The invention provides a complex water network area wedge-shaped water volume computing method. The method comprises the steps of 1, computing the water level elevation, 2, dividing river network grids, 3, computing the projection area and 4, computing the water volume area. The complex water network area wedge-shaped water volume computing method computes the complex river network lake volume based on a plane two-dimensional hydrodynamic model and a water level DEM, a plane two-dimensional hydrodynamic model is built through the network generation technology, relevant parameters are calibrated, verified and determined, the numerical simulation method is adopted to compute the water level elevation distribution in the full lake range under the given lake outlet control water level conditions, the lake water surface DEM data are formed, on this basis, the total lake volume is computed by the adoption of the integral method and combination of the lake water surface DEM data and the lake bed elevation DEM data, and the influences of irregular complex water network lake water curved face on volume computing are effectively avoided.
