Abstract:

Constructing a scientific, reasonable, and feasible land resource classification system is the premise and foundation for effectively carrying out land resources survey, correctly making land resource development and rehabilitation planning, and scientifically managing land resources. Based on the definition and connotation of land resource classification, this study compared six representative land resource classification systems internationally and eight land classification systems in China, analyzed the main problems of China’s current land resource classification system, and put forward some recommendations for improving the classification system of land resources in China. The results indicate that there are three main problems in China’s current land resource classification systems. First, the current systems may not be able to accurately reflect the complex and diverse land use types and the regional differentiation of land use due to the two land use classification levels and insufficient land use types, which compromises the actual application effect of land resource classification as a result. Second, land resource classification standards are sometimes confusing, with the form classification standards and functional classification standards coexisting in the same classification level and classifications lacking scientific and logical rigor. Third, the classification standards of some land use types are unclear, and some land use types have no corresponding categories in the classification systems, which is contrary to the principle of “no repetition and no omission” in land use classification setting. The following recommendations were put forward to improve the classification system of land resources in China. First, future revision of land resource classification system should adhere to the six basic principles of land use classification in China. Second, it is practicable to learn from the experience of the four levels of classification in the United Kingdom and the United States, and we put forward the basic framework of China’s land resource classification system with four levels. Third, it is necessary to upgrade the national land use classification standard system to national laws and regulations referring to Russian’s experience, and thereby comprehensively enhance the seriousness and authority of the national land resource classification system.
