植物 DNA 条形码研究领域文献计量学及可视化分析

In order to get the latest information and development researches filed of DNA barcoding of plants, and discuss its role in biodiversity conservation. Used bibliometrics, Histcite and citespaces to analyze literatures of DNA barcoding in plants based on Web of Sciences database to, and analyze Citation counts, research hot and research front visualization. The results showed the rate of contribution of literatures was the biggest of Chinese, American, Canadian authors. Chinese institutions published literatures counts than others countries, while literatures from American and Canadian institutions have more higher quality and influence. This research field has gotten peak at 2009 based on citation visualization analysis. The research front and hot focus on species identify and biodiversity application, find the suited candidates DNA barcoding sequences and refining the identical technology. Chinese authors play a leading role and have strength influence at DNA barcoding of plants. Chinese government encourages traditional Chinese medicine industry to promote the development of DNA barcoding technology at China. But the quality and influence of published literatures have a gap between China and developed countries, Chinese institutions should increase cooperation with the developed countries institutions and promote itself research ability. It is very important that DNA barcoding technology at species identify and biodiversity conversation. Tomorrows Outlook for Plant DNA Barcoding is building the global plant DNA barcode library and new DNA markers and new sequencing technologies.
