摘要： 对气量失重法、气量体积法和烘干法3种土壤水分测定方法的测定结果进行比较。结果表明，气量体积法与烘干法测定结果相比有较大差异，气量失重法与烘干法测定结果基本吻合，并分析气量体积法和气量失重法测定结果产生偏差的原因。

Abstract: A comparison of measuring soil moisture with gas content weightless method，gas content volume method and gravimetric method was made．It showed that the measuring result of gas content volume and gravimetric method is difference，the measuring result of gas content weightless and gravimetric method is similar，and analyse the reason of deviation.The results indicated that gas content weightless is accurate and reliable to measuring soil water content．
