洪水灾害是我国主要自然灾害之一,就淮河流域来说水患更为严重。建国后,国家在淮河流域修建起5300多座水库,总蓄水量达250亿立方米,建起水闸4000多座,开辟了18个行洪区、4个蓄洪区,兴修堤防2697公里,新开入海河道3条,入长江水道1条,行洪能力从过去的8000立方米每秒提高到24000立方米每秒。所有这些水利设施,基本改变了解放前每遇大水即大面积决口泛滥的局面,防洪方面的成绩是非常显著的。但是,由于洪水具有峰高量大、突发性强等特点,目
Flood disasters are one of the major natural disasters in our country, and the floods are even more serious in the Huaihe River Basin. After the founding of the People’s Republic of China, the state built more than 5,300 reservoirs in the Huaihe River Basin, with a total storage capacity of 25 billion cubic meters and more than 4,000 sluices built. It has opened up 18 flood discharge areas, 4 flood storage areas and built 2697 km of embankments. Opened into the Haihe River 3, into the Yangtze River waterway 1, flood capacity increased from 8,000 cubic meters per second to 24,000 cubic meters per second. All of these water conservancy facilities have basically changed the situation of large-scale flood surges that occur every time before the liberation. Flood control achievements are remarkable. However, due to floods with high peak volume, sudden strong features
