摘　　要：The Xihu Lake is Located on the southern Fildes Peninsula. A drill hole is 2. 6 m deep and total 102 samples were collected by Dr. Xie Youyu during 1985-1986. The samples from drill hole in the Xihu Lake contain abundant and well-preserved diatoms and Cysts (Chrysophata), 131 species and variaties of diatoms belonging to 21 genera were recognized. As a result of the detailed research on the diatom assemblages from the Xihu Lake sediments, 9 diatom assemblages were distinguished. From diatom and Cysts (Chrysophyta) data, the changes of the Palaeoenvironments and Palaeoclimate and their age are discussed.The Xihu Lake is Located on the southern Fildes Peninsula.
