The invention belongs to the field of the organic-inorganic hybridized silicon film material preparation, and particularly relates to an organic-inorganic hybridized silicon film hole structure and a modification method for surface property. The method comprises the following steps: executing the epoxidation and open-cycle sulfonation reaction to an olefin group in an organic-inorganic hybridized silicon film by using tert-butyl hydroperoxide solution and NaHSO3/Na2SO3 solution, and enabling the aqueous affinity of the film to be improved greatly, and increasing the water permeability.
