摘　　要：目的分析中文眼科学专业期刊所载论文的引文和论文被他刊引用情况,了解眼科学领域文献的利用与需求特征。方法以2001年公开发表的13种中文眼科学专业期刊为研究对象,采用引文计量学方法对所载论文的引文数量、类型、语种、自引率及他引率等进行统计分析,同时对其中5种眼科学核心期刊从引文年限分布、普赖斯指数及引文半衰期、论文被引情况等方面进行分析。结果2001年13种眼科学专业期刊引文总量为16429条,篇均引文量5.13条,平均引文率77.42%,自引率23.49%、他引率76.51%;引文语种以英文为主(59.17%),主要的引文类型为期刊(89.25%)。2001年5种眼科学核心期刊论文中,中、外文文献分别在出版后第3、4年引用频次最高,引文的总普赖斯指数为35.22%,中、外文引文文献半衰期分别为5.12年及7.52年。结论中文眼科学专业期刊引文主要来自英文期刊,中文文献引用半衰期较短,眼科学核心期刊被引率高。Objective To investigate the utilization and the requirement of literatures by the researchers through analyzing and valuing citation of the ophthalmological journals in Chinese. Methods There were 13 journals, of which five were core journals, to publish the results of primary study in ophthalmology in 2001. The citation amount and type, language category, self-citing rate of 13 journals were calculated. Meanwhile, the time distribution of citation, the Price index, the half-citing life and the cited situation of 5 core ophthalmological journals were investigated. Results In 2001, total amount of citations of 13 journals were 16 429. The mean citations per article were 5. 13, and the mean citation rate 77.42%, self-citing rate 23.49%, other-citing rate 76. 51%. The major language of citation was English （59. 17% ）, and the major citation was from journals （89. 25% ）. In 5 core ophthalmological journals, the time distribution of foreign language and Chinese references ranked at highest was the fourth and third year, respectively, after they were published. The total Price index of citations was 35.22% ,the half-citing life of the Chinese and English references was 5. 12 and 7.52 years, respectively. Conclusions The main citations of 13 ophthalmological journals came from the English journals. There was a short half-citing life for Chinese literatures.Cited-papers in Chinese were mainly from five core ophthalmological journals. （Chin J Ophthalmol , 2006, 42： 443-447）
