基于文献计量的中国水产养殖技术研究态势分析

为了及时掌握国内水产养殖技术领域的科研发展动态，为科研人员、科研管理部门以及科技期刊编辑提供参考。本研究运用文献计量学方法，选取中国知识链接数据库2012—2016 年的分类号为S96 的论文及其在2017 年的被引数据，从学科发文量、高被引、主题关联、学科高影响力期刊、高被引作者及机构等几个方面进行分析。结果显示：2012—2016 年水产养殖技术领域共有14168 位来自6358 所机构的论文第一作者在996 种期刊上发表了20789 篇学术论文，有3427 篇在2017 年被引用，整体被引率为21.3%，总被引频次为5459 次，篇均被引0.26 次。2017 年被引频次位居前10 位的论文平均被引频次为10.1 次，是全部38 篇高被引论文篇均被引频次的1.4 倍。氨基酸、生长性能、脂肪酸等关键词的使用频率较高，是2017 年学科的研究热点；以氨基酸、脂肪酸、肌肉、质构特性、营养价值等关键词为主要节点的多个概念相互关联，构成了学科内最为突出的研究主题簇。h 指数位居前3 位的期刊分别是《水产学报》、《动物营养学报》和《水生生物学报》。高被引作者的5 年学科发文数量1~11 篇不等，同时，作者学科发文的期刊分布在1~8 种间。水产养殖技术领域的高被引作者的论文合作现象比较普遍。研究结果显示，随着科研基础不断夯实，水产养殖技术研究能力不断提升，以中国水产科学研究院、中国海洋大学、上海海洋大学、广东海洋大学为主体，以《水产学报》、《水生生物学报》及《中国水产科学》为载体的水产养殖技术学科发展将会得到稳步发展。

Bibliometrics-based Analysis of Highly-cited Papers of Aquaculture Technology in China

In this study, the bibliometrics method was used to analyze published papers in Chinese knowledge link database with the classification number S96 from 2012 to 2016, and their citation data in 2017 in the aspects of discipline publication, citation, topic relevance, discipline high-impact journals, highly-cited authors and institutions, aiming for sticking with the development trends of aquaculture technology in China, and providing references for researchers, scientific research management departments and editors of scientific journals. Results showed that: from 2012 to 2016, a total of 14168 papers from 6358 institutions in the aquaculture technology field published 20789 academic papers in 996 journals, and 3427 papers were cited in 2017, with an overall citation rate of 21.3%. The total citation frequency was 5459, the citation frequency per paper was 0.26. The average citation frequency of the top 10 papers cited in 2017 was 10.1, which was 1.4 times that of all 38 highly-cited papers. Keywordssuch as “amino acid”, “growth performance” and “fatty acid” have higher appearing frequency of documents, which demonstrated a research hotspot in 2017. Multiple concepts with Keywordssuch as “amino acid”, “fatty acid”, “muscle”, “textural property”, and “nutrition value” are related to each other, which constituted the most prominent research cluster in the discipline. The top three journals of the h index are Journal of Fisheries of China, Chinese Journal of Animal Nutrition, and Acta Hydrobiologica Sinica. The number of articles published by the highly-cited authors in the five-year discipline ranges from one to eleven. Besides, the distribution of journals varies from one to eight. Collaborative papers by highly-cited authors in the field of aquaculture technology are more common. In this study, we could find that with the continuous improvement of scientific research foundation, the research capacity of aquaculture technology is continuously improved. The development of aquaculture technology disciplines will be steadily based on the mainstay of the Chinese Academy of Fishery Sciences, China Ocean University, Shanghai Ocean University and Guangdong Ocean University, with the surport of scientific jounrals such as Journal of Fisheries of China, Acta Hydrobiologica Sinica and Journal of Fisheries Sciences of China.
