淠史杭灌区始建于1958年冬,经过10年的努力,于1968年基本形成淠史杭灌区雏形,形成了一个长藤结瓜式的灌溉网络。灌区建成以来,为改变皖西的贫穷落后面貌,为农业生产的发展发挥了巨大的作用。但由于工程是1958年“大跃进”时的产物,“半拉子”工程较多,所以多少年来,淠史杭灌区是“先天不足,后天失调,带病运行,效益难以充分发挥”。工程上遗留的问题较多,续建配套任务很大,加上淠史杭这样一个庞大的系统工程,跨省、地、县的渠道多,管理上也存在不少问题,灌溉水量、质量都难以保证;渠道上很多建筑物不配套,使得输水、配水无法控制;设计的部分自流灌溉面积
Pishi Shi irrigation area was founded in the winter of 1958, after 10 years of hard work, in 1968 basically formed Pishi Shi irrigation prototype, forming a long vine knot irrigation network. Since the completion of the irrigated area, in order to change the poor and backwardness of West Anhui, it has played a huge role in the development of agricultural production. However, since the project was a product of the Great Leap Forward in 1958 and there were more projects in the “Half-Lazy” project, the Pishihang Irrigation District was “innately inadequate, acquired in the past and run with the disease for many years, making it impossible to give full play to its effectiveness.” There are still many problems left over from the project. The tasks of continued construction are very large. With such a huge system project as Shih-Hang, there are many channels across provinces, prefectures and counties and there are many problems in management. Irrigation water quantity and quality Difficult to guarantee; many buildings on the channel are not complete, making the water, water can not control; part of the design of gravity irrigation area
