摘要
该文主要根据现场采集的 12 6个沉积物样品的粒度分析资料 ,运用对应分析和C -M图等方法 ,结合地貌和水动力条件 ,划分出三种不同类型的动力沉积环境 ,即潮流沉积环境、潮流波浪混合沉环境和波浪沉积环境 ,并进一步探讨各沉积环境的动力沉积机制。
This paper, based on lots of field data and the predecessor's achievements as well as the grain size values of the bottom materials which come from 126 samples almost covering the whole research district, applying the multielement analysis-correspondence analysis and C-M diagram, etc, distributes the research district into three types of sediment environment, the tide deposition, the tide-wave mixed deposition and the wave deposition environments. Furthermore, the paper analyzes the sediment mechanism in each sedimentary environment.
