利用洪水泥沙资源的重要意义发展西北地区农业生产、治理黄河的根本问题,在于解决黄河中游黄土高原区和丘陵沟壑区的水土流失问题。据黄河四十二年水文资料的统计分析,每年平均总水量四百三十六亿立方米;汛期七、八、九、十四个月的洪水量占百分之六十,泥沙量占年平均十七亿吨的百分之八十四。有些年份洪水沙量更集中,如北洛河一九五九年输
Making use of the significance of flood and sediment resources to develop agricultural production and harness the Yellow River in the northwest region is to solve the problems of soil and water loss in the loess plateau and hilly areas in the middle reaches of the Yellow River. According to the statistical analysis of the hydrological data of the Yellow River for 42 years, the average annual total amount of water is 43.6 billion cubic meters; floods in flood seasons account for 60% of the flood volume in the seventh, eighth, ninth and fourteen months, and the amount of sediment An average of 84% of the 1.7 billion tons per year. In some years, the amount of floodwater is more concentrated, such as the loss of North River in 1959
