Abstract: The present disclosure discloses a method and system for calculating a carbon and water flux of an ecosystem based on a weather station, and relates to the technical field of calculation of carbon and water fluxes of ecosystems. According to a plant function type (PFT) and/or a climate type, eddy covariance flux stations are selectively combined to obtain a plurality of combinations characterizing different scenarios of an ecosystem and a plurality of carbon and water flux data sets respectively corresponding to the plurality of combinations, a plurality of carbon and water flux models and an evaluation model for predicting a determination coefficient are further constructed, and the evaluation model is used to determine a carbon and water flux model suitable for each weather station in a target area, such as to calculate a carbon and water flux based on observation data of the weather station.
