基于CiteSpace中国土地集约利用评价研究的知识图谱分析

The Knowledge Map of Land Intensive Use Evaluation Research in China:An Analysis Based on CiteSpace

基于CiteSpace文献可视化分析工具,对2000—2017年中国知网中"核心期刊"和"CSSCI"数据库关于中国土地集约利用评价的688篇研究文献进行梳理分析,分别绘制出研究作者、研究机构和关键词的知识图谱。结果显示:目前土地集约利用评价研究处于稳定发展时期,经过长期的发展,已形成了相对完整的学科体系;研究作者和机构之间的交流合作有待进一步加强,共线网络需要巩固;土地集约利用评价研究主要围绕"集约利用"、"时空分异"、"城市土地"、"评价指标"等高中心性的节点展开,并由此辨识出各个阶段土地集约利用评价的研究热点;根据关键词分类,从评价方法、评价指标体系、研究对象和研究地区等方面阐述土地集约利用评价的研究状况;土地集约利用评价研究需立足现有薄弱点,加强理论研究、方法创新和评价指标体系构建,为我国未来土地集约利用领域的深入研究提供借鉴和指导。

Based on CiteSpace literature visualization analysis tool,the 688 research papers on the evaluation of China's land intensive use in the “core journals” and “CSSCI” databases in China Knowledge Network from 2000 to 2017 were analyzed,the knowledge maps of research authors,research institutions,and keywords are drawn separately.The results show that: at present,land intensive use evaluation research is in a stable development period,after long-term development,a relatively complete discipline system has been formed;exchanges and cooperation between research authors and institutions need to be further strengthened,and the collinear network needs to be consolidated;land intensive use evaluation mainly focuses on high-central nodes such as “intensive use”,“time and space differentiation”,“urban land” and “evaluation indicators”,and thus identifies the research hotspots of land intensive use evaluation at various stages;according to the keyword classification,the research status of land intensive use evaluation is obtained from the evaluation methods,evaluation index systems,research objects and research areas;land intensive use evaluation research needs to be based on existing weak points,strengthen theoretical system improvement,method innovation and evaluation index system construction,and provide reference and guidance for the in-depth study of future land intensive use in China.
