摘 要 ：在大兴安岭沼泽硅藻生物多样性的研究过程中,对采自大兴安岭的600余号标本进行了详细的观察,共观察到舟形藻科中国新记录植物10个分类单位,隶属于4个属,其中类缝藻属1种:粗脉肋缝藻;长篦藻属3种:大长篦藻、细尖长篦藻、双型长篦藻;舟形藻属1种:乌普萨拉舟形藻;辐节藻属5种:两头辐节藻、河生辐节藻、细长辐节藻、豆形辐节藻、地中海辐节藻。本文对这些种类的分类学特征及生态分布特点进行了详细的描述。

Abstract:During the investigation of biodiversity of diatoms from Great Xing’an Moutains,more than six hundreds samples were collected and studied.Totally,10 taxa from Naviculaceae were newly recorded in China which belong to four genera.They are:Frustulia crassinervia (Brébisson) Lange-Bertalot & Krammer;Neidium ampliatum (Ehrenberg) Krammer,Neidium apiculatum Reimer,Neidium binodeformis Krammer;Navicula upsaliensis (Grunow) Peragallo;Stauroneis amphicephala Kützing,Stauroneis fluminopsis Van de Vijver & Lange-Bertalot,Stauroneis gracilior Reichardt,Stauroneis leguminiformis Lange-Bertalot & Krammer,Stauroneis mediterranea Lange-Bertalot & Van de Vijver.The detail descriptions of the taxonomical and ecological features of each species are given in this paper.
