摘要
选择土地集约型的非粮作物发展生物燃料对土地资源极度稀缺的我国而言尤为必要。基于此,本文首先通过综合比较优势指数法分析了我国不同地区发展生物燃料乙醇的非粮作物选择,结果显示,未来我国发展生物燃料乙醇的能源作物主要来自甜高粱和甘薯。其次,根据边际土地的可获得性和能源作物的产量评估了我国生物燃料乙醇的潜力和结构,认为边际土地的利用率只要达到40%就可实现我国可再生能源中长期发展规划目标。最后,根据相关的结论对我国生物燃料发展提出了一些政策建议。
Due to extremely scarce land resources,it is necessary for China to develop biofuel by growing nongrain crops instead of grain crops on the marginal land. Based on this,the paper first assesses developing nongrain crop in different regions with comprehensive comparative advantage index. The result shows that crops for developing biofuel in China,ethanol in specific,are mainly sweet sorghum and sweet potato. Then it assesses the potential and yield structure of China' s bioethanol development based on marginal land availability and energy crop yield. The result shows that if marginal land utilization rate reaches 40%,China's mid and long term target of developing renewable energy can be realized. Finally some policy suggestions are make according to the conclusion.
