description The invention belongs to the field of detecting oil-gas leakage information by using a remote sensing technology, particularly relates to a method for reflecting carbonate alteration intensity of an oil-gas leakage area by utilizing spectral characteristics. According to the method, it is further determined that carbonation alteration caused by oil and gas leakage is mainly composed of calcite andcontains a small amount of dolomite, the content of carbonation alteration minerals and the change of the symmetry degree of an absorption peak of a reflection spectrum near the wavelength of 2335 nmhave obvious negative correlation, and the carbonation alteration minerals and the depth of the absorption peak have certain positive correlation. According to the method, the content of the carbonate altered minerals can be roughly estimated, geochemical analysis is not needed, the content of the carbonate altered minerals in the oil and gas leakage area can be roughly estimated by utilizing thespectral characteristics o
