| 摘 要： | 吉林西部盐碱地区的探地雷达调查表明,盐碱地与耕地土的雷达回波具有明显差别,根据振幅的衰减特征可以精确区分耕地与盐碱地,根据频谱中高频峰值与土壤有机质含量的相关性可定性评价土壤的盐碱化程度.在雷达瞬时振幅图上,可将盐碱地纵向剖面分为盐分积累带和过渡带.采用探地雷达方法可快速了解盐碱化程度在深度方向上的变化,适宜开展大面积地面调查.

| Abstract: | The result of GPR investigation in west Jilin shows that the radar waveform of saline-alkali soil is different from that of tillable soil, and this can be used to distinguish tillable soil from saline-alkali soil. The extent of salinization can be determined according to the relativity of spectra. The saline-alkali accumulated part can be distinguished from the transitional part of saline-alkali soil according to instantaneous amplitude of GPR record. So the GPR integrated with geochemical means can interpret the salinization degree in depth rapidly, and can also be used in large-area surface survey. |
