Abstract： After nearly 20 years of development, the Yulong Snow Mountain National Field Observation and Research Station for Cryosphere and Sustainable Development, Chinese Academy of Sciences has built a field comprehensive observation system and data online visualization platform of temperate glacier and environment integrating observation, research, demonstration, and service. Based on the long-term positioning monitoring of temperate glaciers and the environment, and focusing on key scientific issues related to sustainable development in temperate glacier areas, this study deeply analyzes the mechanism of changes in temperate glaciers, reveals the hydrological, microorganisms, and climatic effects of temperate glacier change, evaluates the effectiveness of temperate glacier tourism services and integrated risk of glacial lake outburst disasters, and provides scientific and technological support for regional sustainable development.

Abstract： Cryospheric chemistry is a new discipline and one of important branch of cryospheric science. Pollutant emissions from anthropogenic activities have greatly altered the status of chemical components in the cryospheric environment since the Industrial Revolution. When this scenario is coupled with the rapid shrinkage of cryosphere under global warming, both anthropogenic activity and global warming have cooperatively influenced the biogeochemical cycling in the cryosphere and even on a global scale, which results in significant effects on climate and environment. In this paper, firstly, the role of cryospheric chemistry in the cryospheric science is introduced, and the discipline framework and research focuses of cryospheric chemistry are summarized. Secondly, the coupling relationship among cryospheric chemistry and climate/environmental changes, and anthropogenic activities, with emphasis on this relationship in the research field of global change, was exemplified. Lastly, we summarize a review and prospect of hot topics in the current research of cryospheric chemistry. The rapid development of cryospheric chemistry will provide important scientific and technological support for tackling the climate and environmental issues that challenge human survival and development.

Abstract：基于祁连山西段老虎沟冰川站2010年1月至2011年10月大气颗粒物观测数据，通过HYSPLIT-4后向轨迹模式，使用轨迹聚类分析、潜在源贡献因子法(PSCF)和浓度权重轨迹法(CWT)，研究了老虎沟地区不同粒径颗粒物（PM10、PM2.5和PM1）传输路径及潜在源区的分布。结果表明：① 影响研究区的气流轨迹主要来自偏西方向，夏季还受到偏东气流方向的影响，3类颗粒物质量浓度存在显著的季节变化，表现为春、夏季节高、秋冬季节低的特点。② PSCF分析显示，春季颗粒物浓度高值与塔里木盆地东部和河西走廊西部等干旱半干旱地区沙尘向下游传输关系密切，夏季研究区颗粒物浓度高值的形成主要受到偏西方向的塔里木盆地周边、新疆北部、河西走廊西部等地区，以及研究区偏东方向的内蒙古西部、河西走廊、宁夏，甚至陕西西部等地区共同影响。③ 春季CWT高值区分布在研究区西北和偏西2个方向，夏季CWT高值除了偏西方向上贡献，还有来自偏东方向河西走廊等地区的贡献。
