摘　　要：为促进中国边际土地草本能源植物种植与生物质原料生产,基于京郊边际土地草本能源植物规模化种植的实践,从生产潜力、生物质品质、生物质利用潜力、生态效应等4个方面对荻的应用潜力进行了分析评价。结果表明:荻在京郊挖沙废弃地上的生产潜力为2.31t/hm2,达到京郊耕地条件下的8.41%,生物质品质优良,其标准煤折算当量、沼气产量、纤维素乙醇产量分别为1.42t/hm2、289.99m3/hm2、0.59t/hm2,分别达到京郊耕地条件下的8.38%、8.37%、8.15%,生态效应明显。荻在边际土地上具备良好的应用潜力。For the promotion of cultivation of herbaceous bioenergy plant and production of biomass feedstock on marginal land in China, the evaluation of application potential oi silver reed was conducted, including the analysis of production potential, biomass quality, biomass utilization potential and ecological effects, based on the practical activies of the large-scale cultivation of herbaceous bioenergy plant on marginal land in Beijing suburb. The results showed that the production potential of silver reed was 2.31 t · hm 2 on abandoned sandpits in Beijing suburb, accounting for 8.41% of that on arable land in Beijing suburb. With good biomass quality and ecological effect, its standard coal equivalent,biogas and cellulosic ethanol yield were 1.42 t ·hm-2 ,289.99 m3 · hm-2 ,0.59 t ·hm-2, respectively, accounting for 8.38% ,8.37% ,8. 15% of that on arable land in Beijing suburb. Silver reed has a great application potential on marginal land in the future.
