摘要：

为了准确了解丰都县的耕地利用现状，笔者利用数据包络分析（DEA）方法分析了2002—2008年丰都县耕地利用效率变化情况，研究了各土地利用分区之间的差异，并运用SPSS软件探讨了耕地利用效率的影响因素及其影响程度。研究发现：2002—2008年丰都县耕地利用效率波动上升，平均综合效率为0.85，耕地利用效率整体不高，还有一定的上升空间；耕地利用效率的变化主要是由纯技术效率的变化引起，原因是纯技术效率与综合效率的变化趋势基本相同；各土地利用分区之间的耕地利用效率差异较大；影响耕地利用效率的因素有很多，按照影响程度由大到小排序为：经济条件>自然条件>耕地资源禀赋。

Abstract:

In order to find out the current situation of cultivated land use efficiency in Fengdu county, this article calculated cultivated land use efficiency, its variation and the difference between land-use zonings in 2002-2008 using the method of data envelopment analysis (DEA). Finally, according to the software of SPSS impacting factors cultivated land use efficiency were analyzed. The results suggested that the calculated use efficiency fluctuated in 2002-2008, the average efficiency was 0.85, which indicated land use efficiency was low, and there was a certain ascendant space. Cultivated land use efficiency and pure technical efficiency had the same change trend, which farther showed that the change of cultivated land use efficiency mainly induced by pure technical efficiency. Meanwhile, cultivated land use efficiency was different among 4 zonings in Fengdu county. There were many factors impacted on land use efficiency, which could be lined as follows from high degree to low, the development of economy, natural environment and the distribution of cultivated land resource.
