有所上升,洪泛过程加剧,可能是石家河文化快速衰落的主要原因。

| Abstract: | Based on the comprehensive analyses of 18 core profiles' sedimentary sequences and lithological characteristics in Jianghan-Dongting Basin of the middle reaches of Yangtze River and the spatial-temporal distribution of archeological sites in this area, we reconstructed the Holocene hydro-environmental evolution of the research area, and its relationship with human activities. The comparison reveals that in 11.5-5.5 ka BP, the water level of rivers and lakes in the middle Yangtze River presented a rising trend, concurrently, under the development of Neolithic culture and rice agricultural activities, human occupation extended from piedmont plain to inner basin plain in the research area. The water level fell in 5.5-4.0 ka BP, meanwhile, the number of human settlements of Qujialing-Shijiahe culture rapidly increased, especially in the inner basin plain. The water level rose again around 4.0 ka BP, and floods spread massively in this period, which led to the decline of Shijiahe culture. The main causes of hydro-environmental evolution in the research area are the fluctuation of sea level and the aggradation of fluvio-lacustrine sediments. |
