This standard is entrusted to the China Land Surveying and Planning Institute for interpretation. GB/T19231—2003
The standardization of terms is the basis of standardization activities. In order to promote the construction of land science disciplines, improve the scientific nature of land management work, and strengthen international cooperation and exchanges in the fields of land science and land management, this terminology standard is specially compiled to scientifically unify and standardize land terms in land science and land management work. This standard is divided into six chapters: land, land use, land economy, land law, land survey and land management. The scope and principles of this standard:
a) The scope of word selection is mainly based on basic terms that can cover the main contents in the field of land science and land management; b) Terms that have been clearly defined in relevant disciplines such as geography, soil science, geology, ecology, surveying, economics, and law are not included;
c) In terms of time and space, the terms are limited to those used on the mainland after the founding of the People's Republic of China. Some terms that have been used in history and are used in Hong Kong, Macao, Taiwan and foreign countries but not used in China are not included. In principle, the terms in this standard are only given one English corresponding word. If there are several English corresponding words, only two are listed, and the authoritative works shall prevail.
