| 中文摘要:非常好的硅藻和金藻组合出现在南极乔冶王岛菲尔德斯半岛西湖全新世沉积物中，共计硅藻有21属，131种和变种。用模糊数学方法对西湖W5、W4、W3、W24个钻孔柱状剖面中硅藻群进行研究，可以划分出10个硅藻组合，显示出硅藻组合的演化趋势和变异特征。研究重点是硅藻群的生活环境特征及其变化，重建古地理环境，提示南极西湖环境与气候的演变规律。 |

| Abstract: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. |
