摘　　要：利用国外博、硕士论文数据库PQDT,对美国和加拿大地区研究北极主题的博士学位论文进行收集,并将收集到的学位论文按照各年文献量、授予学位机构、学科和关键词等方面进行文献计量分析。通过分析得到结论:美加北极主题的博士学位论文稳步增长;美加环北极机构是北极研究的主要机构;地质学、大气学、生态学、海洋学是美加北极研究的优势学科;海洋、岛屿、气候成为美加北极研究的焦点。Based on the collection of dissertations on Arctic research in USA and Canada from the database of PQDT, a bibliometric analysis has been conducted, including chronological distribution, degree-granting institutions, subjects and keywords. Some conclusions has been made that doctoral dissertations on the theme of arctic are growing steadily year by year; those institutions around Arctic are the main institutions of arctic research; geology, atmosphere, ecology and oceanography are the predominant disciplines of arctic research; oceans, islands and climate become the focus in this field.
