如果两个水库都采用修改后的调度图对水资源进行调度（如图4和6所示）。其

If the two reservoirs are used for scheduling view of the modified water scheduling (as shown in FIG. 4 and 6). Its water supply and demand analysis showed that the river water demand can be met, but shipping traffic or can not be fully met. That Nen River, the second Songhua River Songhua all sections and ecological flow Harbin section can be met, but the Harbin section of the shipping traffic can only guarantee rate of 90%.

If both reservoirs use a modified schedule map, the water resources are scheduled (as shown in Figures 4 and 6). The analysis of water supply and demand shows that the water demand of the river can be satisfied, but the shipping flow can not be fully satisfied. That is, the Nenjiang, the second Songhua River section and the Songhua River main stream Harbin section ecological flow can be satisfied, but Harbin section shipping flow guarantee rate can only reach 90%.

If both reservoirs use the modified operation chart to regulate water resources (as shown in Figures 4 and 6). The analysis results of water supply and demand show that the water demand of the river can be met, but the shipping flow can not be fully met. That is to say, the ecological flow of Nenjiang River, the second Songhua River and the main stream of Songhua River in Harbin can be satisfied, but the assurance rate of the shipping flow in Harbin can only reach 90%.<br>
