Analysis on the strategy development of sugarcane fuel ethanol in China

Sugarcane and cassav a are tropical、subtropical plants,which have a good suitability to marginal land such as alluvion、hillside and saline-analkaline land,and widely cultivated in main sug-arcane producing area: Guangxi,Yunnan,Guangdong and Hainan province.Cassava fuel ethanol faced the problems that the yield of cassava was not sufficient for producing and price rising.The advantages of sugarcane as the raw material of fuel ethanol over cassava were analyzed in this paper.The long term demand of sugar and it's surport potential capacity of land in China were studied at the same time.Compared to cassava,sugarcane had several advantages over cassava,which had a high yield ethanol per unit of land,high comprehensive utilization value,a better effective energy saving and reducing carbon dioxide emissions,while be beneficial for environmental protection and price stabilization.It showed that through intercropping technology that one million tons sugarcane fuel ethanol can be produced in near-term future and two-three millions forward by the guarantee of food、sugar security and sugar price reasonable.
