The method proposed in this paper is based on the use of land quality geochemical survey data and the collected comprehensive information on agricultural land environment to accurately classify the land grades in Linxia, Gansu. Taking the agricultural landform and yield per mu as macro-level indicators, the authors used the soil traits, soil nutrients, land cleanliness and life-health elements as micro-indicators to decompose, quantify and assign various indicators. The authors objectively and comprehensively used the new viewpoints of macro-index grading and micro-level grading, established cadastral archives of agricultural land quality survey, and provided an important basisfor land management decision-making.
