| 为全面了解植物DNA条形码研究领域的发展和最新动态,探讨中国DNA条形码发展的状态和前景,该文利用Web of Science 数据库对该研究领域进行文献计量学统计,并对引用频次、研究热点和研究前沿进行了可视化分析。结果表明:(1)中国、美国、加拿大学者在该领域文献贡献率最大,中国研究机构发文量领先,但美国、加拿大科研机构论文质量较高,影响力较大。(2)2009年是该领域研究的高峰期,该研究领域的前沿和研究热点主要集中在物种的识别和生物多样性应用、DNA条形码候选序列筛选和鉴定技术的规范化。(3)中国学者在植物DNA条形码领域研究具有领军作用和很高的影响力,国家提倡中药产业的发展也推动了我国DNA条形码蓬勃发展,但论文的质量和影响力与美国、英国、加拿大等发达国家研究还有一定差距,应加大与发达国家科研机构合作,提高研究能力,DNA条形码技术在植物的鉴定、分类和生物多样性的保护起到非常重要的作用。这表明建立一个更全面、通用的全球植物DNA条码库以及开发新的标记并采用新的测序技术是植物DNA条形码研究的未来前景。 |

| Abstract: |
| In order to obtain the latest information and development research filed of DNA barcoding of plants, and to discuss its role in biodiversity conservation, we used bibliometrics, Histcite and Citespaces to analyze literatures of DNA barcoding in plants based on Web of Sciences database, and analyzed citation counts, research hot and research front visualization. The results were as follows:(1)The rate of contribution of literatures from Chinese, American, Canadian authors was the highest. Chinese institutions published literatures counted more than others countries, while literatures from American and Canadian institutions had much higher quality and influence.(2)This research field reached the peak at 2009, and the research front and hot focused on species identify and biodiversity application, find the suited candidates DNA barcoding sequences and refining the identical technology.(3)Chinese authors played a leading role and had strength influence at DNA barcoding of plants. Chinese government encouraged traditional Chinese medicine industry to promote the development of DNA barcoding technology at China. But the quality and influence of published literatures had a gap between China and deve-loped countries, and Chinese institutions should increase cooperation with the deve-loped countries institutions to promote itself research ability. It is very important that DNA barcoding technology at species identify and biodiversity conversation. Tomorrow's outlook for plant DNA barcoding is to build a global plant DNA barcode library, new DNA markers and new sequencing technologies. |
