基于Landsat-8OLI的鄱阳湖叶绿素a浓度定量反演

作者： 黄灵光 方豫 张大文 林联盛  来源：江西科学 年份：2016 文献类型 ：期刊 关键词： Landsat  鄱阳湖  模型  8  叶绿素a  OLI 

描述：Landsat-8 OLI数据的应用越来广泛、成熟,但尚未见诸在水质监测,尤其是叶绿素a浓度监测方面的应用。以叶绿素a作为参数,结合准同步的实测数据,通过在鄱阳湖的应用案例,研究、探讨利用Landsat-8 OLI卫星数据对湖泊叶绿素a遥感反演的可行性和相关潜力。根据研究,鄱阳湖与实测叶绿素a相关性最高的是波段B4(红波段),Pearson相关系数为0.916,并由此而选择B4作为构建模型的波段组合,建立线性回归、对数、指数、乘幂、二次多项式等五种回归模型,通过R2系数对比,显示二次多项式回归模型为最佳模型。经实测点验证,该模型能较好地反演出鄱阳湖的叶绿素a浓度。

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.
