鄱阳湖浅碟湖泊沉水植物冬芽的分布及对植食水鸟的食物贡献
作者: 张笑辰 秦海明 金斌松 陈家宽 吴建东 刘观华 马志军  来源:生态学报 年份:2014 文献类型 :期刊 关键词: 浅碟湖泊  分布  鄱阳湖  食物  冬芽  沉水植物  植食性水鸟 
描述:沉水植物的冬芽是植食性水鸟在越冬期的重要食物。鄱阳湖是长江中下游地区极为重要的水鸟越冬地,了解沉水植物冬芽的空间分布及其对越冬植食性水鸟的食物贡献可为水鸟保护提供科学依据。2012年10月和2013

鄱阳湖国家级自然保护区白鹤、东方白鹳和小天鹅种群数量与分布
作者: 朱奇 刘观华 曾南京 吴建东 金杰锋 詹慧英  来源:湿地科学与管理 年份:2012 文献类型 :期刊 关键词: 数量  分布  白鹤  东方白鹳  鄱阳湖国家级保护区  小天鹅 
描述:分布进行了监测与研究,结果表明这3个物种的数量一般都在12月达到最高,而10月由于候鸟刚刚迁来以及翌年3月已有部分候鸟迁离,故这2个月份鸟类数量相对较少。保护区的9个湖泊中,沙湖是白鹤、东方白鹳和小天鹅

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.
