中华眼科杂志2001至2004年引文分析

目的研究中华眼科杂志文献引用规律及我国眼科学研究领域科研人员的文献利用与需求特征。方法采用引文计量分析法,统计中华眼科杂志2001至2004年间刊载的926篇论文所引用的参考文献(引文)。结果926篇论文中,有引文的论文共850篇,引文率为91．79％,篇均引文8．05条;引文中期刊912种(91．97％),图书266种(7．85％);普赖斯指数35．50％;期刊自引626条,自引率8．40％。被引用频次居前17位的中、外文期刊的引文量占总引用期刊引文量的54．03％。结论中华眼科杂志涉猎文献范围广,引文类型以期刊为主,语种以英文文献为多,引文的外文语种结构较为单一,研究引用文献比较滞后,文献半衰期较长,专业人员利用近5年内新文献的能力有待于进一步提高。

OBJECTIVE: To study the aspects of citation of the Chinese Journal of Ophthalmology and the requirement and utilization of literatures by the scientists working in the field of ophthalmology. METHODS: The citation analysis was used to analyze the references cited in the 926 articles published in the Chinese Journal of Ophthalmology from 2001 to 2004. RESULTS: The citation rate was 91.79% and there were 8.05 citations per article. Citations from journals and books accounted for 91.97% and 7.85% of all citations, respectively. The Price Index was 35.50% and the self-citation rate was 8.40%. The citations from the high-ranked 17 journals accounted for 54.03% of all citations. CONCLUSIONS: The articles cited by papers published in the Chinese Journal of Ophthalmology cover a wide variety of journals. Most citations came from the English journals. The half-citing life is relatively longer and the Price Index is relatively low. It indicates that the authors' ability for using the recently published articles should be improved.
