摘　　要：喜马拉雅山区的高海拔冰雪覆盖使主山体两侧形成下泄流,而在强太阳辐射的加热作用下,无冰雪覆盖的周边山体形成山谷风环流。上述两者叠加形成地气间的强烈交换过程。这种交换过程使得地面的物质和能量与北半球自由大气相联系,将青藏高原置于全球变化的背景中。在本文中作者介绍了中国科学院珠穆朗玛峰大气与环境综合观测研究站的建站背景及其研究喜马拉雅山地气相互作用过程中的作用,同时介绍了台站建设及其在该地区地气相互作用研究中所取得的初步研究成果。The mountains of Himalayas are the important channels for the mass exchange between surface layer of Northern Hemisphere and troposphere atmosphere. The mountains relate surface layer at- mosphere over the Tibetan Plateau and the above free atmosphere through many atmospheric circulation - systems including mountain-valley wind and glacier wind etc. Mr. Qomolangma is the highest peak in the world, and its nearby region is a representative case of mountains of Himalayas. Firstly the back ground of the establishment of the Atmospheric and Environmental Comprehensive Observation and Research Station on Mr. Qomolangma, Chinese Academy of Sciences （AECORSQ, CAS） and the role of the station in the study of the atmosphere-land interaction over Himalayas area was introduced in this paper. Then the preliminary observational analysis results, such as the characteristics of air temperature, pressure, air humidity, wind speed and wind direction, the structure of the Atmospheric Boundary Layer （ABL）, the atmospheric turbulent characteristics and the energy exchange between the land surface and surface layer atmosphere, were shown. The instruments layout of the AECORSQ, CAS was also given here.
