土地整治和复垦施工中大型机械作业会造成土壤的过度压实，影响整理后土地的生产力。论文研究使用400MHz和750MHz探地雷达探测非饱和水分条件下土壤的压实度，选取表征电磁波传递信息的介电常数，对介电常数有较大影响的土壤含水率、土壤压实度作为考虑因子，分析在多个因子共同作用下介质介电常数的变化规律。利用探地雷达检测土壤压实度信息的研究具有较高的创新性、准确性可行性，对无损获得土壤压实度信息有一定的理论价值和借鉴意义。

A lot of mechanical work in land remediation and reclamation construction would cause the soil compaction excessivly increase, it will reduce the productivity of land. This thesis study used 400 MHz and 750 MHz Ground penetrating radar (GPR) to detect unsaturated water under the condition of the soil compaction degree, selecting dielectric constant as the characterization of transfer information of electromagnetic wave,selecting soil moisture content, soil compaction which has large inlfuence on dielectric constant as consideration. Analysis the change rules of dielectric permittivity under the action of multiple factors. The research using Ground penetrating radar (GPR) to detect soil compaction degree information is high creativity, feasibility, accuracy and it also has the certain theory value and signiifcance to get nondestructive soil compaction degree information.
