摘要：

【目的】 分析《湖泊科学》近10年的自引行为变化规律,剖析产生原因,思考期刊非正常自引现象,引导期刊自引的客观认识,更好地办好学术期刊。【方法】 根据《中国科技期刊引证报告(核心版)》的数据以及《湖泊科学》2006—2015年载文的参考文献,得到《湖泊科学》近10年的自引率(R_SC),总被引频次(F_TC),总自引频次(F_SC),对影响因子(IF)有贡献的总被引频次(F_TCIF)、自引频次(F_SCIF),自引率(R_SCIF),载文数量,平均引文数量以及IF等评价指标,分析各指标的变化趋势以及相互之间的关系。【结果】 在无人为操控的前提下,《湖泊科学》近10年R_SC变化较小,F_TC、F_SC、F_SCIF以及载文数量均有升高趋势,R_SCIF略高于R_SC,但是自引对IF无显著影响。【结论】 R_SC与学科大小和研究范围有关。增加科研投入、提升期刊内容质量、应用数字化手段以及加大推广力度等因素导致了F_TC、F_SC和F_SCIF等指标升高。期刊出现R_SC过高或突然大幅度升高、F_SCIF与IF有很强的相关性、R_SCIF大大高于R_SC等现象时,很可能是人为操控所致。中国科技期刊编辑只有自律自强,才能够使得中国科技期刊的学术质量真正获得国内科技工作者的认同并且在国际舞台上占有一席之地。

Abstract:

[Purposes] This study aims to analyze change laws of self-citation and corresponding reasons for Journal of Lake Sciences published in recent 10 years and explore abnormal phenomenon of journal self-citation to guide people to objectively understand the self-citation of academic journal and lay a solid foundation for the journal developments in further steps. [Methods] Based on the data from Science and Technology Journal Citation Report and statistical results from references of Journal of Lake Sciences published from 2006 to 2015, the variation of the journal evaluation indexes, such as self-cited rate (R_SC), total cited frequency(F_TC), total self-cited frequency (F_SC), self-cited frequency (F_SCIF), total cited frequency (F_TCIF), and total self-cited rate (R_SCIF) which are related to impact factor (IF), paper quantity, and average citation quantity, and their correlation, were analyzed. [Findings] Under the natural condition, the R_SC of Journal of Lake Sciences in recent 10 years does not change so much. The F_TC, F_SC, F_SCIF and paper quantity increase. The R_SCIF is slightly higher than R_SC, but it has no significant impact on IF. [Conclusions] The R_SC is related to the subject scope. The increasement of research and development investment for scientific research, improvement of journal article quality, application of digital tools, and enhancement of journal visibility lead to the increasement of F_TC, F_SC and F_SCIF. Possible indications show that the journal may be artificially manipulated, especially by journal editors when the R_SC is too high or increases drastically, F_SCIF is closely correlated with IF, and R_SCIF is much higher than R_SC. Chinese editors of academic journals should pay more attention on content quality instead of evaluation indexes in order to obtain domestic recognition from scientists and international visibility for their journals in the world.
