本文分析了来自退化土地（LIHD）上低投入高多样性草地生物质的负碳生物燃料的能源利用，包括相当于温室气体（GHG）捕获和储存的能源。结果表明，退化土壤上LIHD生物质的能量输出几乎等于肥沃土壤上传统玉米粒产生的乙醇。研究还表明，LIHD 生物燃料比玉米乙醇或大豆生物柴油等传统生物燃料经济得多。中国是一个发展中农业大国，农村人口众多，土地退化严重。正是在这方面，我们分析了 LIHD 的利用。估算了中国退化土地上利用 LIHD 生物质产生的能源的潜力。结果表明，LIHD生物质的潜在能源产量达到6350971.32TJyear−1，约占2002年中国能源消费的15%。
This paper analyzes utilization of carbon-negative biofuels from low-input high-diversity grassland biomass on degraded lands (LIHD) for energy including energy equivalent to green house gases (GHG) capture and storage. The results show that the energy output of LIHD biomass on degraded soil is nearly equal to that of ethanol from conventional corn grain on fertile soil. It has also been shown that LIHD biofuel is far more economical than the conventional biofuels such as corn ethanol or soybean biodiesel. China is a large agriculturally developing country, with its rural area largely populated and vast land degraded. It is in this respect that we analyzed the utilization of LIHD. The potential of using energy from LIHD biomass on degraded lands in China is estimated. The results show that the potential energy production of LIHD biomass reaches 6350971.32TJyear−1, accounting for about 15% of China’s energy consumption in 2002.
