摘要
有害藻类水华是严重影响社会经济可持续发展的生态灾害,频发于世界范围内的淡水和海洋水体.通过检索水华相关的中英文期刊文献,利用CiteSpace等软件进行科学知识图谱分析.结果显示:(1)目前发表的水华研究相关的中英文期刊论文达4.4万余篇,根据年发文量大致可将全球水华研究划分为3个阶段:Ⅰ(1942~1990年,<200篇/年)、Ⅱ(1991~2014年,<2000篇/年)和Ⅲ(2015年至今,>2000篇/年).(2)水华研究的国际合作较为密切,英文文献以美国发文量最多、中国第二.中文的水华研究论文以中国科学院为中心形成协作网络,水华研究的主要内容大致与国际上吻合.(3)中国的水华研究在全球水华研究中占据重要地位.在新兴前沿领域,中文期刊所发表的研究内容稍滞后于英文期刊.(4)关键词共现展示了水华研究的热点内容;突现词揭示了3个研究阶段新兴前沿领域的变化;关键词聚类则反映了全球水华研究的主要内容,进而可以推测未来的发展趋势.多尺度结合可能成为今后水华研究的一种趋势.水华监测预警建模、遥感技术、大数据和人工智能分析等已成为重要的研究方法.水华形成和消亡机制依然是核心科学问题.水华全生命周期过程生态环境效应的定量化研究和人类活动与水华发生的互馈机制可能是今后的重要研究内容.
Worldwide,proliferating harmful algal blooms(HAB)have been an ecological catastrophe with negative impacts on ecosystem health,safe water use and sustainable socioeconomic growth.HABs impact nutrient-overenriched eutrophic freshwater and marine water bodies.Here,we searched the HAB literature database for English and Chinese journal articles.Then,we utilized CiteSpace and other software to analyze its scientific knowledge graphs.The results showed:(1)Growing attention and concern about the proliferation and intensification of HABs since the 1940s.Currently,more than 44000 publications(including 172 highly cited papers)have been published in English and Chinese journals.(2)Based on annual publication volume,global HAB research can be roughly divided into three periods:Ⅰ(1942−1990,<200 articles per year),Ⅱ(1991−2014,200 to 2000 articles per year),Ⅲ(from 2015 to the present,>2000 articles per year).(3)Prof.Paerl(153 papers)and Prof.Songhui Lü(77 papers)were the scholars with the most publications in English and Chinese articles,respectively.The most prevalent journals for HAB research publications are Harmful Algae and Journal of Lake Sciences in English and Chinese journals,respectively.The findings published in Limnology and Oceanography are crucial to an in-depth understanding of HAB dynamics.(4)The largest source of English literature is the United States and the second is China.There is a growing amount of international interaction and collaboration in HAB research.In Chinese publications,the Chinese Academy of Sciences is at the core of collaborative networks conducting HAB research in China,and its major standing on algal bloom research is on par with the international levels.(5)In terms of worldwide HAB research,Chinese HAB research has a significant place.However,Chinese journal articles’research output appears to lag behind that of English journal articles in terms of new directions and perspectives.(6)The co-occurrence of the keywords reveals the popular topics in HAB research.Emergent words
