2012-2016年基于文献计量的全球冻土研究发展态势分析

冻土是冰冻圈的重要组成部分，其对全球变暖敏感且对工程稳定性影响显著，近年来全球科学家更多地关注这一研究领域。作为世界冻土大区的中国，对冻土学科的发展和动态尤其重视。本文基于文献计量的方法，对近五年（2012-2016）冻土学领域发表的SCI（E）/CPCI收录论文进行统计分析，得到该领域在全球的研究力量分布。同时，分别从冻土工程、冻土力学、冻土环境、冻土物理这四个方向加以区分，得到其不同机构与科学家论文发表情况。从论文产出的角度，宏观地反映了冻土科学在这五年中的发展脉络与国际影响力。这一工作可为全面了解近期该领域的研究发展动态提供数据参考。

Global development tendency of the frozen soil (permafrost) study based on bibliometrical analysis from 2012 to 2016

Study of frozen soil (including permafrost) gradually attracted the attention of global scientists, because frozen soil is an important component of the cryosphere, and it is sensitive to global warming and has the most effect on the stability of engineering. China, as one of the largest permafrost region, pays special attention to the development tendency of geocryology. Using the well-established bibliometrical analysis method, the papers published in the field of frozen soil (including permafrost) have been statistically analyzed, included in SCI(E)/CPCI bases from 2012-2016, and determined the order of scientific research strength in this field. The published papers can divided as frozen soil engineering, frozen soil mechanics, permafrost environment, and frozen soil physics. The results will present the development tendency and international influence of permafrost science during the past five years. It is useful for future development in this field.
