摘要:
2001年8月,在新疆维吾尔自治区喀纳斯地区7个样点采集硅藻,经过封片、光镜观察,共鉴定出硅藻有120个分类单位,包括77种42变种1变型,分别隶属于2纲6目10科31属,其中CaloneisholstiiCleve、NaviculasuboccultaHustedt、NCymbellaventricosavar.silesiaca(Bleisch)A.Cleve、Achnantheslanceolatavar.inflataMayer、Epithemiaadnatavar.proboscideaPatr.、Epithemia.intermediaFricke、Hantzschiaamphioxysvar.gracilisGrunow、SurirellaasymmetricaÖstrup、SurirellaengleriΟ;.Müller为中国新记录。对喀纳斯地区硅藻的分布、生态特征也进行了分析。
Abstract:

Of these taxa, Caloneis holstii Cleve, Navicula subocculta Hustedt, Cymbella ventricosa var. silesiaca (Bleisch) A. Cleve, Achnanthes lanceolata var. inflata Mayer, Epithemia adnata var. proboscidea Patr., Epithemia intermedia Fricke, Hantzschia amphioxys var. gracilis Grunow, Surirella asymmetrica Östrup, Surirella engleri Ο. Müller are new records in China. The characteristic of diatoms ecological distribution was discussed.
