Gas consumption prediction method and system based on big data analysis

The invention relates to the technical field of gas prediction, and provides a gas consumption prediction method and system based on big data analysis, and the method comprises the steps: collecting the gas consumption data of all users at a plurality of sampling moments; performing data processing by using a big data processing platform to obtain a gas consumption prediction result, specifically, obtaining a gas consumption sequence of an original user and a new user; constructing a meso-position gas consumption sequence, determining a representative user sequence of representative users, obtaining representative volatility of the representative users in combination with the difference between the meso-position gas consumption sequence and the representative user sequence, and obtaining fluctuation factor characteristic values of the gas company in combination with the number of newly-added users; and determining a smoothing coefficient value according to the fluctuation factor characteristic value of the ga
