自1950年治淮以来,我们兴建了淮北大堤、洪泽湖大堤、里运河左堤以及重要城市的圈堤。这些大堤保护了约5000万亩农田和一些重要城市、工厂、矿山、铁路的安全,成绩十分显著。然而在淮河中游岗地之间或岗地与大堤之间存在着一片低洼的河滩地。这些土地解放初期一直是一水一麦,洪水时过水,枯水时种麦,耕作收获是有风险的。治淮初期就规划为行蓄洪区或圩区,进洪机会为2～3年一遇到10～20年一遇。这片土地共计约500万亩,分布在河南、安徽、
Since the establishment of the Huaihe River in 1950, we have built the embankment of Huaibei Embankment, Hongze Lake Embankment, the left canal of the Canal and the important cities. These embankments have protected about 50 million mu of farmland and the safety of some important cities, factories, mines and railways. The achievements have been remarkable. However, there is a low-lying flood land between the middle reaches of the Huai River or between the posts and the levees. In the early days of the liberation of these lands, water and wheat were always available. When the water was flooded and wheat was planted in low water, harvesting was risky. Huaihe initial planning for the flood storage area or polder area, flood opportunities for 2 to 3 years of a 10 to 20 years a case. This piece of land a total of about 5000000 acres, located in Henan, Anhui,
