对大兴安岭曲壳类硅藻进行了分类学研究,结合国际通用的分类系统对KarayeviaRound & Bukhti-yarova(卡氏藻属)、LemnicolaRound & Basson(附萍藻属)、PlanothidiumRound & Bukhtiyarova(平面藻属)和Psammothidium Bukhtiyarova & Round(沙生藻属) 4个属的分类特征进行了描述,对在大兴安岭地区观察到的曲壳类硅藻 12 个分类单位进行了详细的形态学描述, 并给出了他们的生境分布特点.研究观察到中国新记录3个分类单位:Achnanthes tumescens Sherwood & Lowe (膨胀曲壳藻)、Planothidium lanceolatoide (Sovereign) Lange-Bertalot(近披针形平面藻)、Psammothidium rossii(Hustedt) Bukhtiyarova & Round(罗斯沙生藻).

In this project we studied Achnanthoid diatoms collected from the Great Xing'an Mountains. The morphological features ofKarayeviaRound & Bukhtiyarova,LemnicolaRound & Basson,PlanothidiumRound & Bukhtiyarova,Psammothidium Bukhtiyarova & Round were described in the Chinese language. The morphological characteristics and the distribution pattern of twelve achnanthoid taxa from the Great Xing'an Mountains were described in this study. Furthermore, here we reported three taxa as the newly recorded species in China, which were Achnanthes tumescens Sherwood & Lowe,Planothidium lanceolatoide (Sovereign) Lange-Bertalot, andPsammothidium rossii (Hustedt) Bukhtiyarova & Round.
