摘要
长白山是著名的巨型复式火山,位于我国吉林省东部,火山锥顶的火口积水成湖,名曰天池。天池湖水北下入通天河,后至二道白河。通天河急流形成瀑布,瀑布东北有大片温泉,西有常年滴水的石壁。此地区的硅藻前人尚未研究,经本文研究,计有硅藻264分类单位,分别隶属于34属,其中包括1新变种、2新变型和1新组合。通过此项研究,阐明该地区的硅藻区系和生态分布特点,提供研究长白山地区硅藻的新资料。
Changbaishan Mountain is a volcano located in the eastern part of Asia between China and Korea.The lake formed from this volcanic action is called Tianchi Lake which is situated on the summit.Outflow of water from the lake forms the Tongtian River which then enters the ErdobaiRiver a short distance downstream.Collection sites throughout this area included riot only the lake and the rivers,but also a few selected sites in the valley floor on either side of the water course.Such habitats as a waterfall,moist rocks,hot springs and moist forest floor were sampled for diatoms. On September 9th and 10th,1983,17 diatom collections were made at nine localities.This is the first investigation of diatoms in this area.Two hundred sixty four taxa are reported representing 34 genera,including 2 new varieties,1 new form,and one new varietal combination.
