| 摘要: |
| 就近年来中国不影响粮食安全的适宜发展能源植物生产的土地资源的研究成果进行综合述评。分析相关的概念定义,确定宜能非粮地或宜能边际地作为同义词是最合适的术语,其定义为经济上或生态上不适宜生产粮食,但具备能源植物生长需要的基本条件,适宜于规模化种植或天然生长非粮能源植物的土地。讨论并确定宜能非粮地包含的土地种类,即不适于粮食作物和果树的耕地和园地、宜能林地、荒草地、可复垦工矿废弃地、坑塘水面、水利设施林带、盐碱地、沙地和裸地。总结前人研究结果,不同研究者的结果差异很大,宜能非粮地的面积包括林地在3 420~16 374 万hm2,不包括林地在700~6 473 万hm2,在各省市区分布上的结果差异也很大。进一步研究方向是制定相关行业标准,以更准确地确定宜能非粮地资源分布和生产潜力,建立不改变土地用途的、因地制宜的土地利用规范,并加强政策性管理方法的研究。 |

| Abstract: |
| It is of significance that evaluating land availability for energy plant production under the condition of not affecting the food security negatively in China.This paper reviewed the current progress of researches in this field.After the related terminologies suggested by previous researcher were discussed intensively, the marginal land suitable for energy plant production (MLSEP) and non-food land suitable for energy plant production (NLSEP) as synonyms were concluded as the most appropriate terminologies.It was defined as the land which was not suitable for food crop production economically or ecologically but satisfied the basic requirements for large scale non-food energy plant production, including the natural system for harvesting aboveground biomass without cultivation.The possible categories of NLSEP were identified as cultivated land and orchard land which were not suitable for food and fruit production, forest land, waste grass land, reclaimable mining abandoned land, water lever of pond, forest belt of water conservancy facilities, saline-alkali soil, sand and bare land.The NLSEP area potential and its distribution exhibited considerable variation between previous researchers, i e.total potential between 3 420-16 374 × 104 hm2 including forest land and that between 700－6 473 × 104 hm2 excluding forest land.Further studies on related industry standards, more accurate land availably and production potential assessment, proper land utilization requirement without change land use, and administrative regulation were suggested. |
