芒和荻作为草本能源植物的潜力分析

利用多年生草本植物发展生物质能源产业是可再生能源发展的一个新方向。研究发现，芒和荻是我国本土多年生高大C4草本植物，具有作为能源植物的开发潜力，在欧洲已被广泛应用，在我国仅仅用于水土保持、造纸、饲料等。该文综述了芒和荻的生物学特征、生物质品质特性、生态效益、国内外利用现状，认为该类植物具有生态类型多、野生资源丰富、适应性广，抗逆性强，产量高，净能产出高，生物质品质好，转化利用途径广，生态价值好等特点，是优良的草本能源植物，适合在我国边际土地上种植利用，目前的研究重点应集中于种质资源的搜集、评价和新品种选育及适用于边际土地的栽培管理技术。

The Potential of Miscanthus spp. and Triarrhena spp. as Herbaceous Energy Plants

Using perennial grasses as feedstock for bioenergy industry is a new development direction of renewable energy.Awngrass （Miscanthus spp.） and silverreed （Triarrhena spp.） are C 4 perennial tall grasses and native to China.Being a potential resource of bioenergy plants,they have received considerable attention in Europe but mainly been used for soil and water conservation,paper manufacture,feedstuff and so on in China.This paper reviews the biological characteristics,biomass quality,ecological efficiency,and current research situation at home and abroad,etc.The results show that awngrass and silverreed possess many beneficial attributes being as energy plants because of their diverse ecological types,abundant wild resources,wide adaptability,strong resistance,high net energy output,excellent biomass quality,multiple utilization,good ecological value,and the suitability for marginal lands.Further study should focus on the germplasm collection,evaluation,and selection as well as planting and management techniques for their plantation on marginal lands.
