摘要 对Web of Science^(TM)核心合集数据库中地理信息系统(GIS)与健康相关的SCI论文进行计量学分析,统计高频主题词在同一文献中的出现频率并生成共现矩阵,使用SPSS对矩阵进行聚类分析,通过对各类文献内容分析进而获得该领域4个主要研究热点。 The paper makes a metric analysis of SCI papers on the Geographic Information System (GIS) and health in the database of Web of ScienceTM Core Collection, makes statistics of the occurrence frequency of high - frequency subject headings in the same litera- ture and generates a co - occurrence matrix.
