A PE waste material-based carbon-fixed aggregate with a wire mesh shell, and a preparation method of the PE waste material-based carbon-fixed aggregate are provided. The preparation method includes the following steps: S1, pretreatment of a PE material collected; S2, carbon fixation for a pumice to produce a carbon-fixed pumice; S3, preparation of a powder-adsorbed pumice; S4, high-temperature calcination to form a wire mesh shell skeleton; and S5, post-treatment. By providing the PE waste material-based carbon-fixed aggregate with the wire mesh shell and the preparation method of the PE waste material-based carbon-fixed aggregate, achieving the comprehensive and effective recycling of waste agricultural mulch films and drip irrigation belts while solving the problems that pervious concrete is susceptible to water erosion and aggregates have poor carbon fixation and sequestration effects.
