土地集约利用知识图谱研究

Researches on Knowledge Mapping of Land Intensive Use

土地集约利用研究一直是土地相关学者研究的热点,然而由于研究领域广泛,近些年研究的热点变化不一,研究趋势不明。本文以1967年～2014年期间Web of ScienceTM数据库为文献源,选择信息可视化分析软件CitespaceⅡ,综合信息可视化、文献计量方法和数据挖掘算法,从多元、分时、动态的视角出发,在识别土地集约利用研究的经典理论及知识聚类以及演进脉络的基础上,探究了土地集约利用研究的前沿热点及未来延伸趋势,从而构建了一个土地资源研究的理论库,为相关学者提供理论参考和借鉴。研究表明：11996～2014年期间,土地集约利用研究相关的文献和被引文献数量稳步增长,但是近两年论文发表频率有所下滑;21967年～2014年间,土地集约利用研究全面爆发,研究主题全面扩展,虽然2003～2014年间研究关键词数量大幅度减少,同质化明显,但2003～2014年的研究主题步入全新阶段;3信息科技高速发展背景下,土地集约利用评价方法成为热点,但是对环境效应问题重视不够,集约用地技术研究不足。

Study on the intensive use of land has always been a hot spot of land- related research,but because of the broad field of study,in recent years,the research focus varied,and trends are unknown. Therefore,papers of 1967- 2014 period in Web of ScienceTMdatabase and Citespace II information visualization and analysis software are used to mine the land intensive use in scientific literature,integrated information visualization methods,statistical methods and the data mining algorithm,from the perspective of multiple,time-sharing,dynamic. Based on land intensive use classic theory,knowledge clustering and evolution rule,the research front,hotspot and its extending tendency are expolred to bulid a theory base in the land resource research field for related scholars. Studies have shown that： 1 Land intensive utilization of relevant literature and cited literature number during 1996 ～ 2014 have steady growth,slow but over the past two years; 2During 1967 ～ 2014,study on the intensive use of land have fully brown,the research theme was fully extended,although number of research keywords significantly reduced between 2003 ～ 2014,homogenization of papers are apparent,but subjects entered a new phase;3Under the background of rapid development of information technology,evaluation of intensive utilization of land become the hot,but insufficient attention to the effects on the environment,and lack of intensive land use research.
