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.

鄱阳湖五河尾闾沉积物表层重金属分布及潜在生态评价

作者： 张力薇 段茂庆  来源：北京石油化工学院学报 年份：2016 文献类型 ：期刊 关键词： 沉积物  风险评价  重金属 

描述：为掌握五河尾闾沉积物表层重金属的污染特征,选取6个典型代表性区域沉积物表层样品,并对6种重金属进行了测定分析。结果表明,沉积物中6种重金属Cu、As、Pb、Cr、Cd和Zn的质量分数范围分别为24.62~72.19、5.65~17.57、19.93~42.92、36.41~53.11、0.56~2.14、7.06~15.43mg/kg;库区沉积物表层重金属存在一定程度污染,除Zn外,其余金属元素均已超过鄱阳湖背景值。地累积指数法和污染指数法分析表明,Cu与Cd是主要污染因子,各元素污染程度:Cu>Pb>Cd>Cr>As>Zn,各重金属元素呈正相关,具有相似迁移过程的规律与污染来源。Hakanson潜在生态风险指数法评价与污染程度评价结果基本一致,Cd达到较重风险水平,其余元素在各断面都处于中度风险水平。
