列举书刊中关于土壤水含量的表述及方程式,指出其表述及方程式的疏漏和错误之处。认为：土壤水含量以质量计的应称为土壤质量含水量或土壤水土质量比,采用量符号ξ;以体积计的应称为土壤体积含水量或土壤水体积分数,采用量符号φ。分别给出了规范的量方程式和数值方程式。“,”This paper enumerates definitions and equations of soil moisture content in books and periodicals,and pointed out their oversights and mistakes.It is suggested that the soil moisture content measured by mass should be called the mass soil moisture content or the mass ratio of moisture to soil and symbolized with the quantity mark ξ;that measured by volume should be called the volumetric soil moisture content or the volume fraction of moisture and marked with φ.The standard quantity equation and the numerical value equation are provided respectively.
