摘　　要：This note analyzes the change in water renewal time characteristics based on res- ervoir action and then establishes calculation models for the water renewal time in the Yellow River mainstream. The results indicate that the amount of renewable water with reservoir action can meet the annual water demand and that water flows naturally at the Lijin station near estuary. Initial storage dynamics is an important factor in water resource renewable capacity at a certain time, and rational reservoir action can promote sustainable water re- source utilization. When the initial storages in the Longyang Gorge reservoir are 9,343 and 5.343 billion m3, the water renewal times are 28 and 33.9 d, respectively. Flow stoppage appears in April and May.This note analyzes the change in water renewal time characteristics based on res- ervoir action and then establishes calculation models for the water renewal time in the Yellow River mainstream.
