- 摘要:
- 以2003~2012年我国10 a间的园艺学领域的SCI论文为对象，以信息分析领域中影响力较大的信息可视化软件CiteSpace为工具，采用科学知识图谱法，对我国园艺学领域的研究力量、研究热点和研究前沿进行可视化分析。结果表明：近10 a来我国园艺学的研究主要集中在中国科学院、华中农业大学、中国农业科学院、中国农业大学、南京农业大学、浙江大学；中国农业科学院与其他机构的合作最多；根据主题词出现的频次进行分析可知，分子标记、遗传学研究、数量性状位点、育种、抗氧化酶、表型变化研究、基因精细定位7个方面代表了园艺学领域的研究热点；以中间中心性为指标进行园艺学领域关键点的测度显示,图位基因克隆、简单重复序列、遗传距离、QTL图谱定位、氨基酸类为园艺学领域的关键节点，是园艺学领域一个研究方向到另一个研究方向的转折点；通过探测突变专业术语（Burst terms），并进行共聚类分析可知，园艺学的研究前沿主要为数量性状位点、抗氧化酶（活性）以及植物再生等。
- Abstract:
- Taking ten years’ SCI papers of horticultural science published by researchers in China from 2003~2012 as objects，with influential information visualization software CiteSpace as tool，the research strength，research topics and fronts in horticulture were visual analyzed using scientific knowledge mapping method.The results showed that the horticultural research in nearly 10 years were mainly in Chinese Academy of Sciences，Huazhong Agricultural University，Chinese Academy of Agricultural Sciences，China Agricultural University，Nanjing Agricultural University and Zhejiang University.Among them，Chinese Academy of Agricultural Sciences had the most cooperation with other organizations.The research topics were molecular markers，genetic study，quantitative trait loci，breeding，antioxidant enzymes，phenotypic change，gene mapping according to the analysis of keywords frequency.The measure of horticultural science key points showed that figure-bit clone，simple sequence repeats，genetic distance，QTL mapping，amino acids were the key nodes，and it was a turning point from a research direction to another.By detecting mutations jargon and copolymerization analysis，the research fronts were quantitative trait loci，antioxidant enzyme and plant regeneration.
