Parameter distinguishing scene intelligent calibration hydrological forecasting method and terminal

The invention discloses a parameter distinguishing scene intelligent calibration hydrological forecasting method and terminal, and the method comprises the steps: S0, building a production and confluence calculation basic database containing historical rainfall data, and building a parameter scheme database which correspondingly divides different rainfall scenes according to expert experience; s2, acquiring forecast rainfall data, performing classification according to the forecast rainfall data, selecting corresponding scene model parameters from the parameter scheme library according to a classification result, performing flood forecast by using a hydrological model, and storing the rainfall data and the corresponding hydrological data into a runoff calculation basic database according to the classification result after flood; and S3, if a set calibration condition is met, allowing the user to calibrate the parameters, and if a calibration parameter instruction input by the user is obtained, performing inte
