河南省美丽乡村空间分异特征研究

Spatial Distribution Research of Beautiful Countryside: A Case Study in Henan Province

  • 摘要: 河南省自2013年启动美丽乡村建设试点以来,美丽乡村数量及空间布局迅速变化.基于Voronoi图变异系数、标准差椭圆等方法,研究了河南省2013-2017年美丽乡村空间分异特征及变化趋势.结果表明:河南省美丽乡村总体数量急剧增加,在市域尺度美丽乡村数量趋于均衡化;省域尺度及区域尺度下空间分布模式均具有随机分布向集聚分布转变的特征,但转变强度具有区域差异性,但区域之间空间分布模式的呈现趋同性特征;河南省美丽乡村空间分布重心总体向北移动,不同研究断面移动方向与速度不同;美丽乡村的分布呈现空间收缩,方向性减弱、分布轴线向正南-正北方向接近的特征.

     

    Abstract: The Voronoi coefficient of variation and standard deviational ellipse methods were employed to study the characteristics and the change trend of spatial distribution of the beautiful countryside based on the beautiful countryside data from 2013 to 2017 in Henan province. The results show that:While the number of beautiful countryside in Henan has increased dramatically, the number is becoming more and more balanced in city scale;The spatial distribution patterns in the provincial and regional scales were changing from random distribution to cluster distribution,but the intensity of the changes in different regions is atypism, and the differ among different regions in spatial distribution patterns gradually decreases;The spatial distribution gravity of the beautiful countryside in Henan province moves northward in the mass and the moving speed and direction are different among different cross section in time;The distribution space is shrinking grandually;the direction characteristicis becoming weaker.In addition, the axis of spatial distribution is approaching to the due south-north direction.
