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。
In recent years, China does not affect food security, the appropriate development of energy plant production of land resources research results for a comprehensive review. It is the most appropriate term to analyze the definition of a concept, to determine whether it is desirable or not to be marginal as a synonym, and to define as a condition that is economically or ecologically unfit for producing food but possesses the requirements for the growth of an energy plant suitable for Large-scale cultivation or natural growth of non-food-energy plant land. Discuss and determine the types of land that should be included in the non-food land, namely, arable land and garden not suitable for food crops and fruit trees, suitable forest, grassland, reclaimed industrial and mining wasteland, pit surface, water conservancy facilities, saline land, sand Ground and bare ground. Summarizing the results of our predecessors, the results of different researchers vary widely. The area that should be non-grain land includes 3420-1674 million hm2 of forest land, excluding 700-647 million hm2 of forest land, and the distribution in various provinces The result is also very different. Further research is to develop relevant industry standards to more accurately determine the potential distribution of non-food land resources and production potential, to establish land use norms, and to strengthen the study of policy-based management practices.
