There are miscellaneous kinds of soil group and soil associations with large areas in China. Jn order to use soil resources fully and propery, we have to study soil regionization in the whole China.Looking back on it, we can divide our study into several stages.(1)primary stage-1930's to 1940's.(2)progressed stage-from the begining of 1950's to the mid-1960's,(3)stagnated stage-from mid-1960's to mid-1970's,(4)New developing stage-from mid-1970's to the present.The study of sail regionization in whole China provided the scientific foundation for natural regionization and agricultural regionization and brougt about a great advance in agricultural production. The theory about soil regionization which has developed in the past years,couldn't fit the development of modern agriculture. Much remains to be done.we shoud pay more attention to the study of soil regionjzation jn the whole China.
