It is easy to the understanding of technical staff of the same trade：
Such as Fig. 1-3,1-6 is marked to be respectively in figure：Polluted area 1, planar detection unit region 2, survey line 3, uncontaminated region 4,
Detecting electrode 5, detection cable 6.
Embodiment 1：As shown in figure 1, the present embodiment is specifically related to a kind of Polluted Soil based on three-dimensional high-density resistivity method
Detection method, the method is comprised the following steps：
As shown in figure 1, in the arrangement planar detection unit of Polluted area 1 region 2, and arrangement is surveyed in planar detection unit region 2
Line 3；In the present embodiment, Polluted area 1（In Fig. 1 in dotted line circle）The number in interior planar detection unit region 2 is one, planar
Uncontaminated region 4 of the coverage of detection unit region 2 comprising Polluted area 1 and the outside of Polluted area 1（Dotted line circle in Fig. 1
Outward）.
In the present embodiment, survey line 3 includes the detection electricity that equally lattice-like is distributed in planar detection unit region 2
