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 purpose of soil impedance measurement and the general method of measurement are introduced. The theoretical background and indoor and outdoor operation steps and data processing methods for measuring soil impedance coefficient of sandy forest with Yokogawa Type 32 4 4 (specificearthresistanceter) . The results show that it is feasible to use 32 4 4 earth resistance meter to measure the soil impedance coefficient of sandy forest with Wenner method. The results of this study have some application in the stratification of soil, the determination of surface soil moisture, and the preliminary determination of groundwater level prospect.
