基于Web of science数据库的ACC脱氨酶研究文献计量分析

摘要

随着土壤环境日益恶化,ACC脱氨酶(l-Aminocyclop ropane-1-carboxylate deaminase)提高植物抗逆性及生态修复功能越来越受到关注.基于文献数据库,客观分析当前国际ACC脱氨酶研究的发展动态,旨在推动我国ACC脱氨酶相关研究及其在土壤污染修复中的应用.基于Web of science数据库,采用文献计量学方法,对全球发表于1991-2016年的ACC脱氨酶研究论文的国家、机构、作者、研究领域、期刊及关注热点进行统计分析.ACC脱氨酶全球论文数量在近几年呈现出持续增长态势.其中印度、加拿大和巴基斯坦在ACC脱氨酶研究领域处于国际领先地位,加拿大的发文量和发文影响力均位于首位,研究力量集中,研究人员实力较强.中国在ACC脱氨酶方面的研究起步较晚,发文数量虽然排名全球第四,但其影响力较低.全球范围内,ACC脱氨酶的研究内容主要集中在农业生产及环境修复两个方面.中国从微生物生态学、植物与微生物互作及植物修复等多个方向开展研究,也是今后值得重点关注和跟踪研究的方向.加拿大的研究力量处于国际领先水平.我国在该领域的研究起步晚,但近五年发展速度较快,关注热点体现出一定的特色和前瞻性,今后要注重高水平论文的发表,同时加强与高水平研究机构之间的合作,带动该领域研究力量的整体提升.%As the soil environment is increasingly deteriorating,the potential use of ACC deaminase in improving plant tolerance and bioremediation has received significant attention in recent years.Our aim is to objectively analyze the current development of ACC deaminase studies worldwide,thus to promote the development of related research work and their utilization in bioremediation of contaminated soils in China.Based on Web of science database,the countries,institutions,authors,research fields,journals and key words of ACC deaminase literatures published during 1991-2016 are quantitatively and qualitatively analyzed.The ACC deaminase publications have witnessed a continued increase in recent years all over the world.India,Canada and Pakistan are in a leading position in the ACC deaminase research field.Both of the number and influence of the ACC deaminase publications of Canada rank the first.The ACC deaminase study in Canada has focused and strong research strength.The ACC deaminase research in China initialized late.Although the number of published paper of China ranks the fourth place worldwide,the influence is low.The worldwide research area of ACC deaminase mainly focused on agricultural production and environmental remediation.The research area in China mainly concentrated on microbial ecology,plant-microbe interaction and phytoremediation,which are worth focusing and tracking in the future.The research strength of ACC deaminase in Canada ranks the first all over the world.This research field in China started late,but has been developing rapidly during the recent five years.The hot topics of attention are also unique and forward-looking.Nevertheless,more efforts are still needed to publish high level papers,at the same time strengthening the cooperation with high level research institutes,thus to drive the overall improvement of the research strength ofACC deaminase in China.
