"青藏高原形成演化及其环境资源效应"研究进展

青藏高原是我国地学、生物学、资源与环境科学有特色的优势研究领域和难得的天然实验室.青藏高原研究对解决岩石圈地球动力学和全球环境变化有重要意义,对高原区域可持续发展也有广阔的应用前景.本项目选择青藏高原的典型地区为重点,特别注意从高原与毗邻地区的联系,以至从全球尺度探讨高原的各种过程,目标集中在大陆碰撞过程和高原隆升过程,以过程为主线贯通碰撞机制、环境变化和资源分布规律的研究;时间上着重新生代以来,在不同精细时间尺度上定量地描述碰撞和隆升的动态过程及环境变化.主要研究内容包括以下4个方面大陆岩石圈碰撞过程及其成矿效应;高原隆升过程与东亚气候环境变化;青藏高原现代表生过程及相互作用机理;青藏高原区域系统相互作用的综合研究.项目的实施紧密围绕预期目标,深入分析,加强学科交叉和综合研究,取得了如下主要研究进展和创新成果印度大陆与欧亚大陆初始碰撞时限;青藏高原南北缘山盆岩石圈尺度的构造关系;新生代高原北部重大的构造变形隆升事件序列;高分辨率气候动态过程及变化趋势;高原隆升对亚洲季风发展变化的影响;高原不同生态系统类型温室气体吸收与排放.同时,本文也论述了项目的实施在青藏高原研究的科学前沿及区域发展的国家需求等方面产生的影响和作用,并展望了青藏高原研究重要的前沿领域.     

Microparticle record in the Guliya ice core and its comparison with polar records since the last interglacial

Based on the study of oxygen isotope and microparticle in the Guliya ice core,atmospheric dust and environmental changes in the northwest Tibetan Plateau since the last interglacial were revealed.The microparticle record indicates that low dust load on the Plateau in the interglacial.Particle concentration increased rapidly when the climate turned into the last glacial and reached the maximum during the MIS 4.In the Last Glacial Maximum, however,the enhancement of microparticle concentration was slight,differing to those in the Antarctic and Greenland.On the orbital timescale,both the temperature on the Tibetan Plateau and summer solar insolation in the Northern Hemisphere had their impact on the microparticle record,but the difference in phase and amplitude also existed. Though having the same dust source, microparticle records in the ice cores on the Tibetan Plateau and the Greenland seem to have different significance.     

Millennial-scale climate change since the last glaciation recorded by grain sizes of loess deposits on the northeastern Tibetan Plateau

Whether climatic changes in high latitudes of the Northern Hemisphere since the last glaciation have effects on the Tibetan Plateau monsoon, and the variation characteristics of the Plateau monsoon itself are still not solved but of great significance. The 22-m high-resolution Ioess-paleosol sequence in the Hezuo Basin on the northeastern Tibetan Plateau demonstrates that the Plateau winter monsoon experienced a millennial variation similar to high latitude Northern Hemisphere, with cold events clearly correlated with Heinrich events but less for the warm events (Dansgarrd-Oeschger events). It may indicate that the climate system at high latitudes in the Northern Hemisphere had played an important role in both the Plateau monsoon and the high-level westerlies. On 10^4 year scale, there are two distinct anomalous changes, which are not found in the records from high latitude northern hemisphere, revealed by the loess grain size in the Hezuo Basin. One is that there was a considerable grain size increase at -36 kaBP, suggesting an abrupt enhancement of the Plateau winter monsoon at that time; the other is that, during 43--36 kaBP, the grain size decreased distinctly, indicating a notable weakening of the Plateau winter monsoon around that period. Both of the two anomalies suggest that the Tibetan climate may have been controlled by some other factors, besides the high latitude climatic changes in the Northern Hemisphere.

基于有限扩展优势关系的粗糙决策分析方法

针对基于扩展优势关系的粗糙决策分析方法的局限性，本文给出了一种新的基于拓展粗糙集的多属性决策分析方法。首先提出了有限扩展优势关系的概念；其次在有限扩展优势关系下得到知识的粗糙近似，给出了分类决策规则；第三，通过对比分析，证明了新方法的性能优于现有方法；最后通过一个实例验证新方法的可行性和有效性。     

神圣与内在:藏族农民洁净观念的文化诠释

结合田野调查资料和文献资料对藏族的洁净观念进行了初步的文化解读,认为宗教的神圣原则和内外有别的原则是藏族社会,特别是藏族农村社会具有普遍性的关于洁净的两个基本原则,把握这两个原则将有助于人们从一个新的角度理解藏族社会与文化。     

日本藏学发展简史——萌芽和创立时期(1812-1954)

日本的藏学研究在国际藏学界具有举足轻重的地位。根据日本藏学的发展特点,日本藏学史可划分为萌芽、创立、发展、繁荣四个阶段。本文对日本藏学的萌芽和创立两个阶段做了比较系统的疏理和考察。     

试论藏传佛教音乐审美

音乐审美是音乐美学最广泛的一个范畴,也是整个音乐美学中至关重要的问题。文章论及的是基于藏传佛教哲学——佛教人生观、世界观、宇宙观、价值观等之上形成的佛教音乐观,并由此试图揭示藏传佛教的音乐审美观。
