With the advent of the era of big data，the continuous development and maturity of cloud computing，big data and artificial intelligence technology provide a new powerful starting point for the supply side reform in the field of science popularization. In the era of big data，the supply and demand of science popularization have changed profoundly，which has a huge impact on traditional science popularization. Therefore，it is imperative to reform the supply side of traditional science popularization by using the increasingly mature new technology to carry out the new mode of “intelligent plus” science popularization. This paper first analyzes the feasibility and challenges of “intelligent plus” science popularization from the perspective of technology，then introduces Beijing’s advanced practice in “intelligent plus Science Popularization”，and summarizes it as the Beijing supply mode of “intelligent plus” science popularization of “point，line and surface”，finally，from the establishment of science popularization information platform，the technical analysis of science popularization demand and the enhancement of science popularization personnel’s learning of new technology Some suggestions are put forward.
