基于农户的能源作物种植成本收益及替代性研究——以云南省临沧市膏桐种植为例

Study of Energy Crops Planting Cost-Income and Its Substitution Based on the Households——A case study on jatropha planting in Lincang city,Yunnan province

以云南省临沧市膏桐种植为例,探讨农户参与膏桐种植的几种方式,重点分析农户在不同模式下的成本收益状况,并比较膏桐与其它农作物之间的替代关系。结果表明:目前种植膏桐的经济效益不高,但膏桐对山地作物有良好的替代性,未来发展有赖于种植模式的进一步优化;下游成品油的价格走势对能源作物的推广会带来系统风险。

Taking jatropha planting in Lincang city as an example, the paper discusses the three ways of the households took part in the jatropha planting. Focus on the cost-income of households in different patterns, and analyses the substitution capacity to other corps. It＇s found that planting jatropha is not a good way for the households to gain earnings, and jatropha is a good substitution for mountain plants. The further move of this industry relay on the optimization of the jatropha planting patterns and the changing price of petroleum will bring risks for the jatropha planting.
