摘要

十大孔兑泥沙来源分析对孔兑治理及水土保持生态建设的评价具有重要意义。在十大孔兑中选定西柳沟为代表,采集西柳沟中下游主河槽3份样品及泥沙来源区的沙漠沙与砒砂岩样品,利用QICPIC粒度粒形分析仪分析,提取样品的球形度作为分析指标,通过集对分析的思想分析西柳沟河床质球形度与沙漠沙及砒砂岩球形度的相似性,进而得出沙漠沙与砒砂岩对西柳沟泥沙的相对贡献率。结果表明,来自上游丘陵沟壑区的砒砂岩在入黄口处的含量比中游沙漠区的沙漠沙含量大,洪水更容易将砒砂岩形成的细沙带入黄河。
The analysis on sediment source of ten tributaries has important significance to tributary management and evaluation of water and soil conservation ecological construction. Take Xiliugou River as representative in ten tributaries, three samples in middle and lower reaches of main channel, desert sand and feldspathic sandstone samples in sediment source area were collected. The analysis index of samples sphericity extract by QICPIC. Through analyzing the similarity between bed material sphericity of Xiliugou River and desert sand and feldspathic sandstone by Set Pair Analysis, then get the relative contribution rate of desert sand and feldspathic sandstone to Xiliugou River sediment. The results show that feldspathic sandstone comes from upstream hilly and gully region was more than desert sand comes from middle reaches desert area, the fine sand in feldspathic sandstone get into the Yellow River by flood more easily.
