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.

鄱阳湖流域入湖径流时空变化预测
作者: 张静文 郭家力 刘佳 李英海 郭靖  来源:南水北调与水利科技 年份:2016 文献类型 :期刊 关键词: 径流变化  三峡水库  鄱阳湖  统计降尺度  气候变化 
描述:对鄱阳湖未来入湖径流变化的准确预测可为“后三峡”时期水资源调度决策提供理论依据。基于实测资料发现,三峡水库蓄水后,鄱阳湖入湖年径流及各调度期径流均不同程度减少。通过ASD(Automated Statistical Downscaling)统计降尺度方法将GCM(General Circulation Model)输出数据与新安江水文模型耦合,得到未来鄱阳湖流域“五河七口”的入湖径流过程。结果表明,未来年径流相比实测变化幅度更小,偏多和偏少交替出现;集水面积较大的赣江、抚河和信江对鄱阳湖径流变化的贡献最大;无论A2还是B2情景下,均是蓄水期变化幅度最大、枯水期最小,且各调度期的入湖径流变化程度比年径流更大。
