丹江口水库作为南水北调中线工程的源水库,延长其使用寿命、保证其长久良好地运行,不但有重要的经济意义,而且有更重要的社会意义。排沙清淤是保证丹江口水库能长期运用良好的重要措施。根据丹江口水库的自身特性,在变动回水区及其附近进行“防治型”排沙清淤是治理库区淤积泥沙的有效途径,与传统的坝前“治疗型”排沙清淤相比有许多优越之处。
Danjiangkou Reservoir, as the source reservoir of the Middle Route Project of South-to-North Water Diversion, extends its service life and ensures its long-term good operation, which not only has important economic significance but also has more important social significance.
