基于文献计量学的原理和方法，以“桃金娘”为检索词，对维普期刊1989至2015年间国内公开发表的有关桃金娘的研究文章进行检索。针对文献的研究年代分布、主要集中分布刊物，发表2篇以上文献作者、关键词出现的次数等方面进行了详细分析，揭示出该植物的研究概况。发现这些文章多集中于讨论桃金娘的化学成分，还没有深入到基因型及遗传多样性。文章认为这正是桃金娘的一个研究方向。%Based on the principle and method of literature metrology, VIP database with the keyword of "Rhodomyrtus Tomentosa" was searched, during the years from 1989 to 2015, the growth, literature distribution, literature mainly concentrated distribution of publications, the author published 2 paper or more. The number of occurrences of keywords has been carried on the detailed analysis, reveals the general research situation of the plant. It was found that most of the research works focus on discussion on chemical constituents, it was unclear about the genotype and genetic diversity about Rhodomyrtus Tomentosa. This paper argues that it is one of the key problems to be solved urgently in the field.
