【摘要】 运用冷热点分析法、变异系数法等方法,研究河南省农区经济的演化特征,借助Arc GIS软件对河南省106个县级单元进行空间可视化分析。结果表明:(1)河南省农区经济区域差异较为明显,区域经济发展不均衡现象突出;中低收入水平区占主体;中北部地区经济水平较高,东南部较低,经济发展水平大体呈现从西北向东南部逐渐降低的变化规律。(2)以各年份农民人均纯收入数据进行冷热点分析,热点区集中分布在中部和西北部地区,呈增加趋势,冷点区由分散向东南部区域集中分布转变,热点区和冷点区的整体呈现先增加后稳定的态势。(3)河南省农区经济整体增长速度空间上表现为先增加后缩小趋势,区域增长的空间差异明显,西北部增长速度大于东南部地区。更多还原

【Abstract】 Using the methods of cold hotspot analysis,coefficient of variation and other methods,using ArcGIS analysis software,spatial visualization analysis of 106 county-level units in Henan Province was conducted. The conclusions are as follows:(1) The regional economic differences in rural areas of Henan Province is more obvious,and the unbalanced regional economic development is prominent; the middle and low-income level areas occupy the main body; the agricultural areas in the central and northern regions have higher economic levels,and the southeast is relatively low,and the level of economic development in rural areas generally shows a pattern of gradual reduction from northwest to southeast.(2) The hotspots are concentrated in the central and northwestern regions,showing an increasing trend. The coldspot area is decentralized and distributed in the southeastern region. The hotspots and coldspots are concentrated. The overall scope of the point area shows a stable trend.(3) The overall economic growth rate of the agricultural areas in Henan Province appears to increase first and then decrease afterwards. The spatial difference in regional growth is obvious,and the growth rate in the northwest is greater than that in the southeast. Finally,the main problems in the economic development of rural areas in Henan Province and the development ideas have been discussed.更多还原
