本文对长江三角洲Ch5孔30个沉积物样品的粒度资料进行了对应分析。结果表明,该孔沉积物的成因类型主要有3种,与传统的粒度资料分析结果相吻合。研究结果还表明,对应分析在粒度资料中的应用效果较佳。
In this paper, the grain size data of 30 sediment samples from Ch5 pore in the Yangtze River Delta are analyzed. The results show that there are mainly three types of genetic types of sediments in this hole, which are consistent with the results of traditional particle size data analysis. The research also shows that the application of correspondence analysis in granular data is better.
