摘　　要：探地雷达(Ground Penetrating Radar,GPR)作为一种快速、无损的中小尺度近地传感技术,因其具有信息量大、分辨率高、空间连续性好等优点在土壤性质探测中得到广泛应用。在系统介绍探地雷达在探测土壤性质原理的基础上,概述了正演模拟方法与目前应用广泛的土壤介电模型,归纳了探地雷达技术在土壤性质(土壤含水量、土壤质地、土壤层次、土壤压实、土壤盐分)探测中的应用研究现状。并讨论了该技术在实地应用中存在的问题与局限性:实地探测影响因子复杂,难以分离,数据解译复杂且具有主观性,大部分研究仅停留在定性或半定量阶段等。最后针对探地雷达在土壤学领域的应用情况,提出了其不足与展望:随着信号处理技术的不断发展与理论研究的日益成熟,探地雷达在土壤特性探测中仍然是一个有潜力的工具。旨在为探地雷达在土壤性质探测应用中的研究提供参考。Ground Penetrating Radar(GPR)is recognized for its rapid,non-invasive technology in medium and small-scale near-earth sensing.It has been widely applied in soil property analysis due to its considerable data richness,high resolution and excellent spatial continuity.This article presented a comprehensive review of the principles underlying GPR’s use in soil property detection,elaborated on forward simulation methods and the prevalent soil dielectric models in use.It summarized the current advancements in applying GPR technology for assessing various soil properties,including moisture content,texture,stratification,compaction,and salinity.Additionally,the paper discussed the challenges and limitations in the field applications:the influence factors of field detection were complex,and the data interpretation was complex and subjective,most of the researches only stayed in the qualitative or semi-quantitative stage.Concluding perspective,the article pointed out that with ongoing advancements in signal processing and theoretical research,GPR held significant potential for future innovations in soil characteristic exploration.This work aimed to serve as a valuable resource for ongoing and future studies on the application of GPR in soil property investigation.
