The three former geo-science institutes of the Chinese Academy of Sciences (CAS) at Lanzhou, i.e., Lanzhou Institute of Glaciology and Geocryology, Lanzhou Institute of Desert, and Lanzhou Institute of Plateau Atmospheric Science, have been reorganised into a new institute in June, 1999, which is called the Cold and Arid Regions Environmental and Engineering Research Institute (CAREERI), CAS.


The major research areas of the new institute are glaciology, geocryology, cold regions engineering, desert and desertification, hydrology and land resources in cold and arid regions, plateau atmospheric science, and ecology and agriculture in cold and arid regions. Director of the new institute is Academician Cheng Guodong.

To provide an opportunity for scientists and engineers to discuss and exchange their achievements and experience in cold regions engineering and to accelerate the great development of Western China, the Fourth International Symposium on Permafrost Engineering was held on 21-23 September 2000 at Lanzhou, China, organised and sponsored by the Chinese Society of Glaciology and Geocryology, CAREERI, Permafrost Institute of the Siberian Branch, Russian Academy of Sciences, Heilongjiang Institute of Cold Ground Construction Science, Communication Department of Tibet, Communication Department of Qinghai Province, the First Survey and Design Institute of Highway, Ministry of Communication of China, Western Branch of Railway Science Institute, Ministry of Railway of China, the First Survey and Design Institute of Railway, Ministry of Railway of China, and Chang’an University. The proceedings are published in English. Please contact Prof. Zhu Yuanlin for information to purchase the proceedings. The Qinghai-Tibet Railway is going to be built on the Qinghai-Tibet Plateau. The length of this railway is about 1100 km, among which about 560 km will be across permafrost terrain. Large-scale investigation and research dealing with the permafrost engineering problems of designing and constructing this railway will be started very soon. Experts and scientists from all over the world who are interested in the science and technology of permafrost engineering and other problems are welcome to take part in the scientific research programme for construction of this railway.
