摘要: 保持和提高土壤质量是实现农业可持续发展的基础.为此,必须清楚土壤质量的概念以及土壤质量的评价方法.本文综述了土壤质量的概念及其研究进展.土壤质量评价要以土壤的功能为基础,不同土壤的评价应采用不同的标准,土壤质量的评价是相对的而不是绝对的.介绍了国际上几种常用的土壤质量评价的方法.并对耕地土壤质量评价的指标选择进行了探讨.

Abstract: 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 indictors was discussed.

Key words: Soil quality, Evaluation principle, Evaluation method, Soil quality indices, stage water consumption, vertically rotary sub-soiling tillage, profit, potato, tuber yield, semiarid northwest Loess Plateau
