ESI高影响论文揭示的北极自然科学研究特点

在全球气候持续变暖背景下,北极地区冻土退化、冰川退缩、海冰减少等导致了一系列的生态环境问题,同时也使得资源勘探开发与国际新航道开通成为可能,北极地区的重要性日益凸显.依据2009—2019年6月期间有关北极研究的408篇ESI高影响论文,对发文量、主要作者、研究机构、国家、研究方向等字段进行分析,从自然科学角度,宏观而...

ESI top papers reveal the characteristics in Arctic natural science research

Climate warming is amplified in the Arctic and accompanied by sea ice decline，which makes it possible for resource exploration and opening new sea channels. The importance of the Arctic region is becoming increasingly prominent. With the aim to understand the most influential research forces and fields in Arctic research，to provide the most comprehensive analysis of scientific research information，and to reveal the existing problems in Chinese current research，408 ESI top papers on Arctic research in the last decade were analyzed，including number of papers，authors，research institutions，countries and research areas. It is found that the United States dominates the Arctic research （number of papers，authors，institutions，funding funds）.The Arctic research fields include sea ice and oceans，organisms and typical ecosystems （adaptation and protection of biodiversity，boreal forests，tundra，microorganisms），glacier retreat and permafrost degradation，atmosphere，weather and climate system and other related fields. A great number of studies characterized by using large data and model operation，but “uncertainty” is common in all the fields. China conducts Arctic research in a cooperative，participatory，periphery-related and micro-entry manner. There are multiple constraints for China to conduct Arctic research. China may take advantage of the existing achievements in cryosphere research，actively participate in all fields of arctic research and data sharing，and focus on the impact of Arctic climate on mid-latitude regions to provide support in hazards prevention and mitigation，and thus improve ecological environment in China as well.
