摘要
论文选用2007年和2013年我国31个省份(港澳台除外)的单位耕地面积大中型拖拉机、小型拖拉机、大中型拖拉机配套农具、小型拖拉机配套农具、农用排灌机械、联合收割机和机动脱粒机的数量共8个指标,通过系统聚类分析,结合GIS的可视化技术,对我国的农机拥有量进行区域划分,并对分类结果进行差异性分析,从而为各省的农机科学发展提供相应的建议,促进我国农业现代化的实现。
In this paper,eight factors of31provinces of China in2007and2013are selected,including the number of largeand medium-sized tractors,small tractors,large and medium-sized tractor tools,small tractor tools,agricultural irrigation machin?ery,combine harvester and motorized threshing machine per unit cultivated land area.By hierarchical cluster analysis,combinedwith GIS visualization technology,the regional division of the China agricultural machinery possession and the difference analysis ofthe classification results are made,so as to provide some suggestions for the development of agricultural science,and promote the re?alization of agricultural modernization in China.
