Intelligent four-quadrant flood regulation method for middle-sized and small-sized reservoirs

The invention relates to an intelligent four-quadrant flood regulation method for middle-sized and small-sized reservoirs. According to the intelligent four-quadrant flood regulation method, the rainfall-runoff relation P+W0-R or W, the peak discharge relation R or W-Qm, the flood regulation relation V-Q, the relation between the total primary flood amount, the rise reservoir capacity and the maximum reservoir water storage W-V-Vm are drawn in a four-quadrant diagram relating to centering; the runoff depth R or the total primary flood amount W corresponding to the precipitation P is obtained according to the peak discharge relation R or W-Qm curve; the Qm corresponding to the runoff depth R or the total primary flood amount W is obtained according to the peak discharge relation R or W-Qm curve; and the Vm corresponding to the runoff depth R or the total primary flood amount W is obtained according to the relation curve between the total primary flood amount, the rise reservoir capacity and the maximum reservo
