摘要: 利用气候、土壤、地形和土壤等数据,运用ArcGIS的空间叠加分析功能,分析了中国木薯乙醇的分布生产潜力及空间分布。结果表明:中国适宜木薯分布的区域主要在广西、广东、福建、云南、江西和海南等广大南部地区,这些地区的木薯乙醇生产潜力也最高;适宜木薯种植的未利用地面积较少,仅有1.53×10.4 hm2,其乙醇生产潜力仅能满足目前中国E10汽油约1.0%的乙醇需求量;要满足中国目前E10汽油的全部乙醇需求,需要扩大目前木薯总种植耕地面积的4.4~5.7倍,而中国的粮食安全需求则限制了该目标的实现;中国木薯乙醇满足未来生物乙醇的需求前景不容乐观,中国木薯乙醇企业的发展规划要充分考虑原料的可获性,切不可盲目扩大生产。

Abstract: In this paper, the cassava’s ethanol productive potential and its spatial distribution in China were analyzed, based on the climatic, topographic and soil data, and by the method of ArcGIS 9.2 spatial analysis. In this country, the regions suitable for planting cassava and with the highest cassava’s ethanol productive potential mainly distributed in the southern provinces such as Guangxi, Guangdong, Fujian, Yunnan, Jiangxi, and Hainan. However, the suitable but unused lands for cassava in these regions were quite small, only 1.53×10.4 hm2, and the cassava’s ethanol productive potential from these lands could only satisfy 1.0% of the China total demand for E10 ethanol gasoline. To fully satisfy the present demand for E10 ethanol gasoline in China, the total area for planting cassava would be expanded 4.7-5.7 times, which is hard to achieve, considering China’s food security. Therefore, the prospect that the present cassava’s ethanol production in China could meet the future demand for bioethanol of the country would be not optimistic. It was suggested that in the development planning of cassava ethanol, our related institutions and industries should fully consider the availability of raw materials, and not enlarge the cassava ethanol production blindly.
