Abstract: Research advancements in soil environmental quality evaluation of agricultural land in China and other countries were reviewed. The evaluation standards and evaluation methods as well as the category classification were analyzed. From different evaluation scales of monitoring points, investigation unit and evaluation unit, and based on the degree of exceeded standard, cumulativity and security of agricultural products, the soil environmental quality evaluation procedure and methods of agricultural land were described in detail. Based on the multi-source data and multi-dimensional evaluation, the applicability of methods for category classification of soil environmental quality of agricultural land are discussed and presented for current soil management in China.

Key words: agricultural land, soil environmental quality, evaluation, category, classification
