中文摘要：

通过砂壤土人工土槽试验，对探地雷达技术在土壤剖面特征探测和土壤含水量测定方面的应用展开了研究。结果表明：通过对雷达图像的合理处理和解译，可以很好地获取土壤中异常体的位置特征信息；分析雷达波在土壤中传播速度的变化，明确基于探地雷达的土壤剖面平均含水量测定方法的适用性和准确性。为探地雷达技术在土壤学领域的应用提供了依据。

英文摘要：

In this paper, we explore the application of ground penetration radar on soil layers detecting and soil volumetric water content measurement through one sandy loamy soil trough experiment. The results show： the metal abnormities can be well identified after radargram filtered~ We confirm the accuracy and applicability of the ground penetrating radar to be used to estimate mean volumetric water content in soil profile after radar wave velocity analysis. Therefore, the study established an important base of the application of ground penetrating radar on soil science.
