| 摘 要： | TDR作为1种野外测量土壤水分量简便而准确的方法而被人们熟知和使用。本研究使用TDR在河套灌区对冻土在冻结融解时进行了土壤水分测定。为了用TDR数据计算冻土的液态水分量,文中分析了众多计算模型和经验模型,最终找到了最适合本地区土壤特性的B irchak模型。 |
| 关 键 词： | 校正 TDR数据 冻土 Birchak模型 |

| Abstract: | As a rapid and accurate method Time Domain Reflectometry (TDR) is widely used to determine volumetric water content from apparent measured relative dielectric constant , ε. TDR measurement was applied in Inner Mongolia Hetao Irrigation District of China both in warm season and cold season. For obtaining unfrozen water content, the liquid water was divided into free water and bound water to make calibration using Birchak model. Because of the similarity of dielectric property of bound water and ice, Birchak model was applied to evaluate unfrozen water content in frozen soil. |
| Keywords: | Calibration TDR data frozen soil Birchak model |
