It is significant to study the unified soil texture classification system.【Method】In view of the chaos phenomenon of using soil texture classification systems in China, the study introduces some important standards for grading of soil particles prevailing home and abroad, compares the characteristics of four soil texture classification systems, and retrospects the use of the experiment-CCCP’s Kazhinski system during the first phase of the Second National Soil Survey of China and the shift to the international system later, with focus on comparison of the standards for soil texture classification adopted by the nation and various departments in the country. 【Result】Nowadays, there is no such a soil texture classification system that can universally be used in China.【Conclusion】It is, therefore, recommended to use the American system . %R 10.11766/trxb201803120129 %U http://pedologica.issas.ac.cn/trxb/home %1 JIS Version 3.0.0
