摘　　要：探地雷达是一种快速、无损的测量土壤含水量的方法,且具有较高分辨率。本文介绍了四种探地雷达测量土壤含水量的方法,包括:多偏移距法、共偏移距法、钻孔雷达法和雷达信号属性法。文中详细阐述了每种方法的基本原理,并讨论了他们的可能性、优缺点、局限性和测量误差等。Ground penetrating radar（GPR） rapidly provides high resolution data on soil water content.This paper presents a comprehensive review of the basic principle of GPR and four methods for soil water content assessment,which are multi-offset methods,common offset methods,borehole GPR methods,and GPR signal attribute methods.For each of these four methods,we discuss the basic principles,illustrate the quality of the data with practical examples,and discuss the possibilities,limitations and errors.
