以综合运行水位控制线、防弃水线、防破坏线、防洪限制水位和死水位作为水库调度指导线，并构成水库调度图,围绕该调度图制定水库综合调度规则，进而建立了调度图模拟-优化模型。选取雅砻江下游梯级水库作为研究对象，采用模拟-优化技术对调度图进行优化。采用优化后的调度图指导水库群模拟运行，模拟运行结果验证了该调度图具有良好的可操作性和实用价值。

The comprehensive control line for the operation water level, anti water discharge line, anti destroy line, the limited water level of flood control and dead water level were used as reservoir operation guide line, and constituted the reservoir operation chart. The simulation and optimization model of operation chart was established according to the comprehensive dispatching rules for the operation chart. Simulation and optimization technology was adopted to optimize the reservoir operation chart, and the optimize method was applied in the lower reach of Yalong River cascade reservoirs. The study showed that the optimization operation chart has good operability and practical value based on guiding the reservoir operation.
