淮河干流上中游沿淮两岸的现存圩区、行洪区、蓄洪区,在历史上就是淮河洪水的走廊和滞蓄洪水的天然回旋地区。建国后在五十年代初,遵照“蓄泄兼筹”的原则,为利用洼地有效控制洪水,降低淮干洪水位,确保淮北大堤安全,同时为改善洼地的群众生产生活条件,故把这些洼地按规划意见分别划为圩区,行、蓄洪区,并实行一水一麦政策。经多年实际洪水验证,这些行蓄洪区仍具有扩大行洪能力和滞蓄洪水的双重作用。无论是现在,还是将来,沿淮的行蓄洪区在淮干防洪上都是需要
The existing polders, floodplains and flood storage areas along the upper and middle reaches of the Huaihe River along the Huaihe River are historically the corridor of the Huaihe River flood and the natural maneuvering area that floods flood waters. After the founding of the People’s Republic of China in the early 1950s, in accordance with the principle of “storing both the reservoir and the reservoir,” it was proposed that in order to utilize the depression to effectively control the flood, reduce the flood level of the Huai River, ensure the safety of the embankment in Huaibei and improve the production and living conditions of the masses in the depression, According to the planning opinions are divided into polders, lines, flood storage areas, and the implementation of a water-wheat policy. After years of actual flood verification, these flood storage areas still have the dual role of expanding flood discharge capacity and flood storage. Whether it is now or in the future, the flood storage area along the Huaihe River is needed for flood control in the Huaihe River
