| 摘 要： | 基于土壤湿度电阻法测量基本原理,设计了一种通过直接测量土壤电阻获得土壤含水量的测量装置,对甘肃旱地黄土土壤含水量与土壤电阻关系进行试验研究,揭示了黄土土壤含水量与土壤电阻关系的基本变化规律,通过对实测值进行拟合得到黄土土壤含水量与土壤电阻关系的数学模型。结果表明:在土壤质量含水量w≥8.5%时,土壤电阻值与土壤含水量的关系稳定且重复精度高;当w<8.5%时,随着土壤含水量的减小,土壤电阻值急剧增加。

| Abstract: | Based on the principle of electrical measurement of soil moisture,a kind of equipment was designed which could get soil moisture through the direct measure of soil resistance.Experimental research on the relation between soil moisture and soil resistance of dry loess in Gansu were carried out to obtain the change laws between moisture and resistance of dry loess by using this equipment.A simulation model on the relation between soil moisture and soil resistance was developed.Result of experiment showed the stable relation and high repeat precision between soil moisture and soil resistance when soil moisture w≥8.5%,and soil resistance increased quickly along with the diminishing of soil moisture when soil moisture w<8.5%. |
