| 中文摘要: |
| 为了发现领域主题并研究其动态演进和发展规律,采用文献计量和专家咨询方法,以动物资源与育种领域为例,从引用关系、数据流和战略坐标三种视角对主题动态演进做了分析.首先,基于文献共被引识别领域主题,通过共被引时间线图对领域主题进行动态演进分析;其次,从数据流视角研究主题随着时间的融合、分化及延续等的动态演化;然后,通过战略图从向心度和密度方向对主题发展演化进行分析;最后,采用专家咨询法对分析结果进行评判和研读.结果表明:三个视角可以从多个方面、不同角度有效揭示主题演进情况,且文献计量结果与专家咨询基本一致. |

| In order to find the themes and to determine the themes dynamic evolutions in the specific area,the paperbased on the bibliometrics and expert consultation method to analyze the themes dynamic evolutionsof the Animal Resource Breeding from three different perspectives. Firstly, the paper based on the references co-cited analysis to find the themes, andto analyze the themes dynamic evolutions by the co-cited timeline map.Secondly, the paperanalyze the themes dynamic evolutions from the perspective of data stream. Thirdly, the paper analyze the themes dynamic evolutions through the radial and density direction of the strategic map, and finally, welet the experts of the field analysis and evaluate the research results. The results shows that:we can effectively reveal the themes evolutions from different perspectives,and the results from the bibliometrics and the expert consultation method almost unanimous. |
