松材线虫病是世界松林最严重的病害,引起各国学者广泛研究。以ISI Web of Science平台的Web of Science^(TM)作为数据源,采用文献计量学的方法,对2002—2016年间发表松材线虫病文献的国家、机构、作者、载文期刊、基金资助机构、学科类...松材线虫病是世界松林最严重的病害,引起各国学者广泛研究。以ISI Web of Science平台的Web of Science^(TM)作为数据源,采用文献计量学的方法,对2002—2016年间发表松材线虫病文献的国家、机构、作者、载文期刊、基金资助机构、学科类别和关键词进行分析。结果表明,全球56个发文国家中,以松材线虫病危害程度最高的亚洲3个国家:日本、中国和韩国,发文数量最多,影响力最高;全球排名前10的研究机构和作者也主要分布于这3个国家中;研究方向则更倾向于动物学、林学和昆虫学方向;载文期刊中,刊载中国学者论文的期刊质量与国际上排名前10的期刊质量还有一定差距;关键词共现网络表明近15年的研究热点为:松墨天牛、生物防治、黑松、鉴定、致病性、传播和拟松材线虫。展开更多
