摘 要:为了测算和衡量湖南省农业两型化水平,促进农产品种植结构优化,从两型农业的角度出发,运用生态足迹理论,对2009年湖南省主要农产品的生态足迹和产值足迹进行测算。结果表明:湖南省主要农产品的产值足迹各有不同,糖料和烟叶的产值足迹具有很大优势。棉花、稻谷、麻类、豆类、玉米、薯类和油籽的产值足迹处于较低水平,而小麦的产值足迹要远高于其他农作物,生态效益为最低。从效益足迹方面来看,糖料、麻类投入回报高,具有很大的经济效益,小麦的效益足迹为负值,居于经济效益弱势地位。结合此结论以及农产品效益足迹分析湖南农业两型化趋势,提出了以经济、生态综合效益最大化为原则的农产品种植结构优化模型和建议。In order to calculate and judge level of the two-oriented agriculture in Hunan, and promote the optimization of agricultural planting structure, Basing on ecological footprint theory, the author calculated the ecological footprint and the output value of footprint of the main agricultural products in Hunan Province in 2009 from the perspective of the two-oriented agriculture. The results showed that: the output value of footprint of the main agricultural products in Hunan was different, output value of footprint of sugar and tobacco leaf had great advantage. Output value of footprint of cotton, rice, hemp, beans, corn, potato and oilseeds were on low level, while output value of footprint of wheat was much higher than others, which was the lowest. From the perspective of benefit footprint, sugar and hemp had high return and great economic benefits, while benefit footprint of wheat was negative, it was at a vulnerable position. By combining with the conclusion and agricultural benefit footprint,the author analyzed the trend of the two-oriented agriculture of Hunan and put forward a model of optimization of planting structure and some recommendations following the principle of maximize economical and ecological potential.
