The invention relates to a preparation method of sol-gel uv/thermal cross-linking of a hybrid anion exchange membrane, and is characterized in that: sol-gel reaction is carried out with radical alkoxy silane that contains uv or thermal cross-linking in a molecule chain and positively charged alkoxy silane, or with other alkoxy silanes and/or organic monomers, then the uv cross-linking or the thermal cross-linking is carried out, or the uv cross-linking is first carried out, then the thermal cross-linking, so as to obtain an organic-inorganic hybrid anion exchange membrane. The step of thermaland/or uv cross-linking adopted in the preparation process can form an organic polymer network so as to get the hybrid membrane with better flexibility; inorganic oxide components and organic components in the hybrid membrane can connect with each other by chemical bonds, so as to realize better compatibility; the components of the raw material of the invention method can be adjusted easily with high ion exchange capacity
