摘要
为了了解江西省耕地利用状况,采用数据包络分析(DEA)、Tobit回归模型分析以及聚类分析方法,对江西省1996—2008年耕地利用效率及其影响因素进行了分析。结果表明:l3a来江西省耕地利用效率平均值为0.967,耕地利用总体水平较高;萍乡、赣州、吉安、宜春、抚州5市耕地利用效率较好,新余、鹰潭次之,南昌、景德镇、九江、上饶4市相对较差;人均GDP、耕地复种指数、有效灌溉面积和单位面积机械总动力对耕地利用效率的影响有所差异,单位面积机械总动力>耕地复种指数>有效灌溉面积>人均GDP。研究结果可为提高江西省耕地利用效率提供科学依据。
In order to learn the condition of cultivated land use of Jiangxi Province,this paper studied its cultivated land use efficiency and its influencing factors during 1996—2008by using the method of DEA,Tobitregression model and clustering analysis.The result indicates that the average value of comprehensive efficiency of cultivated land use is 0.967 in Jiangxi Province over the past 13 years,and the average value is relatively high.The cultivated land use efficiency of Pingxiang,Ganzhou,Ji′an,Yichun and Fuzhou is better than Xinyu and Yingtan,and 4efficiency of the 4cities such as Nanchang,Jingdezhen,Jiujiang,shangrao is relatively low.We can also find that per capita GDP,cultivated cropping density,effectively irrigated area,total mechanical power on unit area have different impacts on cultivated land use efficiency,the impact order is mechanical total power on unit area〉cultivated cropping densityeffective irrigated area〉Per capita GDP.Finally,the results provide scientific basis for improving land use efficiency in Jiangxi Province.
