依据《中国科技期刊引证报告》(CJCR)的数据,统计分析了2007～2011年化学类期刊的影响因子、总被引频次、载文量、他引率和基金论文比等主要文献计量指标,通过各项指标的均值和年均增长率探讨期刊的集中发展趋势;讨论了5年影响因子和5年总被引频次平均值排名前15位的化学类期刊的情况,对比了10种化学期刊的载文量与影响因子和总被引频次的变化趋势。结果表明,化学类期刊的学术影响力逐年稳步增长,其中高学术影响力的期刊所占比例较大,位于中国科技期刊的前列。分析化学专业期刊的综合学术影响力处于化学类期刊的领先地位。然而,CJCR化学类期刊主要计量指标的平均发展速度低于CJCR全部期刊相应指标的平均发展速度。化学类期刊应进一步探索创新发展之路以提高学术质量,创造精品期刊,参与国际竞争。
According to the data of China Science and Technology Journals Citation Index (CJCR), the main literature indexes of chemical journals from 2007 to 2011, such as the total number of citations, the number of papers cited, the lead rate and fund theses, were statistically analyzed. The average value of each indicator and the average annual growth rate to explore the focus of the development trend of the journal; discussed the five-year impact factor and the five-year total citation average of the top 15 chemical journals, compared 10 chemical journals The number of papers and the impact factor and the trend of the total cited frequency. The results show that the academic influence of chemical journals has been steadily increasing year by year, among which journals with high academic influence have a large proportion and are at the forefront of Chinese sci-tech periodicals. The comprehensive academic influence of analytical chemistry journals is at the forefront of chemical journals. However, the average rate of development of major quantitative indicators in CJCR’s chemical journals is lower than the average rate of growth of corresponding indicators in all Journals of CJCR. Chemical journals should further explore the path of innovation and development to improve academic quality, create quality journals and participate in international competition.
