A method for exploring of gradient geochemistry includes the following steps: densely collecting soil samples and gas samples along a longitudinal direction in a certain depth range of a superficial layer; collecting soil samples and gas samples in the range from 1 m to 50 m deep by a special drilling machine; after conventionally analyzing and processing the geochemical indexes, extracting and figuring the bathymetric curve and its gradient curve, the section curve and its gradient section curve along a certain direction, contour section and its gradient contour section of the various indexes, so as to process the data and to represent the figure in 3D. More plentiful information, especially the longitudinal change information, can be obtained by this method than by conventional geochemical exploration. Gradient prospecting is realized through the formed method prospecting the change of geochemical indexes with depth by collecting the samples along depth.
