Abstract： The cryosphere is closely related to climate change, human engineering activities and social and economic development. Each element of cryosphere has significantly different influence characteristics on engineering. Disasters by glaciers, snow cover, and sea (river and lake) ice will mainly affect the construction, safe operation, and serviceability of engineering. Frozen soil is a special foundation soil for engineering structures, thus freezing-thawing disasters and thermal and mechanical stability change of frozen soil will directly affect the stability of engineering. As global change, the elements of cryosphere change and its hydrological and ecological environment, surface process changes have significant influence on engineering, thus it is needed to strengthen the relationship research between the engineering construction and safety operation and the environmental factors change. In addition, engineering security technology is also needed to be more comprehensive to consider the influence of climate and environment changes. Therefore, climate and environmental change will become an important factor to be considered in the construction, safe operation, and serviceability of engineering in the regions of cryosphere in the future. At the same time, the Belt and Road infrastructure construction not only brings opportunities to cryosphere engineering, but also faces greater challenges.
