黄河中游严重水土流失区土壤粒径分布规律研究
Study of Distribution Law of Soil Particle Diameter in Serious Soil and Water Loss Zone of the Middle Reaches of the Yellow River
【摘要】 通过野外考察和室内分析计算,在利用水文站实测悬移质颗粒级配组成和淤地坝取样资料分析的基础上,探讨总结了研究区粗颗粒泥沙、平均粒径以及中数粒径的变化规律,提出了黄河中游严重水土流失区土壤粒径由南向北颗粒逐渐变粗的趋势。
【Abstract】 By the field surveying and indoor analyzing calculation,based on using observed suspended-load grain composition in hydrological station and analyzing datum of sample in alluvial dam,variational law of coarse sand,average grain diameter and median particle diameter in the test area is discussed and summarized,it is brought forward that the trend of soil of particle diameter becoming big from south to north in serious soil and water loss zone of the middle reaches of the Yellow River.
