On the Soil Quality Management——Soil Function and Soil Quality

土壤质量管理是对土壤功能、土壤质量、土壤退化、土壤修复及其关系的研究和成果应用的科学实践活动。各种土壤的不同功能有其空间分异、历史演替和强弱序列;土壤质量及其评价建立在土壤功能之上。本文阐述了土壤功能、土壤质量及其评价指标和方法,并对今后的土壤评价研究提出了建议。

The soil quality management is the scientific practice to study the soil function, soil quality, soil degradation and remediation, and their relationships, and the application of the obtained achievements. All soil＇ s functions have their spatial variations, historical evolution and strength differences. Soil quality research and its evaluation are performed based on the soil functions. In the thesis the soil functions, and the soil quality and its evaluation indexes and methods were discussed. And suggestion was proposed for further soil quality evaluation.
