借助三维自然电位电源密度反演成像方法,分析南京中山植物园试验场地的野外电位观测资料,研究包气带的介质结构信息。研究结果证明,电源密度反演成像结果与探地雷达获得的地下介质结构特征具有很好的吻合性,这表明三维自然电位电源密度成像可以应用于探测包气带介质结构。这为研究地下空间结构提供了一种新的地球物理方法。
Based on three-dimensional current source inversion tomography,the authors applied the self-potential data obtained in the research site of Zhongshan Botanical Garden in Nanjing to study the medium structure in the vadose zone. The medium structure revealed by current source tomography accorded with the results from ground penetrating radar. This indicates that three-dimensional current source tomography can be used to detect the medium structure in the vadose zone,thus providing a new geophysical method for investigating ground medium structure.
