Method and device for calculating annual average silt loss rate of reservoir, electronic equipment and storage medium

The invention discloses a method and device for calculating the annual average silt loss rate of a reservoir, electronic equipment and a storage medium. The method comprises the steps: acquiring sedimentation data of a plurality of reservoirs in N target drainage basins, wherein the N target drainage basins are located in a target area; calculating the annual average siltation loss rate of each reservoir according to the siltation data of each reservoir; based on the siltation loss rate of each reservoir and the reservoir capacity data corresponding to each reservoir, calculating a reservoir annual average siltation loss rate of each target drainage basin by adopting a weighted average algorithm; determining the actual total reservoir capacity of each target drainage basin based on the reservoir capacity data of each reservoir in each target drainage basin; and according to the reservoir annual average silt loss rate of each target drainage basin and the actual total reservoir capacity of each target drainage
