The application discloses an alite-belite composite new-phase high-strength cement clinker and a preparation method thereof. In terms of mass percentage, a mineral phase composition of the cement clinker comprises C3S: 15-25%, C2S: 30-40%, Q phase: 15-25%, C4A3$: 10-20% and C4AF: 5-10%. The Q phase is a CaO-Al2O3-MgO-SiO2 quaternary compound, and the C2S contains alpha'-C2S. A modifier is further added to a raw material composition of the cement clinker, and the modifier simultaneously comprises a metal oxide and a non-metal substance. The process of the application successfully realizes coexistence of a high-temperature mineral phase (tricalcium silicate) and a low-temperature mineral phase (calcium sulphoaluminate and Q phase) in the cement clinker, simultaneously converts dicalcium silicate from a low-activity form into a high-activity form, and overcomes the problem of insufficient strength development in a middle and later period of a high-belite sulphoaluminate cement.
