摘要： 研究发现,特产于我国东部的南荻TriarrhenalutarioriparaL.Liusp.nov.新种,植株高大,每年秆生长高度达5～7m,年产22.5～30t/hm2干荻秆;秆的纤维细胞含量50%左右(43%～65%),纤维细胞长度平均为3mm,最长可达6.8mm,是制造上等纸张的优质草类原料。芒荻类属于高光效碳四(C4)植物,是有价值的环保植物,在生长过程中,它比一般植物能更多地吸收CO2和放出O2,对平衡大气中的CO2/O2十分有利,并能降低温室效应。研究证明,南荻对环境适应演化的独特机制,能将大面积河湖荒滩湿地改变成为创造经济生态环保效益的生产基地。

Abstract: In taxonomy there is a new species of Miscanthus&Triarrhena denominated in1989,which is an endmic and native grass in China:Triarrhena lutarioriparia L.Liu,sp.nov.The growth rate is5～7meter per year which can produce22.5～30tons of dried-stem per ha per year,being a high biomass plant.As a radical resource,it has been used as a crucial material for paper-making industry.The stems contain50%(43%～65%)of the fibrous cells,with average length each being3mm(2～6.8mm),the maximum,6.8mm.This grass have been proven by scientific approaches as potential crops of C4 -Plants.In Eu-ro pean countries like Germany and England,Miscanthus&Triarrhena is regarded as fuel crops in the future to generate electricity for power stations,i.e.,an important renewable plant re-sources.The research reveals that Miscanthus&Triarrhena is a valuable plant in environmental protection which can balance CO2 /O2 ,reduce soil N2 O and mitigate greenhouse effects in atmo-sphere.

Key words: Triarrhena lutarioriparia L.Liu,sp.nov., biomass, C4 -Plant, energy crops, green-house effects
