After liberation the study of seasonal snow and ice has begun progressively. The chief subject is how to prevent the disaster brought about by snow and ice, including the prediction of ice conditions and the protection against flooded ice in northern China on one hand, the engineering prevention of avalanche and drift snow in mountain regions on the other hand. Now the protection against flooded ice in Huang He has been supported by reservoir regulation. Applying earthwork to prevent avalanche is suited to Chinese conditions. Leading fence is an efficacious method for preventing snowdrift in the mountain regions. Both snow cover charts and river ice charts on the basis of records for more than 20 years were compiled. Certain achievements have been gained in the researches on the moving feature of snow drifting over varied landform, and on the ice action, affected by the cold wave, on engineering structure.

Since 1958, Glaciological researches were carried on in Qilian Shan, Tian Shan, Himalaya, Southeast Sizang and other mountains in west China and also Karakoram in Pakistan. The total glacierized area in west China is roughly estimated at about 56, 471 km², nearly a half of that in Central Asia. The snowline ranges between 3, 000 m (Altay) and 6, 200 m (south west Xizang). According to climatic conditions and physical properties (ice formation, ice temperature, heat and mass balance, ice movement, etc.), glaciers in Central Asia could be classified into three types : Continental type (Tian Shan, Qilian Shan, Kunlun Shan, northern slope of Himalaya and interior mountains of Qinghai-Xizang plateau), maritime type (southeast Xizang), and complex type (several longest valley glaciers in Karakoram, Pamir, Tian Shan, southern slope of Himalaya). From the 1950s to 1960s, glaciers were retreating, but in 1970s positive mass balance appeared in some glaciers, and snowline descended. The incomplete data from various sources, mailny by comparing aerial maps of 1960s with Landsat images of 1970s, show that a large part of glaciers are still receding, but the rate of reccession is obviously reduced and a small part of glaciers are clearly advancing.
