Atmospheric pollution for trace elements in the remote high-altitude atmosphere in central Asia as recorded in snow from Mt. Qomolangma (Everest) of the Himalayas

A series of 42 snow samples covering over a one-year period from the fall of 2004 to the summer of 2005 were collected from a 2.1-m snow pit at a high-altitude site on the northeastern slope of Mt. Everest. These samples were analyzed for Al, V, Cr, Mn, Co, Ni, Cu, Zn, As, Rb, Sr, Cd, Sb, Pb, and Bi in order to characterize the relative contributions from anthropogenic and natural sources to the fallout of these elements in central Himalayas. Our data were also considered in the context of monsoon versus non-monsoon seasons. The mean concentrations of the majority of the elements were determined to be at the pg g(-1) level with a strong variation in concentration with snow depth. While the mean concentrations of most of the elements were significantly higher during the non-monsoon season than during the monsoon season, considerable variability in the trace element inputs to the snow was observed during both periods. Cu, Zn, As, Cd, Sb, and Bi displayed high crustal enrichment factors (EF(c)) in most samples, while Cr, Ni, Rb, and Pb show high EF(c) values in some of the samples. Our data indicate that anthropogenic inputs are potentially important for these elements in the remote high-altitude atmosphere in the central Himalayas. The relationship between the EF(c) of each element and the Al concentration indicates that a dominant input of anthropogenic trace elements occurs during both the monsoon and non-monsoon seasons, when crustal contribution is relatively minor. Finally, a comparison of the trace element fallout fluxes calculated in our samples with those recently obtained at Mont Blanc, Greenland, and Antarctica provides direct evidence for a geographical gradient of the atmospheric pollution with trace elements on a global scale.

宁夏广武山铜矿特征及成矿规律

从宁夏广武山铜矿矿化特征分析成矿原因,试图找出成矿规律.在已有资料的基础上,研究了该地区含矿地层区域铜矿化特征.结果表明,该地区原生黄铜矿型铜矿的原生沉积和次生富集的发生与褪色带关系密切,形成似层状矿体.退色带中铜矿化是氧化-还原过渡带环境的产物,是成矿的有利部位.广武山地区寻找铜矿应注意研究相对应的有利地质成矿部位,可望有新的发现和突破.

关于龙安寺方丈庭园造园意图的考察

"龙安寺方丈庭园"是日本具有代表性的庭园,但其建造时期、建造者、建造意图都未有定论。本文认为此园是对中国五台山的描绘。自古以来五台山的文殊菩萨信仰非常兴盛,从8世纪开始有多位来自日本的高僧到访过五台山,并将佛像、绘画等带回了日本。以此为依据在13世纪绘制而成的"五台山文殊菩萨骑狮像",中央石峰的形态与"龙安寺方丈庭园"中央置石组群造型相同,可以推断"五台山文殊菩萨骑狮像"中的石峰是其描摹的原型。     

六盘山地区沥青结合料气候适应性研究

Development of time-variant landslide-prediction software considering three-dimensional subsurface unsaturated flow

An accurate landslide-susceptibility assessment is fundamental for preventing landslides and minimizing damage. In this study, a new time-variant slope-stability (TiVaSS) model for landslide prediction is developed. A three-dimensional (3D) subsurface flow model is coupled with the infinite slope-stability model to consider the effect of horizontal water movement in the subsurface. A 3D Richards' equation is solved numerically for the subsurface flow. To overcome the massive computational requirements of the 3D subsurface flow module, partially implicit temporal discretization and the simplification of first-order spatial discretization are proposed and applied in TiVaSS. A graphical user interface and two-dimensional data visualization are supported in TiVaSS. The model is applied to a 2011 Mt. Umyeon landslide in the Republic of Korea, and its overall performance is satisfactory.
