基于文献定量分析的我国沙化土地治理研究

Research on desertification land management in China based onquantitative analysis of literature

对我国沙化土地治理研究领域1980-2019年发表的文献进行统计,运用文献定量分析法,借助Noteexpress3.2软件,揭示了该研究领域近39年来文献在数量、核心作者、研究机构及关键词方面呈现的规律,据此对我国沙化土地治理措施进行了总结,分析了各类措施的特点和适用区域,并对该领域未来研究的发展提出了建议。研究结果表明:①我国沙化土地治理研究领域的文献数量呈现逐年递增的趋势,符合二次函数递增模型,且在未来一定时期将会保持持续增长态势;②该领域的核心作者群和核心文献流尚未形成,作者大多为瞬时研究者;③沙化土地治理核心研究机构较少,高等院校和科研院所是沙化土地治理研究的核心力量;④从关键词分析来看,沙化土地的成因、治理对策、修复技术、动态变化是研究的热点;⑤目前我国沙化土地治理的措施主要有五大类,即生态建设措施、物理修复措施、生物修复措施、化学修复措施以及联合治理措施。

on the statistics of literatures published in the field of desertification land governance in China from 1980 to 2019,this paper uses the method of literature quantitative analysis,with the help of noteexpress3.2 software,to reveal the law of literature in the field of desertification land governance in recent 39 years in terms of quantity,core authors,research institutions and key words,and then summarizes the measures of desertification land governance in China,and analyzes the characteristics of various measures The research results show that:the number of literatures in the field of desertification land governance in China is increasing year by year,which conforms to the quadratic function increasing model,and will continue to increase in a certain period in the future;the core author group and core literature flow in this field have not yet formed,and most of the authors are instantaneous Researchers;there are few core research institutions of desertification land governance,and universities and scientific research institutes are the core forces of desertification land governance research;from the perspective of key words analysis,the causes of desertification land,governance strategies,remediation technology and dynamic changes are the hot spots of research;at present,there are five main types of desertification land governance measures in China,namely ecological construction measures,physical remediation measures Bioremediation measures,chemical remediation measures and joint governance measures.
