(57) A low-carbon cement clinker and a preparation method therefor, The low-carbon cement clinker comprises the following rate value ranges: the alkalinity coefficient. C: 1.0 < C < 1.5; the aluminum-sulfur ratio P: P<1.92; the aluminum-silicon ratio N<1: and the lime saturation factor Cs: 0.9 < Cs<1.0. The lime saturation factor Cs is obtained by means of correcting the alkalinity coefficient C while taking into account the content of SO₃ component. The present invention comprises setting an oxide composition of the low-carbon cement clinker according to C, P, N and Cs; or according to C, P, N and Cs, first setting specific rate value parameters, then reversely calculating the oxide composition, and according to the oxide composition and the oxide contents of various raw materials. deducing and calculating the ratio of the various raw materials.
