基于Web of Science数据库的我国草地生态修复文献计量学研究

Bibliometrics research on grassland ecological restoration in China based on Web of Science database

草地退化是制约草原畜牧业可持续发展的关键因素,随着人们生态意识的提高,草地生态修复研究已经成为恢复生态学研究的重要领域。为了客观掌握我国草地生态修复的现状,本文以Web of Science数据库为数据源,以'restor OR rehabilitat OR regenerat OR establish'和'grassland OR steppe OR meadow'为关键词进行检索,对2005~2018年我国退化草地生态修复论文进行数据挖掘和定量分析,探究了近15年来我国退化草地生态修复的年发文量及期刊分布、影响因子分布、研究热点区域分布、研究使用方法以及论文被引情况。结果表明:近15年来,我国学者在该领域的年发文量成几何倍数的增长,论文影响因子约有94%在1-5之间,其中又有接近1/3的文章影响因子在3-4之间;刊登我国文章数最多的期刊是Ecological Engineering,占比接近13%;在296个样地信息中,我国草地生态恢复技术研究最多的省份是内蒙古,其次为陕西和西藏,依次占比25.3%、14.7%、12.8%;共有17种草地生态恢复技术被不同程度的应用,其中应用最多的草地生态恢复技术是围栏封育,其次为撂荒弃耕和人工补播,依次占比33.9%、25.3%、20.3%;所涉及的恢复目标共有36种,其中草地生产力、土壤碳库、植被盖度是草地生态恢复研究中关注最多的恢复目标。今后我国科研人员还应在退化草地土壤微生物学方面多下功夫,特别是根际土壤微生物结构和功能等方面的研究,这将有助于从微观层面解释退化草地植被恢复的生物学机理。

Grassland degradation is a key factor that restricts the sustainable development of grassland animal husbandry.With the improvement of people’s ecological awareness,grassland ecological restoration research has become an important area in restoration ecology.In order to grasp the current situation of grassland ecological restoration objectively in China,in this paper,the Web of Science database was used as the data source,and'restor OR rehabilitat OR regenerat OR establish'and'grassland OR steppe OR meadow'were used as the key words to retrieve data and quantitative analysis on the ecological restoration of degraded grassland in China from 2005 to 2018,researching the annual publications and journal distribution,the distribution of impact factors,the distribution of research hotspots,themethod used in the study and the cited cases of degraded grassland in China in the past 15 years.The results showed that in the past 15 years,The annual papers number of scholars in China in this field has grown geometrically;the impact factor of the papers about 94%is between 1-5,and nearly one-third of the articles with influence factors between 3-4;the journal with the largest number of articles in China is Ecological Engineering,accounting for nearly 13%;among the 296 plots,the province with the most research on grassland ecological restoration technology in China is Inner Mongolia,followed by Shaanxi and Tibe,respectively accounted for 25.3%,14.7%,12.8%;a total of 17 grassland ecological restoration techniques were applied to different extents and the most applied grassland ecological restoration technology is fenced enclosure,followed by abandoned abandonment and artificial reseeding,accounting for 33.9%,25.3%,and 20.3%,respectively;there are 36 restoration targets involved,among which grassland productivity,soil carbon pool and vegetation coverage are the most important recovery targets in grassland ecological restoration research.In the future,Chinese researchers can make more efforts in the soil microbiology of degraded grassland,especially the study of microbial structure and function of rhizosphere soil,which will help explain the biological mechanism of vegetation restoration in degraded grassland from the micro level.
