When two reservoirs are in abundant or flat water, the reservoir can be used alone to meet the needs of downstream water resources. In this case, there is no need to carry out the joint use of reservoir dispatch.

When the two reservoirs are in high water or flat water, the reservoir can meet the downstream water demand by using alone. In this case, it is not necessary to carry out joint reservoir operation. The joint use of the reservoir has little effect: Fengfeng, Fengping, Pingfeng, Pingping, the frequency is 40.92%.<br>
