一、灌区简介和存在问题浅析(一)简介淮阴地区水资源的实际利用量约在八十亿立方米左右,其中供灌区用水约占94%左右,基本上保证了农业的高产稳产。但在当前淮阴地区水资源供需还有相当差距的情况下,怎样提高灌区用水的经济效益,达到稳粮增棉、节水节能、促进国民经济的全面发展,是一个非常迫切的课题。淮阴的灌区主要建于1956～1966年,七十年代续建扩大,到七十年代末已建成万亩以上灌区66个,设计控制面积65.7万公顷,有效灌溉面积44.47万公顷由于当时水资
I. Brief Introduction to Irrigation Areas and Existing Problems (I) Introduction The actual utilization of water resources in Huaiyin area is about 8 billion cubic meters, of which about 94% of the water supply for irrigation areas basically guarantees the high and stable agricultural output. However, under the current situation that water supply and demand in Huaiyin area still have a long way to go, how to increase the economic benefits of water use in irrigation areas and achieve steady growth of cotton, water and energy conservation and overall development of the national economy? It is a very urgent issue. The irrigation area in Huaiyin was mainly built in 1956-1966 and continued to expand in the 1970s. By the end of the 1970s, 66 irrigation areas of over 10,000 mu have been built with a designed control area of 657,000 hectares and an effective irrigated area of 444,700 hectares. As the water resources
