摘 要：According to the first recommendation of the International Symposium on Mountain and Arid Land Permafrost（Ulaanbaatar,2001）,an international team experts from China,Kazakhstan,Mongolia and Russia are required to prepare a uniform map of Central Asian *** tasks of the IPA working group on mapping and modeling of mountain permafrost（ICOP,2003） are to analyze the experience of permafrost map in the different countries and to develop uniform legend for compiling Central Asian permafrost *** principles and methods of permafrost classification and mapping in China,Kazakhstan,Mongolia and Russia lead to some difficulties in compiling the uniform ***,initial data for the map are very different in every mountain regions of Central *** objectives of this paper are to analyze present state of permafrost mapping in Mongolia and to put forward for discussion the proposed draft of unified legend for compiling Central Asian permafrost *** state of permafrost mapping in *** a result of Joint Russian and Mongolian geocryological expedition in 1967-1971,*** et *** permafrost map of Mongolia（1:1500000）,which shows distribution of permafrost and cryogenic *** on latitudinal zones and altitudinal belts of permafrost distribution,the permafrost zone of Mongolia is divided into geocryological areas of sporadic（1%）,scattered islands（1-5%）,islands（5-40%）,discontinuous（40-80%） and continuous（80%） permafrost by its *** mapping of permafrost in Mongolia has been carried out by *** on the basis of determining temperature regime of permafrost *** parameters of ground temperature regime are mean annual ground temperature and geothermal *** order to obtain the parameters,the author carried out geotemperature measurements in more than 400 boreholes with depths of 10-200 m which are located mainly in Hovsgol,Burenkhan,Erdenet,Argalant,Nalaikh and Baganuur *** on factor an
