国内近20年土地生态研究热点及展望——基于Ucinet的知识图谱分析

研究目的:对1998—2017年CNKI总库中文核心期刊和CSSCI关于土地生态研究的222篇文献进行可视化分析,分析当前土地生态研究热点,为把握研究趋势提供参考。研究方法:文献分析法、多维尺度分析、社会网络分析。研究结果:(1)国内土地生态研究视角多元,内容丰富,已形成一定的研究规模,但研究整体性和系统性有待进一步提升;(2)土地生态研究重点关键词主要包括国土资源、土地利用、模型与方法和生态安全等;(3)依据共词分析的知识图谱,将近20年国内土地生态研究热点主题概况为资源特征导向研究、管理导向研究、技术与方法导向研究、服务导向研究和社会经济导向研究。研究结论:加强土地生态领域基础理论研究,完善土地生态评价技术方法体系和推进土地生态监管体系构建将是未来土地生态领域的重点研究方向。

Land Ecological Research Hotspots in Recent 20 Years in China and Its Prospect: A Knowledge Map Analysis based on the Ucinet

The purpose of this paper is to analysis 222 literature on the land ecology from 1998 to 2017 in Chinese core journals of CNKI general library and CSSCI, to analyze the current land ecological research hotspots, and to provide reference for grasping the research trend. The research methods include literature analysis, multidimensional scaling analysis and social network analysis. The research results are as follows. 1)Research perspectives of land ecology in China are diverse and rich, and a certain scale of research has formed, but the study of generality and systematization needs to be further improved. 2)The keywords of land ecological research include land resources, land use, model and method, ecological security, etc. 3)Based on the knowledge map, the hot topics of nearly 20 years can be summarized as: resource-feature-oriented research, management oriented research, technology-oriented research, service-oriented research and social economic research. In conclusion, the future focuses of land ecological research directions are as follows: the land ecological basic theory research is expected to be strengthened; the land ecological evaluation methods system is expected to be improved; and the land ecological regulation system building is expected to promoted.
