生物燃料产业、土地占用与粮食安全:综述与拓展

A literature review and outlook on biofuel industry, land acquisition and food security

化石能源短缺、环境污染加剧使得生物燃料已成为世界上增长最快的液体燃料。由于对原料供给的高度依赖,生物燃料产业发展已占用大量土地,对世界和区域粮食安全产生了影响。本文从生物燃料原料选择、对土地占用以及与粮食安全的关系3个方面系统地对国内外研究成果进行梳理评述,最后结合中国国情提出下一步深入研究的方向。

Because of fossil energy crisis and heave air pollution, biofuel ethanol has been the world's fastest- growing liquid fuel. As being highly dependent on raw material, the development of biofuel industry has occupied mass land, and has an impact on world's food security. This paper overall combs the research at home and abroad on biofuel industry from 3 aspects of selection of raw materials, land acquisition, as well as the relation between the industry and food security. Finally it comes to an outlook for in- depth study through reviewing the existing research results.
