After reviewing recent study of the purposes, principles, methods of appraisal of agricultural land in China a conclusion can be drawn that the purposes of appraisal of the land are identified and consentient by all reseachers; that the principles of gradation and classification of the land are integrated and complete, but that the principles of evaluation of the land are not set up yet and the study of gradation methods for the land is nearly blank. Though the concept and technical route of gradation of the land are prescribed in 《The regulations on gradation and classification of agricultural land》 and much work has been done in the study and practice of classification of the land, but little in the study of how to integrate classification and evaluation of the land.Though extensive study has been done on evaluation methodsmost of the work just follow the ways to evaluate urban land. Presently how to be innovative in the study and how to establish a countrywide grading and pricing system for agricultural land is urgent task.
