本文依据2004～2010年CJCR数据,分别讨论中国科技期刊来源指标和引证指标的变化趋势。期刊登载的论文总量、参考文献总量、基金论文总量、最大他引量、即年指标、总被引频次等各项评价指标均呈现增长趋势,年总被引频次少于50的期刊越来越少;年总被引频次大于1000的期刊增长很快,影响因子小于0.2的期刊数逐年减少,影响因子在[0.3,1]间的期刊逐年增多。结果表明,期刊的影响力是逐年提高的,期刊对科学信息量的吸收与扩散能力、科学工作者对科学继承和尊重的素养程度提高,学术研究传承速度增加,学科自身的引用和学科间的交叉引用更加频繁,也反映了目前科学研究的广域化、开放化和合作化程度加强。
Based on the CJCR data from 2004 to 2010, this paper discusses the changing trend of the source index and quoted index of Chinese sci-tech periodicals respectively. The total number of papers published in journals, the total number of references, the total amount of fund papers, the maximum of his quotations, the annual index, the total number of citing times and other indicators of the evaluation showed an upward trend in the total annual citation less than 50 journals The number of journals whose total annual citation frequency is more than 1000 increases rapidly, the number of journals whose impact factor is less than 0.2 declines year by year, and the number of journals with influence factor of [0.3,1] increases year by year. The results show that the influence of journals is increasing year by year, the ability of journals to absorb and disperse the amount of scientific information, the improvement of scientific workers’ ability to inherit and respect sciences, the increase of academic research heritage, the reference of subject itself and the interdisciplinary Cross-references are more frequent, and also reflect the widening of the current scientific research, opening up and cooperation to enhance the degree.
