Isograms of sediment transportation modulus and coarse sediment modulus are drawn up based on the obtained data.The variation law of sediment and coarse sediment transportation modulus at areas with more and coarse s...             该文根据绘制的黄河中游输沙模数与粗泥沙模数等值线图，研究分析了黄河中游多沙粗沙区输沙模数与粗沙模数变化规律。 文摘来源          There were two ways, distribution graphs of sediment yield and muddy and coarse sediment modulus index, applied for determining the key harnessing regions of soil and water loss in the Yellow River basin, both of them needed coarse sediment data. There have been limited accuracy of the ways because there are less stations with sediment particle-size analysis data. The way applied in the paper is determining the key harnessing areas on sediment charge distribut...             过去确定黄河流域水土流失重点治理区主要采用来沙分配图法和多沙粗沙模数指标法,这两种万法都需用到粗泥沙资料,由于有泥沙颗分资料的测站较少,故其精度有限.根据河龙区间7～8月份水流平均含沙量300kg/m~3的指标,在含沙量分布图上确定出重点治理区,该万法只涉及全沙资料,而有全沙资料的站网控制密度相对比有粗泥沙资料的站网控制密度耍大得多,因此其精度也就高得多.黄河流域重点治理区为11.3万km~2,其中河龙区间为5.7万km~2,泾洛渭河为3.2万km~2,祖厉河、苦水河为2.4万km~2,河龙区间的5.7万km~2是重点中的重点. 文摘来源          Through the analysis of grain-size sampling of sediment deposition which from many sections,holes and deep layers in Lower Yellow River,we concluded that sediment deposition grain-size larger than 0.1mm in the main channel occupies 50% before 1960,in which year Sanmenxia reservoir operated.The centralized source area of coarse sediment is 18.8 thousand km~2,according to 2 indexes,one is grain-size larger than 0.1mm,the other is coarse sediment modulus equal to 1400 ...             通过黄河下游多断面、多钻孔、深层次泥沙淤积物取样级配分析,认为在1960年三门峡水库运行前,下游河道主槽淤积物中0.1 mm以上泥沙占一半。以0.1 mm为粗泥沙集中来源区界定研究中的粗泥沙界限,0.1 mm的粗泥沙输沙模数1 400 t/(km2.a)为粗泥沙集中来源区界定指标,界定出黄河中游粗泥沙集中来源区面积为1.88万km2。该区面积仅占黄河中游多沙粗沙区面积(7.86万km2)的23.9%,但该区产生的全沙量、d≥0.05 mm和0.1mm的粗泥沙量分别占多沙粗沙区相应输沙量的34.5%,47.6%和68.5%,说明该区是名符其实的产粗泥沙“大户”,是当前黄河粗泥沙“源头”治理的重中之重。 文摘来源       相关查询: coarse sediment sediment modulus modulus of coarse sediment transportation coarse grained sediment sediment yield modulus graded coarse sediment modulus of sediment sediment transportation modulus coarse suspended sediment coarse sediment region sediment transport modulus modulus of sediment transportation  对查询结果不满意
