中国荒漠草原的研究态势与热点分析——基于文献计量研究

Abstract

荒漠草原是我国草原的重要组成部分，对保障粮食安全、生态安全具有极其重要的作用。为了解中国该领域研究态势，运用文献计量方法，基于36年间国内外发表的3651篇论文，分析了发文量、发文来源、被引频次、主要作者、研究机构和研究热点等。结果表明：（1）2000年后关于荒漠草原的论文数量增幅较大，年均发表超160篇，但篇均被引频次、高质量学术期刊发文量和创新性研究成果较少，整体发文质量还有待进一步提高；（2）具有创新性的评价方法和理论研究一直备受关注，而利用荟萃分析方法对某一研究领域进展的分析得到了学者们的认可；（3）韩国栋、宋乃平、卫智军、周广胜等是荒漠草原研究的主要贡献者，内蒙古农业大学和宁夏大学等单位在发文机构合作间的节点上发挥了重要作用，并形成了荒漠草原研究的网络核心，但中文论文研究机构间的合作较英文论文离散程度高，特别是与国外机构的合作相对较少；（4）研究的热点主要集中在人类活动和气候变化对荒漠草原植被-土壤系统的影响、荒漠草原植被生产力及其影响因素、利用孢粉研究植被和环境变迁等方面。未来荒漠草原的研究应加强国内外机构和人员间的合作创新，从多尺度、多维度应用多学科知识、多技术手段，加强人类活动和气候条件相互作用对荒漠草原植物群落结构进化过程、地上与地下生态过程耦联关系、不同营养级之间内在机理的分析和探讨。通过深度挖掘荒漠草原基础数据，以促进高影响力、高质量成果的产出，实现科研成果量变与质变并举、基础研究与实际应用并重，期望能给荒漠草原的相关研究提供借鉴和启发新方向，为中国草地建设和决策提供科学依据。;Desert steppe is an important part of grassland in China, which plays an extremely important role in ensuring food security and ecological security. In order to understand the research situation in this field in China, based on 3651 papers published at home and abroad in recent 36 years, this paper analyzed the number of articles, sources of articles, cited frequency, main authors, research institutions and research hotspots, etc. The results showed that: (1) after 2000, the number of papers on desert steppe has increased greatly, with an average annual publication of over 160 papers, but the cited frequency of each paper, the number of high-quality academic journals and innovative research results were few, and the overall quality of papers needs to be further improved; (2) Innovative evaluation methods and theoretical research had always attracted much attention, and the comprehensive analysis of research progress in a certain field by using big data methods has been recognized by scholars; (3) Han Guodong, Song Naiping, Wei Zhijun, Zhou Guangsheng and others were the main contributors to desert grassland research. Inner Mongolia Agricultural University and Ningxia University have played an important role in the cooperation between publishing institutions and formed the core of research network. However, the cooperation between Chinese papers research institutions was more discrete than that of English papers, especially with foreign institutions; (4) The research focused mainly on the impacts of human activities and climate change on the vegetation-soil system of desert steppe, the productivity of desert steppe vegetation and its influencing factors, and the use of sporopollen to study vegetation and environmental changes. In the future, it is necessary to carry out more in-depth research from the meso-and micro-level to promote the output of high-impact and high-quality results, so as to provide more data support for the construction of ecological civilization and the development of science and technology in this region. It is expected that this paper can provide reference and new direction for the related research of desert steppe, and provide scientific basis for grassland construction and decision-making in China.should be strengthen cooperation and innovation between institutions and personnel at home and abroad, apply multi-disciplinary knowledge and multi-technical means from multi-scale and multi-dimensional, and strengthen the analysis and discussion of the interaction between human activities and climatic conditions on the evolution process of plant community structure, the coupling relationship between above-ground and underground ecological processes and the internal mechanism between different trophic levels in desert steppe. In order to promote the output of high-impact and high-quality results, and realize both quantitative and qualitative changes of scientific research results, and pay equal attention to basic research and practical application, it is expected that this paper can provide reference and inspiration for the relevant research of desert steppe, and provide scientific basis for grassland construction and decision-making in China.
