Method and system for constructing incoming water forecasting model of typical karst landform drainage basin

The invention discloses a construction method and system of a typical karst landform drainage basin incoming water forecasting model, and relates to the technical field of prediction model construction, and the method comprises the steps: carrying out the downscaling research of meteorological historical data based on the existing meteorological observation data; on the basis of typical hydrological section observation data, runoff data of a sub-basin outlet section are calculated, and a linear regression equation of the sub-basin runoff is established by utilizing the sub-basin surface rainfall and runoff and utilizing a least square method; and constructing a day-by-day short-term and hour-by-hour short-term and temporary incoming water forecasting model of the small reservoir in the typical karst landform area by using a deep learning algorithm, and carrying out model and parameter optimization. Through existing meteorological observation data and hydrological section observation data, downscaling research
