Characteristics, Influence of Cryosphere Disaster and Prospect of Discipline Development
(2.School of Environmental and Geographical Sciences, Shanghai Normal University , Shanghai, China 200234)
【Abstract】Cryosphere disasters include continental cryosphere disaster, marine cryosphere disaster and aerial cryosphere disasters, which are widespread and have caused serious loss and influence. With the increasing frequency and intensity of cryosphere disasters caused by climate warming, the cryosphere region faces severe challenges in poverty eradication, climate change mitigation and adaptation, and sustainable economic and social development. Early cryosphere disaster studies mainly focus on the disaster events, disaster effects, and prevention of single disaster, concentrating on avalanche, glacial lake outburst, and glacier debris flow disasters. Since the 1980s, the research scope of cryosphere disaster science is gradually expanding, some cryosphere disasters such as permafrost disasters, sea ice disasters, and ice jam/flood disaster have received extensive attention and further research. With the establishment and improvement of cryosphere science system in the last decade, the discipline system of cryosphere disaster science is developing and achieving significant progress in the research on cryosphere disaster risk, impact and adaptation. Based on previous studies, this paper elaborates on the connotation of cryosphere disaster science, reviews the spatiotemporal characteristics of cryosphere disaster and its comprehensive influence, and then puts forward some suggestions on the construction and development of cryosphere disaster science in the future.
