生物燃料作为一种可再生能源，引起了中国和世界各国的高度关注。出于国家粮食安全的考虑，中国自2007年起将生物燃料的发展重点从粮食生物燃料转向非粮生物燃料，包括林基生物柴油。麻风树是生物柴油的主要原料之一。然而，关于扩大麻风树种植面积的土地供应问题的争论日益激烈。本文的总体目标是评估中国麻疯树用作生物柴油原料的潜在土地。本研究基于土地利用遥感数据、气象、土壤、坡度、麻风树适宜种植环境等数据，采用农业生态区划法，考虑社会经济约束条件，对我国麻疯树主产区西南地区潜在的麻风树适宜种植用地进行了评价。结果表明，虽然有一些潜在的土地可以扩大麻风树种植面积，但这些土地的数量很难达到政府未来发展麻风树生物柴油的目标。中国可能需要重新考虑其麻风树生物柴油开发的长期目标。
As a renewable energy, biofuel has attracted great attention in China and the rest of world. Concerned with the national food security, China recently has shifted its biofuel development priority from grain-based to non-grain-based biofuels, including forest-based biodiesel, since 2007.Jatropha curcasis one of major biodiesel feedstocks. However, there is rising debate on availability of land for expandingJatropha curcasareas. The overall goal of this paper is to evaluate potential land forJatropha curcasused as feedstock for biodiesel in China. Based on remote sensing data on land use, data on meteorological, soil and land slope, and suitable environment forJatropha curcasplantation, this study uses Agro Ecological Zone method and considers social-economic constraints to evaluate potential suitable land forJatropha curcasplantation in China’s majorJatropha curcasproduction region, Southwest China. The results show that while there are some potential lands to expandJatropha curcasareas, amount of these lands will hardly meet the government’s target forJatropha curcas-based biodiesels development in the future. China may need to reconsider its long-term targets on the development ofJatropha curcas-based biodiesels.
