基于下载量的综合类农业学术期刊半衰期研究

Study on Half-life of Comprehensive Agricultural Academic Periodicals Based on Downloads

为对文献老化速度提出新的研究思路,为给新形势下综合类农业学术期刊的科学评价提供参考,以《综合性农业科学学科期刊影响因子表(2016版)》确定的18种综合类农业学术期刊为例进行了分析研究。结果显示:在所研究的18种期刊中,44.44%的期刊下载量半衰期集中在2.5~3年,33.33%的期刊集中在3~4年;引用半衰期和被引半衰期的值均明显高于下载量半衰期,平均高出5~6年;下载量半衰期与基金论文比、被引半衰期呈正相关关系,且与被引半衰期的相关性显著。

In order to provide a reference for the scientific evaluation of comprehensive agricultural journals in the new situation, 18 kinds of comprehensive agricultural science and technology determined by the Comprehensive Agricultural Science Journal Influencing Factor Table （ 2016 ） were analyzed as an example. The results showed that： in the 18 journals in the journal, the downloads half-life of 44.44% concentrated in the 2.5-3 years, 33.33% concentrated in 3-4 years; cited half-life and cited half-life values were significantly higher than the average half-life of downloads with 5-6 years; half-life had positive correlation with fund paper ratio and cited half-life, while the correlation with the cited half- life was significant.
