%X 2008年编制的黄河流域防洪规划，对于近十多年保障黄河防洪安全发挥了重要作用。但由于规划所选择的设计水沙系列，未充分考虑水土保持工作改善流域下垫面，使从黄土高原进入黄河的水、特别是泥沙显著减少的现象。因而计算的小浪底水库淤积和下游河道冲淤变化，均与实际出现的情况相差甚远。我国已进入绿色发展的新时代，随着生态修复的进展，入黄泥沙减少的趋势是不可逆转的。因而，必须对早期观测的水沙资料，按下垫面的变化进行修正，修正后的水沙资料，才能作为预测未来水沙条件的依据。才能使预测的水沙条件接近未来的实际情况，才能做出最优的治理方案。按下垫面的变化修正水沙资料的理念，不单适用于黄河，对一切下垫面发生较大变化河流都适用。<br />
The Yellow River Basin Flood Control Planning compiled in 2008 has played an important role in en-suring the flood control safety of the Yellow River in the past ten years. However, the design water and sediment series selected in the planning, have not fully considered the phenomenon that the water and soil conservation works improved the basin’s underlying surfaces, and significantly reduced the water, especially sediment, entering the Yellow River from the Loess Plateau. Therefore, the calculated changes of the Xiaolangdi Reservoir siltation and the downstream channel scouring and silting are far from the actual situation. China has entered a new era of green development. With the progress of ecological restoration, reduction trend of sediment into Yellow River cannot be reversed. Therefore, it is necessary to correct the water and sediment data observed in the early stage according to the change of the underlying surface. The corrected water and sediment data can be used as the basis for predicting the future water and sediment conditions. Only in this way the predicted water and sediment conditions can be close to the actual situation in the future, and the optimal management program can be made. The concept of correcting water and sediment data according to the change of the underlying surface is applicable to not only the Yellow River, but also all the rivers with great changes in underlying surfaces.
