基于科学计量学的中国土地科学发展分析

研究目的:对"中国知网"刊载的土地科学期刊文章进行计量分析,探讨土地科学发展特征。研究方法:科学计量学、网络分析法。研究结果:通过对1980年1月1日至2016年12月31日中国知网土地科学文献题录数据的处理分析,可以刻画土地科学研究现状,梳理土地科学发展脉络和演进逻辑。研究结论:(1)土地科学影响力逐步攀升,并已形成了稳定的学者群体,新一代学者逐渐开始引领土地科学发展方向。(2)土地科学主要研究机构多为高等院校和中国科学院等科研院所,研究活动分布具有显著的空间集聚性。土地科学研究基金资助力度持续增加,文章来源期刊多元化。(3)土地科学发展经历了土地制度探索阶段、耕地保护阶段、城镇化阶段、城乡统筹发展阶段。"人地关系权籍时空系统"理论和时空锥理论构成了土地科学演进的内在逻辑。(4)"人地权三位一体"理论和三维空间研究域模型及其理论构成了土地科学研究域的基础,即土地科学主要研究内容是解决在特定发展阶段,土地生产关系与土地生产力不匹配所衍生的土地利用问题,而土地政策研究、土地资源利用和管理研究、工程技术研究则是解决相关问题的土地科学理论实践,土地科学是一门典型的"问题导向型"和"实践推动型"的科学。

Scientometric Study on Land Science Development in China

The purpose of this paper is to conduct a scientrometrics study based on the research published by CNKI from 01.01.1980 to 31.12.2016 and to explore the development characteristics of land science. The methods of scientrometrics and network analysis are employed. The results are as follows: the status of land science development is delineated and the development path and evolution logic of land science are exhibited through processing the bibliographic data. In conclusion, the influence of land science is rising steadily with a stable scholar group formation. New-generation scholars have gradually led the development of land science. The major research institutes of land science are the universities and Chinese Academy of Sciences, and the distribution of land science research activities is featured by a significant spatial accumulation. The sources of journal articles are diverse, and the funds are becoming more substantial. The development of land science experienced the land institution exploration stage, farmland protection stage, urbanization stage, and rural-urban integrated development stage. The theories of the spatio-temporal system of human-land relationship based on cadastre and property right as well as the spatio-temporal cone compose the internal logic regarding land science evolution. The theories of the integration for human-land-right as well as the triple dimensional space research model compose the research domain basis of land science. That is to say, the main content of land science research is to solve the land use problems resulted from the mismatch between land production relationship and land productivity in a certain stage. The research of land policy, land use and land management applies land science theory to solve the problems in practice, and land science is both a problem-oriented and practice-driven science.
