A method for combined characterization of pore structure includes steps as follows. Firstly, CO, Nand high-pressure mercury intrusion porosimetry characterization curves are plotted based on actual measurement data, then, average values of the overlapping range of the COand Ncharacterization curves are calculated, and a function y'=ƒ(x) is fitted. Each pore volume y′ corresponding to each pore diameter xis calculated, and a curve is plotted with xas a horizontal coordinate and y′ as a vertical coordinate, thereby obtaining a characterization curve of the overlapping range between COand Nadsorptions. The same data processing is used to process the overlapping range data of the Nand high-pressure mercury intrusion porosimetry characterization curves, to obtain the characterization curve between them. The characterization curves are spliced with the original CO, N, and high-pressure mercury intrusion porosimetry characterization curves to obtain a combined characterization curve.
