沙质林地土壤阻抗系数测量方法

Method for the measurement of soil resistivity in sandy woodland.

介绍了土壤阻抗系数的测量目的及测量的一般方法 ;重点描述了应用大地阻抗仪 (YokogawaType 32 4 4 ) (specificearthresistancetester)测量沙质林地土壤阻抗系数的理论背景和室内、外操作步骤与数据处理方法。结果表明 ,使用 32 4 4大地阻抗仪 ,即运用Wenner法测量沙质林地土壤阻抗系数是可行的 ,其测量结果在对土壤分层、确定表层土壤含水量、初步确定地下水位等具有一定的应用前景。

The purposes and methods of soil resistivity measurement were introduced in this paper.Particularly,the theoretical background,field operating steps and data processing method of soil resistivity measurement using specific earth resistance tester (Yokogawa Type3244 Japan) were explained with the example measurement in sandy woodland.The results showed that method using the 3244 specific earth resistance tester,based on Wenner principle,to measure the sandy woodland soil resistivity was feasible.The measured results of soil resistivity have a certain application prospect in sandy soil delamination,soil water content prediction and the underground water table determination.
