80年代黄河来水来沙偏枯。但下游引水却逐年增加,年引水量约占河道来水量的1/4;引沙量随来沙量的丰枯而变化,约为2.6～1.0亿t。从历年引水引沙过程分析,高村以上的河南河段引水基本稳定略呈下降趋势,高村以下的山东河段则呈阶梯状稳步上升。这种不平衡的用水状况有待调整。 The Yellow River in the 1980s came to sand partial dry. However, the diversion of water from the lower reaches has been increasing year by year, and the annual water diversion accounts for about 1/4 of that of the rivers. The amount of sediment introduced varies with the abundance of sediment, which is about 2.6-1.0 billion tons. Based on the analysis of the process of diversion and sediment from the previous years, the water diversion basically showed a slight downward trend in the Henan reach above Gao Village, while the Shandong reach below the high village rose steadily. This imbalance of water conditions to be adjusted.
