安徽淮北地区包括阜阳、宿县两行署,淮北市和淮南、蚌埠两市的淮河以北部分,共22个县市,是安徽省重要的粮食生产基地。耕地面积3253万亩,约占全省耕地面积的一半。建国以来,淮北地区灌溉发展曾几起几落。1958年起,淮北各支流河道大都陆续建起了节制闸蓄水灌溉。淮河干流上修建了蚌埠闸,发展沿淮灌溉。但由于农业上盲目要求大规模稻改,水利上要全面大搞河网化,主观想象要在短期内建立起一个高标准的水网系统,综合解决蓄、引、排、灌、航问题,脱离实际,造成很大损失。七十年代,干旱年份多,淮北面上的水利建设又偏重于抗旱,灌溉费用占水利经费的70％。特别是1978年提出了淮北“三年实现井灌化”的过高要求。1979年夏、秋两次
The Huaibei area of Anhui includes 22 counties and cities north of the Huaihe River in Fuyang and Suxian, two counties in Huaibei and Huainan and Bengbu, and is an important grain production base in Anhui. 3253 acres of arable land, accounting for about half of the province’s arable land. Since the founding of the People’s Republic of China, the irrigation in Huaibei area has experienced ups and downs. Since 1958, most of the tributary rivers in Huaibei have built gate flood control irrigation systems one after another. The Bhubu gate was built on the mainstream of the Huaihe River and irrigated along the Huaihe River. However, due to the blind requirement of large-scale rice reform in agriculture, water conservancy should be comprehensively and vigorously implemented. Subjective imagination should establish a high-standard water network system within a short period of time and comprehensively solve the problems of storage, drainage, drainage, irrigation and navigation, Out of practice, resulting in great losses. Seventies, drought years and more, Huaibei water conservancy construction and emphasis on drought, irrigation costs accounted for 70% of water resources. Especially in 1978, Huaibei put forward the overly high requirement of “well irrigation in three years”. 1979 summer, autumn twice
