| Evolution of the Holocene Diatom in the Fildes Peninsula,Antarctic——Study by Fuzzy Cluster Analysis |
| Profuse and well-preserved assemblages of diatoms and cysts(chrysophyta)occur in the majority of samples from the Holocene deposits, subsurface sequence of the Xihu Lake well in fildes Peninsula of King George Islands, Antarctica. There are twenty-one genera, one hundred and thirty one species and variaties. The purpose of theis paper is to discuss the evolution trend and variations of the diatoms,using a method of fuzzy cluster analysis this comprehensive study of the diatom assemblages graphically. All of the problems in geology are characterized some fuzzy ,thus the classification processsing by means of the methods on fuzzy mathematics can even more effect. |
