Research on Standard Plot and its Application in Integration of Agricultural Land Classification in China

The paper tries to study the application of standard plot in integration of agricultural land classification. Method of systematic analysis was employed. The results show that regional comparability and national integration are vital to the implementation and achievement of scientific output of agricultural land classification in China. The meaning, types, principles and significance of standard plot were analyzed. Indicators for evaluating land quality of standard plot were proposed in order to construct national analogy system of standard plot. Finally, suggestions were made on the establishment and management of standard plot. In conclusion, it is realistic and feasible to set up indicator system for evaluating land quality of standard plot, to construct national analogy system, and to apply them to integration of national agricultural land classification according to relations between indexes for agricultural land classification of standard plot.
