摘要
农业机械化是农业现代化建设的重要内容。为此,以县域为基本研究单元,利用变异系数与艾肯森指数等区域差异研究方法对河南省2004-2013年近10年的农业机械动力投入进行动态差异分析,并采用探索性空间分析方法(ESDA),在Arc GIS与Deo Da095i软件的支持下,分析近10年来河南省农业机械动力投入的时空格局与时空演变特征。结果表明:2004-2013年,河南省县域农业机械动力投入均值呈显著的增长趋势,但整体区域差异呈现出逐渐缩小的态势;2004-2013年河南省县域农业机械动力投入之间存在显著的空间正相关,表现出明显的空间集聚现象,但农业机械动力投入水平相似的县域在空间上的集聚态势会逐渐降低;局部空间集聚格局,总体呈现出东北部较高而西南与东南部较低的特征;2004-2013年整体空间分布位置变化不大,数量上有明显变化,高高集聚与低低集聚型县域数量总体呈现出明显减少的趋势,各县(县级市)趋向于平衡化的发展。
The agricultural mechanization is the important content of agricultural modernization .Taking county as the bas-ic research unit , using the coefficient of variation and Atkinson index of regional differences in research methods , to ana-lyses dynamic differences of agriculture mechanical power input in Henan province during 2004-2013 years, and used the exploratory spatial analysis method (ESDA), with the support of ArcGIS and DeoDa095i software, to analyze space-time spatial and temporal evolution characteristics of county agricultural mechanical power in Henan province in recent 10 years.The results show that: The average of agricultural mechanical power in each county presented growth trend in Henan province during 2004-2013 years, but the overall regional difference showed a tendency of shrinking;The coun-ty agricultural mechanical power showed a significant spatial positive correlation from 2004 to 2013 in Henan province , and showed obvious spatial agglomeration phenomenon; Local spatial agglomeration showed that northeast was relatively high and the southwest and southeast was lower; The number of counties of high concentration and low concentration is showing a trend of decreased , the counties trend to balance development .
