Geologic relationships and geochronology of the Cenozoic volcanoes and interbedded weathered mantles of Yulinshan in Qiangtang, North Tibet

The Yulinshan accumulations of volcanic rocks and interbedded weathered mantles provide a unique chance for studying the processes and environment of the formation of the planation surface in central Tibetan Plateau. Geochemical,⁴⁰Ar/³⁹Ar and K/Ar geochronologic investigations of the weathered mantles and high-potassium volcanic rocks reveal that the volcano-weathered mantle accumulations formed under arid or semi-arid subtropic environment in 30–24 Ma. The sole planation surface of the Qiangtang region finally formed in about 20 Ma.     

藏山羊放牧采食量及牧草干物质消化率测定方法的比较研究

春季同时用口罩法和AIA法两种方法测定高原型藏山羊成年公羊日采食牧草量和牧草干物质消化率比较研究表明,口罩法和AIA法测定藏山羊公羊日采食牧草量分别为1．1293±0．3496kg和1．2761±0．1670kg,二者差异不显著(P＞0．05);牧草干物质消化率相应分别为70．58±9．46％和73．82±2．43％,二者差异不显著(P＞0．05)．用AIA法测定牧草干物质消化率较用全收粪法简便、适用．     

关于林边新藏羊和边新藏羊产毛性状和体性状的比较

用林肯羊与边新藏羊(边区来斯特、新疆细毛羊和藏羊的杂交后代)进行级进杂交,其后代(林边新藏羊)的毛丛长度、细度、剪毛量、初生重、断奶重等育种指标均优于边新藏羊,而且其在育成时期的体重与边新藏羊接近.     

Elemental composition of aerosols collected in the glacier area on Nyainqêntanglha Range, Tibetan Plateau, during summer monsoon season

In order to investigate the elemental composition in atmospheric aerosols and its sources in the glacier area over the Tibetan Plateau (TP), seven totally suspended particle samples were collected continuously at the col of the Zhadang glacier (30°28′N,90°39′E,5800 m a.s.l.), Nyainqêntanglha Range, southern TP, from June to October 2006. Twenty-seven elements (Li, Be, B, Na, Mg, Al, K, Ca, Sc, Ti, V, Fe, Mn, Zn, Ga, As, Rb, Sr, Y, Cd, Cs, Ba, Tl, Pb, Bi, Th, U) were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The result indicates that the concentrations of most elements (especially crustal elements) are lower than values at the Nam Co Station during the same period of 2005, and also much lower than other sites in the TP such as Wudaoliang and Waliguan. This suggests that elemental compositions of aerosols in the Zhadang glacier area may represent the background levels of the middle/upper troposphere over the TP. Crustal enrichment factors (EFs) reveal that several elements (e.g. B, Zn, As, Cd, Pb and Bi) may have anthropogenic sources. The southern TP is mainly influenced by the summer Indian monsoon during the sampling period. Backward air mass trajectory analysis suggests that air masses in the region may originate from South Asia. Therefore, anthropogenic pollutants from South Asia may be transported by the summer Indian monsoon to the region which clearly affects the atmospheric environment in the southern TP during the summer monsoon season.     

初夏南亚高压中心经向位置年际变化的一个关键预测信号

基于欧洲中期天气预报中心的ERA-interim再分析资料,应用统计和动力诊断方法,分析了初夏南亚高压（SAH）中心位置年际变化规律及其与青藏高原东南部热源异常的联系.结果显示：初夏SAH中心位置具有显著的准6 a变化特征,但仅有其经向位置与初春青藏高原东南部（SETP）大气潜热活动存在显著的负相关关系;与偏强的初春SETP潜热活动相联系,异常的西风出现在青藏高原的南侧20°N附近,偏西风异常北侧的正涡度异常及其南侧的负涡度异常,加强了青藏高原附近的异常气旋以及印度次大陆半岛及印度洋上空的异常反气旋,这一异常环流形势可以从初春一直维持到初夏,不利于SAH向北移动,最终导致初夏SAH中心位置偏南;反之,初春SETP异常偏弱的潜热活动将以大致相反的物理过程,最终使得初夏SAH中心位置偏北.冬末春初的SETP潜热活动是预报初夏SAH中心经向位置年际变化的一个关键信号.
