林业学科SCI网络版期刊的指标分析及中国论文分布

Indices analiysis of forestry journals in SCI-E web and the distribution of papers from China

利用美国科学情报研究所(ISI)发布的SCI网络版期刊源及2002年度期刊引文报告(JCR2002)数据,对所收录的林业学科期刊进行了汇总介绍。着重对主要的几项期刊指标在林业学科期刊中的分布情况进行比较分析。从中得知林业学科期刊的各项指标明显低于JCR2002期刊总体指标。如林业类期刊与JCR2002相比刊均论文数低82 0%,平均被引用频次低61 9%,影响因子的平均值约少一半。对近3aSCI收录我国在林业类期刊上发表论文的情况进行了统计分析。SCI在林业类期刊中收录的我国科研人员主持或参与的102篇论文分别发表在10个国家的21种期刊上,被引次数在10次以下的论文有101篇,占99%。论文在高校、中国科学院、林业科学研究院和其他四大类中的分布分别占54 9%,28 4%,12 7%和3 9%,高校优势明显。提出利用SCI对我国林业学科进行科技评价的思考及建议。

Using the data in the 2002 edition of the ISI Journal Citation Reports,forestry journals indexed by SCI were summarized. The main indices of journals in forestry subject were compared with the mean value of indices of journals included in JCR. The results showed that the indices of journals in forestry subject were significantly lower than the average ones of JCR 2002. For example, the number of papers in each forestry journal and cited frequency was 82.0% and 61.9% fewer than those in JCR 2002 respectively. The mean value of influential factors of the former was about 50% fewer than the latter. A statistic analysis of the Chinese papers in forestry journals included in SCI in recent three years was conducted. The 102 papers written or co-written by Chinese researchers included in SCI forestry journals were published in 21 journals from 10 countries. 101 papers were cited less than 10 times, accounting for 99%. Paper writers from universities and colleges, China Academy of Sciences,academy of forestry and other institutions account for 54.9%, 28.4%, 12.7% and 3.9% respectively. Suggestions on the scientific evaluation of forestry in China on the basis of SCI are put forward.
