Abstract:Driven by modern development modes, the diversified transfer of traditional agriculture has been giving rise to the increase and reconfiguration of national economic activities, as well as the promotion of yield and quality of agricultural produce, and the living standards. This change has also further changed the rationality of the classification of agricultural land types under the "big agriculture" mode and the definition of the relationship between classification and national economic industry and the nature of land use. In this paper, historical factors and industrial environment that cause the continuous changes in the definition of agricultural land have been studied based on the changes in the scope of agricultural industry and its impact on agricultural land, the basis of the classification of agricultural land by the soil tillage layer, the differences between traditional agricultural land and current industrial classification of national economy. Combining with these research results, targeted suggestions has been put forward to ensure more rational division of agricultural land.
