摘要
It is difficult to further study the ancient-environment influenced by different sources and deposit dynamics by sediment grain properties of total samples.Multicomponent separation methods of different sediment grain were widely discussed in recent years,but only single method was used and there was no comparative analysis of different methods.Environmental sensitive factors by grade-standard deviation method and factor analysis method and their ancient-environment significance were compared based on three column sediment grain properties in Sishili Bay,Yantai.The result shows that sensitive grade based on the two methods one-to-one correspond and has the same variation tendency in column sediment,which indicates the two analysis methods can sensitively denote the same deposit dynamics.But the sensitive factors by grade-standard deviation are affected by end member,and only main control environmental significance is inverted.
