中国自然生态空间研究的知识图谱分析

为把握中国自然生态空间的研究热点、主要内容和前沿趋势,借助CiteSpace文献可视化分析工具,对1992—2018年中国自然生态空间研究的583篇文献进行关键词、发文作者和发文机构共现分析。研究表明:(1)中国自然生态空间研究的年度发文量经历了缓慢增长期、急剧增长期、波动增长期;(2)部分学者已经形成了相对固定的学术团队,但各学术团队之间较为独立,学者间联系较弱;(3)全国各机构之间发文数量的差异较大,其中位于西北和华北两个区域内的学术机构自然生态空间研究成果较多;(4)从突现关键词分析来看,随着时间的推移与国家政策的推进,学者们自然生态空间研究的对象也在改变;(5)中国自然生态空间的利用与生态环境保护、景观格局、生态系统服务功能价值评估等是中国自然生态空间研究的主要内容。未来时期内,中国自然生态空间研究应在实现研究方法综合应用的基础上,加强范围划定、分类体系、识别方法、用途管制研究,以期实现中国自然生态空间研究进一步发展。

Knowledge Graph Analysis of Natural Ecological Space in China

In order to grasp the research hotspot,main content and front trends of China s natural ecological space,583 documents of China s natural ecological space research from 1992 to 2018 were analyzed by using the Cite Space document visualization analysis tool.The results show that:(1)the annual volume of natural ecological space research in China has experienced a slow growth period,a sharp growth period and a fluctuating growth period;(2)some scholars have formed relatively fixed academic teams,but the academic teams are relatively independent,and the relationship between scholars is weak;(3)the number of papers published by institutions across the country is quite different,which the academic institutions in Northwest China and North China have more research achievements on natural ecological space;(4)according to the analysis of key words,the research objects of natural ecological space of scholars are also changing with the development of time and the promotion of national policies;(5)the main contents of China s natural ecological space research includes:the utilization of natural ecological space and the evaluation of ecological environment protection,landscape pattern and ecosystem service function value.In the future,based on the comprehensive application of research methods,China s natural ecological space research should strengthen the research on scope delimitation,classification system,identification method and use control,so as to realize the further development of China s natural ecological space research.
