The present invention discloses an aluminosilicate glass composition, aluminosilicate glass and a preparation method therefor and application thereof. Based on the total molar weight of the aluminosilicate glass composition, the aluminosilicate glass composition comprises, by oxide, 67-74 mol% of SiO2, 10-15 mol% of Al2O3, 0-5 mol% of B2O3, 1-10 mol% of MgO, 1-10 mol% of CaO, 0-3 mol% of SrO, 2-8 mol% of BaO, 0.1-4 mol% of ZnO, 0.1-4 mol% of RE2O3 and less than 0.05 mol% of R2O, wherein RE represents rare earth elements, and R represents alkali metals.
