摘要
湖南中部长沙、宁乡、益阳、安化、涟源、邵东等县，中泥盆统跳马涧组和棋子桥组产丰富的轮藻化石，以宁乡县崔坪峡塘剖面为代表，有3属7种1型1新种，并首次发现了轮藻植物节部化石。建立了2个化石带：（1）Trochiliscus ingricus-Eochara changshaensis组合带，分布在跳马涧组，时代为中泥盆世早期；（2）Sycidium顶峰带，分布在棋子桥组，时代为中泥盆世晚期，并对轮藻的生活环境进行了探讨。
The Tiaomajian and Qizhiqiao formation of middle Devonian system occur abundant charophyte fossils in the middle counties of Hunan , including Changsha. Ningxiang. Yiyang. Anhua. Lianyuan. Shaodong, etc. Cuipingxiatang section, in Ningxiang County, is the typical section, and its charophyte fossils are classified into 3 genus.7 species. 7types including a new type. The author build 2 belts fossils and discusses the living environment of charophytes: 1) Trochiliscus ingricus-Eochara changshaeesis belt; It distributes in Tiaomajian formation of middle Devonian period. 2) Sycidium summit belt; It distributes in Qizhiqiao formation of middle Devonian period.
