摘要/Abstract

摘要： 泥沙颗粒分析是泥沙研究中的基础工作, 可为河流演变、水生态环境及地质地貌等研究提供基础信息。对当前的泥沙颗粒分析方法进行了分类, 并评价了各种分析方法的优缺点及适用范围, 归纳总结了各种方法的计算原理。应用泥沙颗粒分析工具GRADSTAT对岷江河床采样的泥沙样品进行了计算分析, 结果表明岷江河床质分选很差, 沿程粒径减小, 由于上游水库拦截泥沙作用, 下游的河床质中细颗粒成分较多。

关键词: 泥沙颗粒分析, GRADSTAT, 河床质, 岷江

Abstract: Sediment grain analysis (SGA), as the fundamental work of sediment research, could provide information for river evolution, aquatic ecological environment and geological landforms. In this research, current SGA methods are categorized, the advantages and disadvantages as well as the application scope of each method are assessed, and the calculation principle of each method are summarized. An analysis tool called GRADSTAT is applied to the analysis of bed material sediment samples collected from Minjiang River, and the results show that the sorting of bed material in Minjiang River is inferior, the grain size of sediment decreases along the river, and there are many fine-grained sediments in the downstream bed material because of the interception by upstream reservoirs.

Key words: sediment grain size analysis, GRADSTAT, bed material, Minjiang river
