黑龙江省水资源丰富，且水质较好，泥沙含量小，全省分布的各种引水渠引水条件均较为优越。因而长期以来，对引水渠淤积问题没有引起足够重视和进行有效防治，致使大量引水渠出现程度不同的淤积，引水不畅，严重的渠段被泥沙埋没而报废。因此，有必要对其成因进行分析，进而采 Heilongjiang Province is rich in water resources and has good water quality and small sediment content. All kinds of diversion channels distributed in the province are superior in water diversion conditions. For a long time, siltation of the aqueducts has not been given enough attention and effective prevention and control. As a result, a large number of diversion channels have been silted up to varying degrees, leading to poor water diversion and serious canal sections buried in sediments. Therefore, it is necessary to analyze its causes, and then mining
