【摘要】 黄河上游是黄河流域主要产流区,总体上,水沙特点是水量大,含沙量低,水沙异源,时空分布不均匀。本文根据黄河上游水沙资料,阐述了上游不同区间、流域产沙特性,分析了其变化趋势及其变化原因。更多还原

【Abstract】 The upper reaches of Yellow River basin are main runoff-producing areas. As a whole, the characteristics of runoff and sediment in this area are large runoff with low sediment content, the sources of sediment are different from that of runoff, and uneven in time and spacial distribution of runoff and sediment. Based on the data of runoff and sediment, this paper analyzed the features of sediment-production in different regions of the upper reaches, and their variational trends and causes of variation of sediment.更多还原
