标准摘要
[中文适用范围]： 本标准给出了非饱和区土壤水物理学的简化理论，并定义了非饱和区土壤物理调查领域中使用的一组术语、数量、单位和符号。 本国际标准仅适用于 ISO/TC 190 中详细阐述的非饱和带（包括膨胀土）土壤物理调查标准。 本国际标准特别排除大孔隙流。 [外文原描述]： ISO 15709:2002 gives a simplified theory of the physics of soil water in the unsaturated zone and defines a set of terms, quantities, units and symbols used in the field of soil physics investigation of the unsaturated zone. ISO 15709:2002 is applicable only to standards on soil physical investigations of the unsaturated zone (including swelling soils) elaborated within ISO/TC 190. ISO 15709:2002 specifically excludes macropore flow.
英文名称Soil quality — Soil water and the unsaturated zone — Definitions, symbols and theory
