中国土地评价研究知识图谱——基于CiteSpace的计量分析

Progresses and Perspectives of Land Evaluation Research in China based on Cite Space Quantitative Analysis

利用CiteSpace可视化文献分析软件,运用比较分析法、计量分析法对1981~2015年CNKI总库中文核心期刊和CSSCI中文社会科学引文数据库中土地评价研究的993篇文献进行可视化分析,得出当前土地评价研究热点、作者群以及主要研究机构的知识结构图谱。研究结果表明:(1)1981年以来,中国土地评价研究主要围绕"土地利用"、"土地适宜性"、"土地类型"、"土地分等定级"、"土地可持续利用"、"土地适宜性评价","土地集约利用"等展开;(2)傅伯杰、杨敬锋、周勇、陈志民、林培、倪绍祥等是主要发文作者;(3)中国土地勘测规划院、武汉大学资源与环境科学学院、中国科学院南京土壤研究所、北京林业大学水土保持学院以及河南省科学院地理研究所是主要的研究机构;(4)《中国土地科学》是土地评价相关研究刊载论文数量最多的期刊,《中国土地》、《农业工程学报》以及《资源科学》是刊载土地评价研究论文重要的核心期刊。除了传统的土地评价视角下,土地利用、土地资源、地理信息系统、土地质量、土地适宜性、土地类型、适宜性评价等问题仍是中国土地评价研究的热点方向。最后,本文提出了未来土地评价领域的研究趋势。

The purpose of this paper was to examine 993 papers related to land evaluation from ＂China Knowledge Resource Integrated Database＂ and ＂Chinese Social Sciences Citation Index＂.The knowledge maps of research hotspot,the core of author groups,major research institutions and important academic journals were drawn by using visual document analysis software CiteSpace.The comparative analysis and quantitative analysis were used in this study.The results indicated that（1） the studies of land evaluation focused on land use,land suitability,land type,land classification and gradation,sustainable land use,land suitability evaluation,and land intensive use,etc.;（2） Fu Bojie,Yang Jingfeng,Zhou Yong,Chen Zhimin,Lin Pei,Ni Shaofeng et al.,were the top six prolific authors in the field of land evaluation;（3） Chinese Academy of Land Survey and Planning,College of Resources and Environmental Sciences,Wuhan University,Nanjing Institute of Soil Science,Chinese Academy of Sciences,College of Soil and Water Conservation,Beijing Forestry University and Institute of Geography,Henan Academy of Sciences were the major research institutions;（4） China Land Science published the largest number of papers on land evaluation;China Land,Journal of Agricultural Engineering and Resources Science were the main core journals of land evaluation.Finally,this study proposed the research orientation of land evaluation in China.
