[Soil quality and its evaluation].
Preservation and improvement of soil quality is the basic task for agricultural sustainable development. For this reason, the concept and the evaluation method of soil quality should be clearly understood. In this paper, the concept of soil quality and its advanced researches were reviewed. Soil quality evaluation should be based on soil function, different types of soils should be evaluated by different criterions, and soil quality evaluation should be relational rather than absolute as well. Some methods of soil quality evaluation were introduced, and the selection of evaluation indicators was discussed.
