| 摘要: |
| 针对国际国内油料作物科技文献数据量过大、无法快速和有效交流等问题,利用共引分析、共词分析、信息可视化等方法和技术,借助Citespace信息可视化软件绘制油料作物研究领域的文献共引网络图谱、高被引文献的热点词汇图谱以及油料作物领域的前沿词汇图谱。直观地展示和分析了不同时期国际国内有关油料作物的高被引文献内容,分析了不同时期国际国内油料作物的研究热点。结果表明:国际国内有关油料作物高被引文献大多是关于实验方法和技术,近年来国内比较侧重于对油料作物产业及生物柴油方面的研究;国际国内有关油料作物早期的研究热点主要集中于油料作物的经济意义、生长环境、产量及品质等方面,近年来比较注重生物柴油的研究。 |

| Abstract: |
| This paper does visual analysis of international and domestic oil crops.Based on analytic techniques such as co-citation analysis、co-appearance analysis and information visualization,this paper maps the co-citation network、hot words of most cited papers and frontier on oil crop using the Citespace software.The paper conducts the co-citation and network analysis and keyword and term co-appearance analysis of international oil crops on the data downloaded from the Web of Science at Institute for Scientific Information (ISI),including SCI,SSCI,and A&HCI,using high-impact international journals as the data sources.The paper conducts the keyword co-appearance network analysis of domestic oil crop on the data downloaded from the China National Knowledge Infrastructure (CNKI),which is one of the toppest number published platforms.The results state clearly that high cited documents of international and domestic are mainly about the experimental method and technology while recently domestic researchers focus their attentions on oil crop industry and biodiesel,and the early research hot fields of international and domestic are both about economic significance of oil crops,growth environment,yield and quality while recently hot fields are about biodiesel. |
