土地科学学科独立性研究——兼论土地科学学科体系研究思路与框架

研究目的:研究探讨并确定土地科学学科是否具有独立学科的本质属性,在此基础上提出土地科学学科体系研究思路与框架。研究方法:根据《中华人民共和国学科分类与代码国家标准(GB/T 13745-2009)》的定义,依据科学学方法,从讨论土地科学学科有无不可替代的核心理论和不可替代的研究域入手,研究土地科学学科的独立学科属性。研究结果:土地科学学科是一门具有不可替代的土地权籍核心理论,并与土地租价、土地可持续利用理论共同构成有机联系不可分割的核心理论轴,同时具有不可替代的3维3层3环耦合空间研究域的独立学科。研究结论:(1)借助逻辑和空间分析方法,提出的土地科学学科3维3层3环耦合空间研究域,揭示了土地科学学科的本质属性,从而解开了有关土地科学学科的多个重大难题。(2)通过有关土地科学学科发生、演进和发展趋势的研究分析,揭示了:1土地科学学科与相关学科交叉的本质,是由于人类不断提高土地生产力的内生要求牵引,引致土地科学学科研究域内生性扩张导致的交叉;2土地科学学科研究域是一个随着人类提高土地生产力而对应扩张的3维3层3环耦合空间域,且仍会伴随人类不断提高土地生产力的要求持续扩张。(3)通过有关不可替代核心理论及核心理论轴,3维3层3环耦合空间研究域及其形成,学科发生、演进和发展趋势的研究分析,提出了有关土地科学学科的完整系统学说。

The Disciplinary Independence of the Land Science and a Framework for Developing the Land Science Discipline

The purpose of this paper is to discuss whether the land science can be classified as an independent discipline, and propose a general framework for developing the land science discipline. The method uses a normative analysis to show the independence of the land science regarding the irreplaceable core disciplinary theory and core range of study according to the National Standard of Disciplinary Classification and Coding of People’s Republic of China（GB/T13745-2009）.The results show that the irreplaceable core theory of land science discipline （i.e., the land cadaster and property right theory）, linking with land rent and land sustainable use theories, together forms the core theoretical pillar of the land science systematically and inseparable. The land science discipline also has irreplaceable core range of study, i.e., the special character of three dimensions and three layers and three rings of land uses. The paper concludes that 1） the nature of land science can be reflected from the proposed three dimensions and three layers and three rings of ranges of study, which also helps to explain several important difficulties of land science discipline. 2） The interdisciplinary nature of land science and relevant disciplines is driven by the increased land productivity due to human beings activities. Furthermore, the interdisciplinary ranges of study will dynamically expand along with the expansion of scope of the human beings activities on land productivity. 3） A systematic land science discipline development framework has been proposed based on the discussed pillar of irreplaceable theories and ranges of study and the analysis on the occurrence, evolution, and development trend of the land research.
