黄河山东段全长６２８公里，河道的边界条件极为复杂，严重的泥沙淤积使地上“悬河”的情况日趋严重，洪水威胁加大。为增强黄河下游防御洪水的能力，在国家防总、黄河防总的大力支持下，从１９８８年起我省陆续组建了１０支反应迅速、机动性强、能应付各种突发性险情的黄河专 The total length of the Yellow River in Shandong is 628 km. The boundary conditions of the river are extremely complicated. Serious siltation causes the “hanging river” on the ground to worsen and the threat of floods increase. In order to enhance the ability to defend floods in the lower reaches of the Yellow River, under the strong support of the State General Defense and Yellow River Defense Factions, from 1988 onwards, the province has set up 10 Yellow River banks that responded promptly and were highly mobile and able to cope with all kinds of unexpected dangerous situations Specialized
