Abstract

In the context of climate change, research on frozen soils has attracted much attention in recent years, and numerous research papers have been published on these topics in the last decade. However, the present status and developmental trends in frozen soils research have not been reported systematically. Herein, a bibliometric analysis was conducted using 7,108 research papers on frozen soils published between 2010 and 2019. The results indicate that: (a) although the number of articles published increased from 432 in 2010 to 1,066 in 2019, the average number of citations per paper reached a maximum of 5.40 in 2014, and subsequently decreased to 2.99 in 2019; (b) China, the USA, and Canada ranked first to third in terms of total papers; (c) the most popular author keywords were boreal, tundra, Landsat, lakes, decomposition, dissolved organic carbon, permafrost thaw, and carbon cycle; and (d) the five most popular research topics in 2010–2019 were the characteristics and factors influencing frozen soils, the Arctic carbon cycle under the background of its complex environment, permafrost changes on the Qinghai–Tibet Plateau in the context of climate change, ancient frozen soils in various historical periods, and frozen soils in the Arctic.

2010-2019年冻土研究热点与趋势

在气候变化的背景下，冻土研究近年来备受关注，近十年来发表了大量相关研究论文。然而，冻土研究的现状和发展趋势尚未有系统的报道。本文对2010年至2019年发表的7108篇冻土研究论文进行了文献计量分析。结果表明:(a)论文发表数从2010年的432篇增加到2019年的1066篇，但平均被引次数在2014年达到最大值5.40次，随后在2019年下降到2.99次;(b)中国、美国、加拿大论文总量排名前3位;(c)最常见的作者关键词为北方森林(boreal)、苔原(tundra)、陆地卫星(Landsat)、湖泊(lakes)、分解(decomposition)、溶解有机碳(dissolved organic carbon)、冻土融化(permafrost thaw)和碳循环(carbon cycle);(d) 2010-2019年最热门的五个研究课题分别是冻土特征及影响因素、复杂环境下的北极碳循环、气候变化背景下青藏高原多年冻土变化、不同历史时期的古冻土和北极冻土。

期刊介绍： Permafrost and Periglacial Processes is an international journal dedicated to the rapid publication of scientific and technical papers concerned with earth surface cryogenic processes, landforms and sediments present in a variety of (Sub) Arctic, Antarctic and High Mountain environments. It provides an efficient vehicle of communication amongst those with an interest in the cold, non-glacial geosciences. The focus is on (1) original research based on geomorphological, hydrological, sedimentological, geotechnical and engineering aspects of these areas and (2) original research carried out upon relict features where the objective has been to reconstruct the nature of the processes and/or palaeoenvironments which gave rise to these features, as opposed to purely stratigraphical considerations. The journal also publishes short communications, reviews, discussions and book reviews. The high scientific standard, interdisciplinary character and worldwide representation of PPP are maintained by regional editorial support and a rigorous refereeing system.
