土壤质量含水量(g/kg)=θm =水分质量(g)/烘干土质量(kg) (2)容积含水量:容积含水量(volumetric water content)指单位容积的土壤中,水分容积所 占的分数和百分数,无量纲,常用符号θv 表示。它表明土壤中水分占据空隙的程度。

Respiration rate and soil moisture are positively correlated when soil volumetricwatercontent under 20% and negatively correlated when its content above 20%.
当土壤体积含水量低于20%时土壤呼吸速率与之成正相关;若超过20%后土壤呼吸速率与之成显著负相关。
