建国四十五年来,全区人民积极投入水利建设,兴建了许多水利工程。一个防洪、排涝、灌溉、供水、航运等综合利用的水利工程体系初步形成。在保障人民生命财产安全、发展工农业生产等方面发挥了重要作用,为国民经济发展提供了有效服务。 解放前,这里水系紊乱,众河串流,洪水肆虐,旱涝频仍,水利设施长期失修,生产力遭到严重破坏,农业生产低而不稳,粮食单产仅50多公斤。新中国成立后,为改变这里水利落后面貌,党和政府十分重视水利建设。建国初期即摆开了治淮战场,对濉河等主要河道结合复堤防洪,进行了水系调整和低标准的疏浚。六十年 In the 45 years since the founding of the People’s Republic of China, the people in the region have actively involved in water conservancy construction and built many water conservancy projects. A flood control, drainage, irrigation, water supply, shipping and other comprehensive utilization of water conservancy project system initially formed. It has played an important role in ensuring the safety of people’s lives and property and in developing industrial and agricultural production and has provided effective services to the development of the national economy. Before the liberation, the water systems were disrupted here, the rivers flowed, the floods raged, frequent droughts and floods, the long-term disrepair of water conservancy facilities, the severe undermining of productive forces, the low and unstable agricultural production, and only a mere 50 kilograms of grain yield per unit. After the founding of new China, in order to change the water backwardness here, the party and government attach great importance to water conservancy construction. In the early days of the founding of the PRC, a battlefield of harnessing Huaihe River was opened and flood control and dike dredging were carried out on the main river courses such as the Yonghe River in combination with the dike embankment for flood control.
