摘要
以县域为基本单元,在综合考虑各县农业机械化水平及其增长速度的基础上,运用象限图法和泰尔指数法,分析了湖北不同县域农机化发展类型的时空变化趋势,结果表明:湖北县域农机化表现出不同的发展类型,且在平原、丘陵、山区之间以及各县之间呈现分异性。发展活跃型和滞后型的县域数量居多,活跃型和潜力型县域从北至南绵延平原丘陵交错、国道贯通的中部地带,缓慢型县域集中于武汉城市圈的偏东地带,滞后型县域则聚集在西部和东南部偏远山区。泰尔指数分析结果表明,在区域总体相对差异缩小的同时,三大地形区组内、组间差异以及各地形区内县域之间的差异都在缩小,组内差异是区域总差异的主要贡献者,但组间差异的贡献率呈上升趋势。
Abstra~： Selecting county level administrative regions as study unit, combining both agricultural mechanization level and its annual growth rate, this paper studied the spatial and temporal changes of the diverse mechanization development types through the quadrant map and Theil .index. The results show that the development patterns of county agricultural mechanization are different in Hubei. The differences also exist between three topographic regions and inside regions. There are large numbers of dynamic and stagnation counties. Dynamic and potential counties staggered throughout the middle belt of Hubei from north to south, where plain and hilly stretched and national roads wandered through. Most of slow counties set in eastern Wuhan Metropolitan Area, and stagnation counties concentrated in remote west and southeast mountainous areas. The disparities evaluated by Theil index between the regions and inside regions are continuously decreasing, and the disparity inside regions is the main contributor of the regional inequality. Key words： agricultural mechanization; regional inequality; terrain; spatial-temporal structure evolution; Hubei
