摘要:
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。

CORRESPONDENCE ANALYSIS OF SIZE-ANALYSISDATA FROM CORE Ch5, CHANGJIANGRIVER DELTA
Abstract:
Size-analysis data of 30 sediment samples collected from core Ch 5 Changjiang River Delta were statistically analysed by means of correspondence analysis method. Result of the analysis shows: there are three types of hydrodynamic deposit environments through core Ch5, which are similar to those delineated by using transitional size-analysis method. This paper also suggests that correspondence analysis is a better multivariate analysis for size analysis.
