摘    要:对用TDR法、中子法和重量法测得的土壤水分含量观测值的比较结果表明,随着土壤深度和测量时间的变化,中子法的平均测定误差为3.76%,TDR法为3.59%。并且这2种方法的土壤水含量观测值的时空变化和重量法具有相同的趋势。因此,用TDR法测定土壤含水量与用中子法是同样可靠的。

关 键 词:TDR法 中子法 重量法 土壤水分 测定

Abstract:A comparison of measuring soil water content with oven dry, neutron probe and TDR was made It showed that the mean error in soil depth and time of neutron probe measurement was 3 76% and that of TDR was 3 59% Soil water dynamics simulated with the regressive equations built with data measured with neutron probe and TDR were similar The result showed that it was reliable to measure soil water content both with neutron probe and TDR
Keywords:TDR  neutron probe  oven dry  soil water content  comparison
