【摘要】：农业科学是重要的基础科学,其研究成果对于科学的发展具有十分重要的意义。农业科学文献作为农业科学研究成果的载体,在记录和发布已有的农业科学研究成果的同时,为农业科学的未来研究方向提供了参考和依据。随着农业科学研究的细化和深入,其研究领域不断拓宽,研究成果迅速积累,农业科学文献的数目大量增加,如何合理利用农业科学文献,为农业科学的发展提供助力,成为农业科学研究的一个新兴领域。引文分析是通过数学方法和逻辑方法研究文献的利用规律,进行科学评价、科学预测以及探究科学的发展规律的一种重要手段。因此,使用引文分析方法可以研究农业科学文献之间的相互引用关系,为农业科学文献的合理利用提供依据,从而推动农业科学的快速、持续发展。本研究在总结和发展已有研究的基础上,将"生命周期"的概念引入到引文分析理论中,归纳、总结了科学文献的被引生命周期的概念,利用基于被引生命周期的引文分析方法对农业科学文献进行了实证分析。本文的主要研究成果工作如下:介绍了引文分析的起源与发展,对国内外引文分析方法的研究现状进行了总结,比较、分析了已有的农业科学文献的引文分析方法,提出了基于被引生命周期的引文分析方法。将聚类分析方法和引文分析方法结合,根据文献被引生命周期的特点将其分为不同类别进行对比;通过绘制文献的被引生命周期曲线,实现对文献被引生命周期的直观分析;利用时间序列模型对文献的被引生命周期进行建模,借助数学工具对被引生命周期进行合理验证与科学解释。使用基于被引生命周期的引文分析方法对Web of Science中收录的1990年发表的农业科学文献进行了实证分析。根据文献被引生命周期的差异,利用K-MEANS聚类方法将文献划分为不同被引类型,分别绘制了文献被引生命周期曲线进行对比研究。然后,利用时间序列模型对Web of Science中收录的1990年发表的农业科学文献的被引生命周期进行建模。研究发现,农业科学文献的被引生命周期可划分为3个时期:引用增长期、引用稳定期和引用衰退期;根据农业科学文献在被引生命周期的差异,将其归结为4种不同被引类型:快速转折型、稳定增长型、正常引用型和持续增长型。同时,期刊被引生命周期形成原因较为复杂,多数期刊存在多种不同被引类型的文献,其被引生命周期由不同被引类型的文献的被引生命周期共同决定。
[Abstract]:Agricultural science is an important basic science, and its research results are of great significance to the development of science. As the carrier of agricultural scientific research achievements, agricultural scientific literature not only records and publishes the existing agricultural scientific research results, but also provides a reference and basis for the future research direction of agricultural science. With the refinement and deepening of agricultural scientific research, its research field has been widened, the research results have accumulated rapidly, the number of agricultural scientific documents has increased greatly, how to make rational use of agricultural scientific literature to provide assistance for the development of agricultural science, To become a new field of agricultural science research. Citation analysis is an important means to study the law of document utilization, to make scientific evaluation, to predict scientifically and to explore the law of scientific development through mathematical and logical methods. Therefore, the citation analysis method can be used to study the mutual citation relationship between agricultural scientific documents, provide the basis for the rational use of agricultural scientific documents, and promote the rapid and sustainable development of agricultural science. On the basis of summarizing and developing existing research, this study introduces the concept of "life cycle" into the theory of citation analysis, and sums up the concept of cited life cycle of scientific literature. The citation analysis method based on citation life cycle was used to analyze the agricultural science literature. The main research results of this paper are as follows: the origin and development of citation analysis are introduced, the current research situation of citation analysis methods at home and abroad is summarized, and the existing citation analysis methods of agricultural science literature are analyzed. A citation analysis method based on citation life cycle is proposed. Cluster analysis method and citation analysis method are combined to divide them into different categories according to the characteristics of the cited life cycle of the literature, and the visual analysis of the cited life cycle of the document is realized by drawing the cited life cycle curve of the document. The citation life cycle of literature is modeled by time series model, and the cited life cycle is verified and explained scientifically by means of mathematical tools. The citation analysis method based on citation life cycle was used to analyze the agricultural science published in 1990 in Web of Science. According to the difference of citation life cycle of literature, the paper is divided into different citation types by K-MEANS clustering method, and the citation life cycle curve is drawn separately for comparative study. Then, the citation life cycle of the agricultural science published in 1990 in Web of Science was modeled by time series model. The study found that the cited life cycle of agricultural scientific literature can be divided into three periods: citation growth period, citation stable period and citation decline period; according to the differences of agricultural scientific literature in the cited life cycle, It can be divided into four different citation types: fast turning type, stable growth type, normal citation type and persistent growth type. At the same time, the cause of citation life cycle is more complex, most journals have many different citation types of literature, their cited life cycle is determined by the cited life cycle of different citation types of literature.
