论文部分内容阅读
以中国期刊网全文数据库(CNKI)镜像版为统计来源,以数据库所列农业核心期刊1997、2002和2007年发表学术论文为研究对象,利用等距离随机抽样方法采样,分析无引文论文比例及引用不当情况、篇均引文数、引文在文中分布、引文年限、引文语种和引文类型等。结果显示:①1997年无引文论文比例占51.34%,2002年为28.66%,2007年为6.43%;②篇均引文数逐渐提高,1997年为8.2,2002年为9.8,2007年为14.4;③引文在文中分布比例各年份一致,以引言中引用比例最高,年均为52.35%,其次为结论与讨论(38.49%)、材料与方法(22.00%)和结果与分析(17.74%)。这一结果体现了科技工作的继承性和引文的索引作用;④引文类型以期刊为主,其次为图书,其他文献类型占的比例很小;⑤中文和英文引文占绝大部分;⑥≤5 a,5～10 a,>10 a的引文比例之间差异不明显。从结果可见,农业期刊对引文的重视程度逐渐提高,但编辑和作者对引文作用仍认识不够,引用不认真不仔细,需引起重视。
Taking CNKI mirror version as the statistical source and the agricultural core journals listed in the database as the research subjects in 1997, 2002 and 2007, sampling was conducted by using the equidistant random sampling method to analyze the proportion and citation of the non-cited papers Citation number, citation distribution in the text, citation period, citation language and citation type. The results showed that: ①The proportion of non-cited papers accounted for 51.34% in 1997, 28.66% in 2002 and 6.43% in 2007; ②The number of citation per article gradually increased from 8.2 in 1997 to 9.8 in 2002 and 14.4 in 2007; ③Citation The proportions in the text are the same for all years, with the highest citation rate in the introduction, with an annual average of 52.35%, followed by conclusions and discussion (38.49%), materials and methods (22.00%) and results and analysis (17.74%). This result reflects the inheritance of science and technology and the indexing effect of citations; ④The types of citations are mainly periodicals, followed by books, and the proportion of other types of documents is very small; ⑤ Chinese and English citations make up the majority; ⑥≤5 There was no significant difference between citation rates of a, 5 ~ 10 a and> 10 a. It can be seen from the results that the priority of agricultural journals on citations is gradually increasing. However, editors and authors are still not sufficiently aware of the role of citations. Their citation is not careful and should be taken seriously.
