This standard specifies the soil names and codes for the soil order, suborder, soil class, subclass, soil genus and soil species in the Chinese soil classification system. This standard applies to the identification of soil information in the process of soil survey, soil statistical information summary, soil information exchange and processing, and soil resource utilization.

This standard specifies the soil names and codes for the soil order, suborder, soil class, subclass, soil genus and soil species in the Chinese soil classification system. This standard applies to the identification of soil information in the process of soil survey, soil statistical information summary, soil information exchange and processing, and soil resource utilization.

GB/T 17296—2000
This standard is one of the important basic standards of the national information system. This standard is compiled based on the research results of the second national soil survey. It extends and refines GB/T17296-1998 "China Soil Classification and Code Soil Order, Suborder, Soil Class and Subclass Classification and Code". On the basis of the first four levels of soil classification code, soil order, suborder, soil class and subclass, two levels of soil genus and soil species are added and coded.
Since this standard completely covers GB/T17296-1998 in terms of content, this standard will replace GB/T17296-1998 from the date of implementation.
This standard is proposed and managed by the China Standards Research Center. The drafting units of this standard are: China Standards Research Center, National Agricultural Technology Extension Service Center, and Soil and Fertilizer Research Institute of the Chinese Academy of Agricultural Sciences.
The main drafters of this standard are Li Xiaolin, Sui Pengfei, Zhang Shiyan, Huang Hongxiang, Zhao Yanhua, Feng Wei, Wang Rongfang and Tian Youguo. 701

This standard specifies the soil names and codes for the seven classes, subclasses, soil types, subclasses, soil genera and soil species in the Chinese soil classification system. This standard is applicable to the identification of soil information in the process of soil survey, soil statistical information summary, soil information exchange and processing, and soil resource utilization. In application, it can be intercepted and used at different levels according to different needs, or expanded based on the coding structure of this standard.
2 Classification principles and methods
This standard is based on the basic principles of information classification such as scientificity, integrity, systematicity, scalability and compatibility, and uses the line classification method to divide the classification units of the soil classification system into six levels: soil order, suborder, soil class, subclass, soil genus and soil species. 3 Code structure and coding method
3.1 Code structure
This standard uses the hierarchical coding method to code the soils of each level in the Chinese soil classification system. The code structure is as follows: 区区XX
Sixth layer (two Arabic numerals)
Fifth layer (two Arabic numerals)
Fourth layer (one Arabic numeral)
-Third layer (one Arabic numeral)
Second layer (one Arabic numeral)
First layer (one uppercase English letter)
3.2 Coding method
According to the above six-layer eight-digit code structure, the specific coding method of China's soil code is as follows: soil order code is represented by one uppercase English letter in the first layer; sub-order code is represented by soil order code plus one Arabic numeral in the second layer; soil class code is represented by sub-order code plus one Arabic numeral in the third layer; sub-class code is represented by soil class code plus one Arabic numeral in the fourth layer; soil genus code is represented by sub-class code plus two Arabic numerals in the fifth layer; soil species code is represented by soil genus code plus two Arabic numerals in the sixth layer. 3.3 Other Notes
3.3.1 Meaning of the number 0 in the code
Approved by the State Administration of Quality and Technical Supervision on June 9, 2000702
Implementation on March 1, 2001
GB/T17296—2000
In the unsubdivided taxonomic unit, the coding expression of the lower class is represented by the code of its upper class plus 0, and the name of the lower class remains unchanged. For example: the alkaline soil subclass is not subdivided into soil classes, and the coding expression at the soil class level is represented by the alkaline soil subclass code K2 plus one 0, in the form of K20, and the name of the soil class remains unchanged, still called "alkaline soil"; for another example: the subclasses and soil genera below the cold frozen soil class are not subdivided, and the coding expression at the subclass and ten-genus levels is represented by the cold frozen soil class code M41 plus 0, in the form of M410 and M41000 respectively, and the name remains unchanged, both called "cold frozen soil".
The coding order of the two-digit code structure of soil genus and soil species starts from 11 (except for soil genus that are not subdivided below the sub-class), and avoid using codes with the second digit of 0 such as 20, 30, 40. 3.3.2 Prefixed place name of soil species
In order to avoid the same name for different soils, this standard adds the place name of the location where the typical profile is sampled in front of the original name of some soil species. 3.3.3 Treatment of soil species not clearly included in the code table In the soil species level, all soil species that are not clearly included in this standard can be treated in the following two ways: one way is to include them in the code with 99 as the last digit under the soil genus to which they belong, for example, code .1111199 represents various "other tidal mud fields" soil species in the tidal mud field soil genus that are not clearly included in this standard; the other way is to add a new code after the soil species code given in this standard, for example, L1111144 can be added with L1111145, I.1111146, etc., but its scope of use is limited to the internal use of its own system. 4 Classification code table
