An active layer monitoring site was established in the Yituli River basin, northeast China, in 1997 based on the ITEX/CALM protocol. Two boreholes for monitoring ground temperatures were drilled at this site to depths of 13 and 40 m .
The Lanzhou Institute of Glaciology and Geocryology (LIGG) is undertaking a program for research and monitoring of the cryosphere of the Qinghai–Tibet Plateau. This includes a model of the response of plateau permafrost to climate change and is supported by a GIS and an engineering–geological database of permafrost along the Qinghai– Tibet highway. The present processes of the active layer in permafrost areas of the plateau are being investigated.
In 1997 LIGG, in cooperation with the Japanese GAME National Subcommittee for GAME/Tibet (GNSGT), set up seven observational sites for investigating the variation of ground temperature and moisture in the active layer along the Qinghai–Tibet highway. A test site for observing methane flux has been established in the permafrost region in the Huashi Valley of Qinghai Province.

A major national research progam on the interaction among atmosphere, vegetation and permafrost on the Qinghai–Tibet Plateau will be started next year.
Two books, An Assessment of Climate Change Impact on Snow Cover, Glacier and Permafrost in China and Seasonally Freezing Saline Soils and Their Improvement: Utilization in the Hexi Corridor, Gansu, China, were published. Three additional books, Frozen Ground in China, Mechanism of Frost Heave and Moisture Potential in Soil and Fracture Mechanics of Frozen Soil, will be published in 1998.
