- 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.

- 鄱阳湖沙化土地生态治理技术研究与示范
- 作者： 郑林 曹昀 丁明军 胡启武 李晓峰 贾玉连 詹选怀 李海涛 梁涛 来源：中国科技成果 年份：2015 文献类型 ：期刊 关键词： 政府部门 示范 土地面积 滨湖地区 沙化治理 鄱阳湖地区 沙化土地 生态治理技术
- 描述：鄱阳湖地区作为南方沙化的典型分布区，沙化土地面积3.89万公顷，主要分布于彭泽、湖口、都昌、星子、永修、新建等滨湖地区。当前，鄱阳湖沙化正以3～5米/年的速度扩展，甚至出现了“沙进人退”的状况，严重影响了当地居民的生产和生活，已引起科研机构和政府部门的高度重视。近几十年来，一些学者就鄱阳湖沙化土地的形成演化、景观结构、植被演替等方面进行了研究，但对鄱阳湖地区沙化土地演化过程、机理以及与北方荒漠化异同等问题目前尚没有形成明确、统一的结论，在沙化治理方面尽管也开展了一些相关工作，但还未探索出适宜于本地区成熟的沙化治理技术与模式。

- 鄱阳湖沿湖居民血吸虫病血清流行病学调查分析
- 作者： 钟子静 曾小军 姜唯声 胡位陈 兰炜明 张智珠 高晓晖 谢峰 葛军 吕尚标 来源：实验与检验医学 年份：2009 文献类型 ：期刊 关键词： 分析 流行病学 血清 血吸虫病
- 描述：目的了解鄱阳湖区血吸虫病二类疫区居民抗体变化规律。方法用Kato-Katz和IHA法对居民进行病原学和血清学检查。结果该地居民血吸虫平均感染率和抗体阳性率分别为6.19%和26.67%,不同年龄组全体人群血吸虫感染率和抗体阳性率均随着年龄的增大而升高,分别在40～和50～岁组达到最高;不同年龄组全体人群感染度EPG和抗体滴度倒数的几何均数(GMRT)年龄变化规律也随着年龄的增大而升高,均在40～岁组最高,后逐渐下降。男性居民血吸虫平均感染率和抗体平均阳性率均高于女性。结论血吸虫病血清流行病学调查是判断一个地区血吸虫病流行现状的敏感指标,可作为血吸虫病流行病学监测的工具之一。
