鄱阳湖流域史前人类遗址时空分布及其环境响应
作者: 徐佳佳 贾玉连 马春梅 朱诚 吴立 李育远 王鑫浩  来源:地理学报(英文版) 年份:2016 文献类型 :期刊 关键词: expanded  northward  geographic  records  环境响应  鄱阳湖流域  climatic  ancient  Holocene  southeast 
描述:The temporal-spatial geographic distribution of archaeological sites and its feature between 10.0–2.8 ka BP(ka BP= thousands of years before 0 BP, where “0 BP” is defined as the year AD 1950) were determined, based on GIS spatial analysis in the Poyang Lake Basin. The relationship between geographic distribution of sites of different periods under subsistence existence of ancient civilizations, climate and environmental change was investigated. The results revealed numerous archaeological sites of the Neolithic Age(10.0–3.6 ka BP). The sites were mainly located in the northern part of the Poyang Lake Basin, a hilly and mountainous area with many river terraces suitable for the development of human civilization. The number of archaeological sites rapidly increased during the Shang and Zhou dynasties(3.6–2.8 ka BP) and spread widely on the floodplains of the middle and lower reaches of Ganjiang River and onto the west, south, and southeast beach areas of the Poyang Lake. Holocene records of climate change suggested that it was possible that climate fluctuations had a great impact on human evolution in the study area. Before 3.6 ka BP, westward and northward expansion of Neolithic cultures in the Poyang Lake watershed occurred under the background of climate amelioration(becoming warmer and wetter). The ancient people lived in the hilly areas with high elevation. The simple mode of a fishing and gathering economy was mostly suited to this area in the early Neolithic Age. The scope of human activities was expanded and cultural diversity developed in the late Neolithic Age. However, with population growth and increasing survival pressure in a dry-cold climatic stage after 3.6 ka BP, this simple living mode had to be abandoned, and various forms of economy, the majority being agriculture, were developed on flood plains of the lower reaches of numerous rivers around Poyang Lake. This promoted flourishing of the Bronze culture of South China.

描述:通过对2011年鄱阳湖及其主要入湖河流(赣江、抚河、信江、修水及饶河)15个湿地土壤样品中δ13C及δ15N的测定,分析探讨了鄱阳湖及其主支流湿地土壤有机质和氮素来源、结果表明:鄱阳湖湖区湿地土壤中总有机碳(TOC)的含量在0.45%1.58%之间,总氮(TN)含量变化范围为0.06%0.17%;各入湖河流TOC含量为0.41%1.18%,TN含量在0.05%0.13%之间.鄱阳湖湖区湿地土壤有机质δ13C及δ15N变化范围分别为-28.35‰18.58‰和3.27‰6.84‰;各入湖河流湿地土壤δ13C和δ15N分别为-25.93‰-22.66‰和2.97‰5.41‰.有机质来源分析表明:除湖口处主要来源于C4植物外,鄱阳湖区及其入湖河流湿地土壤有机质的主要来源是C3植物.湖区湿地土壤氮素来源分析表明吴城处主要受农业化肥使用的影响,而其他采样点湿地土壤有机质氮素主要来源于生活污水;入湖河流湿地土壤氮素来源较复杂,生活污水、化肥及工业污水是其主要来源.
