A method for geochemical gradient exploration includes the steps of: 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 meter to 50 meters deep by a special drilling machine; after analyzing and processing the geochemical indicators, extracting and figuring the bathymetric curve and the curve of gradients, the section curve and section curve of gradient along a certain direction, contour section of various indicators and contour section of various indicator gradients, so as to process the data and to represent the figure in 3D. More information, especially the variation information along the longitudinal direction, can be obtained. Gradient prospecting is realized by collecting samples along the depth direction and by analyzing variations in geochemical indicators along the depth.
