| 摘要: |
| 当前社会不允许错失生物质能源减排温室气体和促进地区能源、环境与社会发展天赐良机，也不能接受其对粮食安全、生态环境和社会发展的任何不良影响。本研究在总结能源植物土地利用坚持非粮和生态保护原则的基础上，首先分析了我国当前土地利用与保障粮食安全的关系，认为大量土地撂荒、闲置和污染表明能源植物生产用地前景广阔。其次论证了我国应确立“以粮为纲、粮能并举”的土地利用方针，优化土地管理，实现土地集约利用，走保障粮食安全、发展能源和保护生态的多赢路线。最后确定了适宜于中国国情的可用于种植能源植物土地（宜能非粮地）的定义，讨论了宜能非粮地的污染超标、撂荒闲置、低等级、未利用、多用途增值和自然系统等非粮特征，将其分为宜能非粮耕地、宜能园地、宜能林地、宜能荒草地、宜能交通运输绿化用地、宜能水域和水利设施用地和其他未利用宜能土地等7大类。据此建议进一步研究土地利用的非粮和宜能的相关具体指标，以确定宜能非粮地的分级、面积和分布。 |

| Abstract: |
| In a world seeking solutions to its energy,environmental,and food challenges,we cannot afford to miss out on the global greenhouse-gas emission reductions and the local environmental and societal benefits when biofuel are appropriately manipulated.On the other hand,undesirable impacts due to abuse of biofuel on food security,environment,and society were also unacceptable.Based on ensuring food security and protecting environment principles,the paper firstly clarified the relationship between land use and food security in China,indicating a great quantity of abandoned agricultural land and polluted land that is not suitable for food production,but potentially suitable for energy plant production.Secondly,the study suggested a win-win path to optimize and intensify land use for food and energy production,in order to improve food security,developing biomass energy,and protecting environment synchronously in the country.Thirdly,the non-food land suitable for energy plant production (LSEP) was defined properly after a discussion on the characteristics of polluted land,abandoned agricultural land,unused land,and etc.according to the national situation.The NLSEP was classified into non-grain cultivated land for energy plant production (NC-LSEP),orchard land suitable for energy plant production (O-LSEP),forest land suitable for energy plant production (F-LSEP),waste grass land suitable for energy plant production (WG-LSEP),transportation and virescence land suitable for energy plant production (TV-LSEP),water area and facility land suitable for energy plant production (WAF-LSEP),and the other unused land suitable for energy plant production (OU-LSEP).Finally,the authors suggested further studies on the criteria of non-food and suitability for energy plant production in order to identify NLSEP area and distribution. |
