福寿螺属主要入侵种(Pomacea canaliculata和Pomacea maculate)研究趋势可视化

Visualization of Research Trends of Main Invasive Species(Pomacea canaliculata and Pomacea maculate)of Pomacea genus

为了解和对比近些年来国内外福寿螺领域研究趋势和热点内容,本文以中国知网(CNKI)和Web of Science(WOS)核心文集TM的科学引文索引扩展版SCI-E数据库为数据来源,运用CiteSpace和VOSviewer软件对2009—2021年福寿螺属中入侵能力最强、入侵范围最广的两种物种(Pomacea canaliculata和Pomacea maculate)研究领域的813篇相关文献(中文文献398篇,英文文献415篇)进行年度发文量、作者和国家合作网络、关键词共现、聚类和突现以及文献共被引分析.结果显示:自2009年来,国际上福寿螺领域研究热度持续,发文总体呈波浪式增长;国内研究热度有所减缓,发文总体呈下降趋势.在该领域内,国内发文地区主要集中在我国长江中下游以南及沿海地区;国际上,中国、阿根廷、美国、巴西是主要的发文国家.我国发文量位居第一,与阿根廷、美国构成该领域研究的主要国家力量.国家间合作密切,合作网络覆盖亚洲、南美、北美、西欧和澳大利亚各大区域.国内外近年来在该领域的研究热点有所不同,广州管圆线虫病、福寿螺的抗逆性和防治是我国近些年甚至未来很长一段时间研究关注的重点;在世界范围内,近年来的研究热点则是个体识别与鉴定、系统发育分析、物种地理起源和进化方面.此外,蛋白质组、卵、渐渗杂交福寿螺的危害和可利用化是目前国际在该领域的研究前沿.

To understand and compare the research trends and hot topics in the field of Pomacea genus worldwide in recent years, with the China CNKI database and the SCI-E database(Extended Edition of the Scientific Citation Index)of the core corpus of Web of Science(WOS)databaseTMas the data source, CiteSpace and VOSviewer softwares were utilized to analyze the annual number of articles, author and national cooperation network, keyword co-occurrence, clustering and bursting, and literatures co-citation of 415 related articles(398 in Chinese and 415 in English)in the research field of two species(Pomacea canaliculata and Pomacea maculate)with the strongest invasion ability and the widest invasion scope in the genus Pomacea from 2009 to 2021 were conducted. The results show that, since 2009,the international research in this field has been hot, and the number of published articles has generally increased in waves, while the domestic research has slowed down, and the number of published articles has generally declined. In this field, domestic publishing areas are mainly concentrated in the south of the middle and lower reaches of the Yangtze River and coastal areas, Internationally, China, Argentina, the United States and Brazil are the main countries that publish articles. China has the largest number of publications and constitutes the main national force in this field with Argentina and the United States. Close cooperation among countries, the cooperation network covers Asia, South America, North America, Western Europe and Australia. In recent years, the research hotspots in this field are different at home and abroad, Angiostrongylus cantonensis and Ampullaria gigas’ s stress resistance and control are the focus of research in China at present and even in the future for a long time. In the world, the research hotspots in recent years are individual identification, phylogenetic analysis, geographical origin and evolution of species. In addition, damage and using, protein formation, egg and introgression hybridization are the international research frontiers in this field.
