Abstract: In recent years，due to the lack of oil resources，the way of using lignocellulose to produce ethanol has attracted more and more attention. Wetland plants were considered as a research object. Using artificial wetland plants to produce fuel ethanol，not only can reduce the gas of harmful emissions，alleviate the lack of grain crops raw materials，but also can reduce the accumulation of wetland plants which could lead to secondary pollution. However，it is extremely difficult to produce ethanol directly from lignocellulose，due to the low rate of ethanol production，the expensive cellulase and the not well developed lignocellulose pretreatment process. This paper is to discuss the stain resistance and decontamination，appropriate allocation and multipurpose use of artificial wetland plants together with the existing problems when wetland plants are chosen. Key process was analyzed regarding the active ingredient of artificial wetland plants and other lignocellulose when fuel ethanol is produced via the pretreatment and hydrolysis effects of artificial wetland plants and other lignocellulose. The feasibility for the preparation of fuel ethanol from artificial wetland plants was discussed，and the future research development trend is prospected. At last，it can be concluded that wetland plants can replace grain crops fermentation to produce ethanol.
