During the past five years, significant progress has been  achieved on the following programs:

  • Research on dynamic changes of the cryosphere in China
  • Geocryological and engineering problems along Highway 214, Qinghai–Tibet Plateau (QTP)
  • Studies on the interaction among permafrost, vegetation and the atmosphere on the QTP
  • Monitoring active layer processes on the QTP -Engineering geology on the trans-water project from
    the Yangtze River to the Yellow River: A western alternative
  • Pre-studies on geocryological engineering for construction of the Qinghai–Tibet Railway, from Golmud to Lhasa
  • Pre-studies of gas hydrates on the QTP

Important geocryological problems in China include:

  • Thermal stability of permafrost and the impacts of climatic change
  • Environmental engineering in the cold regions of China -Water resources at high altitudes and their roles in the formation and stability of water resources in western China

Recent major breakthroughs include:

  • Evidence of permafrost degradation in the eastern QTP
  • Establishment of a cryosphere database in the eastern QTP
  • Application of fracture mechanics in frozen soils
  • Construction of tunnels in alpine permafrost regions

Two important meetings were held:

  • The Chinese National Workshop on The Cryosphere and Global Change, 5–7 May 1995, at the Lanzhou Institute of Glaciology and Geocryology, Chinese Academy of Sciences 
  • The Fifth Chinese Conference on Glaciology and Geocryology, 18–22 August 1996, at Lanzhou University

Some recent major publications are:

  • Abstracts and Proceedings of the Chinese National Workshop on the Cryosphere and Global Change Cryosphere, first issue in 1995, second and third issues in 1996 and 1997
  • Proceedings of the Fifth Chinese Conference on Glaciology and Geocryology, two volumes
  • Assessment of Climate Change Impact on Snow Cover, Glaciers and Permafrost in China
  • Seasonally Freezing Halic Soils and Their Improvement: Utilization in the Hexi Corridor, Gansu, China
  • Permafrost Distribution Map of the Qinghai-Tibet Plateau
  • Mechanism of Frost Heave and Moisture Potential in Frozen Soils
  • Strength and Creep of Frozen Soil
  • Frozen Ground in China (in press)
  • Fracture Mechanics of Frozen Soils (in press)
  • Mechanism of Frost Heave and Moisture Potential in Frozen Soils (in English, in press)

Recent doctoral dissertations include:

  • Li Shuxun: Heat–Moisture Transfer in Frozen Soils
  • Chen Ruijie: Moisture Migration in Frozen Soils
  • Zhao Xiufeng: Frost Weathering of Rocks on the Qinghai–Tibet Plateau
  • Mi Haizhen: Temperature Field of Frozen Wall Rocks in the Dabanshan Tunnel, Qinghai-Tibet Plateau
