东明县位于山东省西南部,地处豫鲁之交,黄河在东明境内全长66.00km,共有引黄闸4座,设计灌溉引水能力175m~3/s,年最大引水量已超过10亿m~3,引黄灌溉有着得天独厚的优势。但大量引水造成河渠严重淤积,制约了灌溉效益的充分发挥,大大降低了防洪抗灾能力。 Dongming County is located in the southwest of Shandong Province, located in the intersection of Henan and Shandong, the Yellow River in Dongming territory of a total length of 66.00km, a total of four yellowing gates, design irrigation diversion capacity of 175m ~ 3 / s, the maximum annual water diversion has more than 1 billion m ~ 3, the Yellow River irrigation has a unique advantage. However, a large number of diversion led to serious siltation of the canal, which restricted the full benefit of irrigation and greatly reduced the ability of flood control and disaster relief.
